The ArmaLite AR is a 7. However, the ArmaLite AR would become the progenitor for a wide range of firearms. Inthe basic AR design was rescaled and substantially modified by ArmaLite to accommodate the. With the expiration of its patent, other manufacturers began producing their own variants, known as AR style rifles. ArmaLite began as a small engineering concern founded by George Sullivan, the patent counsel for Lockheed Corporation, and funded by Fairchild Engine and Airplane Corporation.

With its limited capital and tiny machine shop, ArmaLite was never intended to be an arms manufacturer. Sullivan leased a small machine shop in Hollywood, California, [8] hired several employees, and began work on a prototype for a lightweight survival rifle for use by downed aircrew.

While testing the prototype of the Armalite AR-5 survival rifle design at a local shooting range, Sullivan met Eugene Stonera small arms inventor, whom Sullivan hired to be ArmaLite's chief design engineer. At the time, ArmaLite Inc. The first prototypes of the 7. Springfield Armory 's T44E4 and heavier T44E5 were essentially updated versions of the Garand chambered for the new 7.

ArmaLite's AR entered the competition late, hurriedly submitting two hand-built 'production' AR rifles based on the fourth prototype in the fall of to the United States Army's Springfield Armory for testing. The final Springfield Armory report advised against the adoption of the rifle, stating that it would take "five years or more to take it through tests to adoption".

Army infantry forces urgently required a modern, magazine-fed infantry rifle to replace the M1. That same year, ArmaLite completed about 50 production AR rifles at its workshop for use as demonstrator models for its sales agents, including Samuel Cummingsa famous international arms dealer.

With its large factory and production facilities, A. In Cummings secured an order of 7, AR rifles from Nicaragua, with an initial delivery of 1, rifles to be delivered before January With the AR in short supply, Cummings left his personal demonstrator rifle with Nicaragua's chief military commander, General Anastasio Somozawho personally conducted the endurance test trial.

While General Somoza was firing this rifle for the trial, the bolt lug over the ejector sheared off and flew past Somoza's head.

The general angrily returned Cummings' AR and canceled the entire Nicaraguan order.

The remaining Hollywood rifles were inspected and refitted as necessary with new parts to prevent reoccurrence of the bolt lug failure, but the Nicaraguan order was lost for good. Firearms historians have separated AR production under the A. The three main variants have been termed the Sudanese model, the Transitionaland the Portuguese model AR The Sudanese version derives its name from the sale of approximately 2, AR rifles of to the government of Sudan in The Sudanese model was equipped with a very lightweight, fluted steel barrel fitted with a trim, prong-style flash suppressor, a bayonet lug, lightweight fiberglass furniture, and sight graduations in Arabic.

Ina special 7. Germany, Austria, the Netherlands, Finland, and South Africa also purchased small numbers of the AR for test purposes, and Cuba's Batista government ordered "Transitional" model rifles in The Cuban order was delivered to Havana, but in December Fidel Castro 's forces took control of the country, including the warehouse containing the AR shipment.

However, rapidly worsening relations with the United States eliminated any chance of future AR sales to Cuba, and Castro transferred the ex-Batista ARs to a group of Communist revolutionaries from the Dominican Republic. In Junethe rebels, led by Cuban officers, invaded the Dominican Republic. This final version incorporated all that had been learned to date about the AR, including infantry service rifle and field test reports. As one police instructor in the Congo stated, "It was a good combat weapon that never failed me; a bit too long but not as bad as the FAL or M14 for house-to-house work or really heavy brush, but great for meters, in the flats - and really nice on the body, after wandering around hours looking for bad guys.

Some Portuguese-model ARs were fitted with A. The AR's built-in gas cutoff design enabled it to fire Energa rifle grenades without adjustment of the gas system, and the self-loading action would even eject the spent blank shells and load the next one, allowing several grenades to be quickly fired.

The added recoil took its toll on rifle stocks, and some Portuguese rifles were retrofitted with all-metal butt stocks to better withstand the strain caused by firing the heavy grenades. Fairchild-ArmaLite was dissatisfied with the delays in setting up the tooling and production at A. By that time, fewer than 10, ARs had been produced, mostly military select-fire rifles, with a few semi-automatic only rifles produced for civilian use.Getting started in sport shooting Your sport.

To compare Remove list.Field Target Shooting has gone from strength to strength over the last couple of decades, with a national network of clubs and tournaments, spreading the word to an ever wider audience. A World Championship title is keenly contested, and the fact that such an event is now rarely staged in the UK is testament indeed as to the genuine worldwide popularity of FT, as a growing number of countries now get involved.

Taking part in our flagship outdoor airgun sport, however, can require some significant investment, especially when supposed top class match rifles are selected. Walther are obviously serious players in this market sector, and their own target models such as the Dominator, command a high price from enthusiasts, so I was surprised to see the release of this new AR20FT model, under the Hammerli brand name, since this famous old name now sits within the Walther company portfolio.

Having now spent some time fully evaluating this AR20FT, I can report that it not only delivers on that score, but also represents astonishing value for money, when compared to most of its rivals. FT demands certain properties from a scope, such as high magnification and parallax adjustment.

This Walther has an ideal spec, providing a maximum mag of 32x, and from initial testing down range, performance seemed fine. As is so often the case with this style of scope though, the factory set range markings on both the side knob and extender wheel came in a few yards adrift from the actual target ranges viewed.

What matters however, is consistency, and range-finding came in to the same mark on the dial. In the real world, any competitor is best to take the time to add their own tried and tested fine markings to the wheel; calculated over several shooting sessions to ensure accurate readings. This means the action can start pretty well from the off. Turrets are of the target variety and turn with reasonably positive clicks. Those all important graduation lines at the base of each turret offer an invaluable indication as to how many revolutions the turret has been dialled through; thus allowing the shooter to keep a firm check on adjustments and impact point.

Having witnessed several shooters commit the classic error of having wound their scope turret round an extra revolution without realizing and subsequently missing the next target by milesI can appreciate this subtlety on a scope.

Finally, a Mil Dot reticle completes the specification, making this Walther glassware great value as part of the package. Take a moment to list all the features that you would expect to find on a full-blown Field Target rig, and this Hammerli just about sums up the blueprint. Shrouded Lothar Walther barrel, fully adjustable match trigger, adjustable grip, butt and cheek-piece.

Adjustable fore-end, counterweight system, and ambidextrous chassis and loading. Take another glance at that asking price, and it seems incredible. Dovetails run along the full length of the top of the aluminium section, so the positioning of a scope is simplicity itself.

Whilst the butt, grip, fore-end plate, and cheek-piece are all made from composite, the quality of moulding is excellent; with the result that everything feels functional, yet refined. Walther supply a multitude of accessories with this model, and as all-inclusive packages go, it takes some beating.This Funding Opportunity Announcement FOA solicits applications that propose to conduct time-sensitive mechanistic ancillary studies related to the NIAMS mission in conjunction with privately or publicly funded, ongoing clinical projects.

There are several options available to submit your application through Grants. You must use one of these submission options to access the application forms for this opportunity. Clinical studies offer unique experimental windows to study human disease that are often not fully exploited. Mechanistic studies that go beyond the core activities of the original clinical project can explore novel research opportunities offered in the established cohorts and generate new information to enhance the scientific content of the original project.

Such studies that are not part of the original parent project are referred to as ancillary studies. This FOA solicits grant applications that propose to conduct time-sensitive mechanistic studies ancillary to privately or publicly funded, ongoing clinical parent projects. The mechanistic ancillary studies supported under this FOA should focus on areas that are not studied in the parent project and address new research questions that are related to the mission of NIAMS.

The parent project can provide existing resources to facilitate the research and make it more efficient than initiating the same research de novo. The parent projects can be interventional clinical trials, observational clinical studies or disease specific repositories that are actively collecting patient samples or clinical data.

In addition, these clinical projects have to provide sufficient cohorts of well-characterized patients, infrastructure, data, and biological samples.

The objectives of the parent study need not relate to the NIAMS mission, so long as the parent study provides an appropriate venue for the proposed mechanistic ancillary study. The following are examples of research that might be proposed under this FOA. These are only examples and are not meant to be inclusive:. Ancillary studies must not interfere with the parent project or unduly burden participants.

Ancillary studies may involve the entire cohort of participants in a parent study or selected subsets, depending on the scientific questions posed and the sample size required to answer them.

The ancillary studies may also draw patients from two or more parent projects if they are able to obtain approval from these parent projects and if their research plan is feasible. In general, this FOA will not support the recruitment of patients who are not already enrolled in the parent study or studies; however, recruitment of a small number of normal controls is acceptable provided that the cost is minimal e.

Once a parent project clinical protocol is finalized, its investigators often are ready to begin recruiting patients as soon as they obtain Institutional Review Board approval.

This time-sensitive feature demands a robust administrative system within NIAMS that is compatible with the timeline of the parent project to avoid any missed research opportunities; an accelerated review and award process would allow the initiation of ancillary studies in a timely fashion to take advantage of the unique resources and well-characterized cohorts being established in the parent project. Applications submitted to this FOA will be subject to an accelerated peer review and award process.

Examples of characteristics that would support the case for time-sensitivity include 1 the need for support to collect samples or data prior to end of recruitment, 2 the need to perform analysis on soon-to-be-collected fresh specimens, or 3 the need for collecting post-intervention data from research participants in a trial that will end.Page of 17 Go.

It stepped in India 20 years back and since then it has witnessed a continuous growth. Today, Bridgestone is one of the most trusted tyre brands in the Indian passenger car market and stocks a wide range of tyres for all the vehicle segments. Made to combat the challenging Indian road conditions with the ultra-soft compound, Bridgestone Turanza AR20 is a high-rated tyre for mid-segment cars. The company has introduced this tyre in 23 different sizes with varying width and sidewalls for 12 to 15 inches wheels.

Quoted as a successor of Bridgestone ER 60 tyre, the Turanza AR20 gets some remarkable features and capabilities like Flat Contact Patch FCP for improved handling, lightning groove pattern for a better road grip, excellent wet road performance and much more.

Under practical conditions, Bridgestone Turanza AR20 is a commendable performer as it provides top-notch handling and braking both in dry and wet conditions. The traction level of this tyre is remarkably high as the water dispersion is easily carried out through the Lightning Groove pattern.

This tyre also secures high marks in terms of silent driving as the noise level is surprisingly low. Compared to the rival tyres, the Turanza AR20 is slightly expensive.

Bridgestone Turanza AR20 is well known for its fuel-saving capabilities. It is designed to reduce the rolling resistance of the vehicle which results in better traction thereby cutting the fuel consumption significantly. This warranty is valid up to 3 years from the date of purchase or till the exposure of tread wear indicators, whichever is earlier irrespective of kilometres covered.

With various tyre brands available for the mid-segment cars, the competition for Bridgestone AR20 tyre is quite high. Here is the list of cars with which Bridgestone Turanza AR20 is compatible:. Bridgestone Turanza AR20 tyre gets highly durable tread compounds and improved tyre profile which ensure minimum tread wear.

The flexible rubber compound along with new rubber polymers, tread blocks and main groove design makes this tyre safe enough to run in control on wet and dry conditions. Like the other Bridgestone tyres, the Turanza AR20 also comes with a continuous nylon wrap which avails it a higher level of uniformity thereby enabling it to deliver enhanced performance and keep its original shape.

The Flat Contact Patch FCPunlike a traditional tyre, gets squared shoulders which allow a larger tread area to come in contact with the road thereby remarkably improving the handling dynamics.
