The Barrett Model 99 "Big Shot" is a single-shot long-range precision rifle that was first introduced in 1999 by the Barrett Firearms Company as a less expensive alternative to the company's higher-priced offerings.〔 The rifle uses a bullpup single-shot configuration meaning a single round is loaded behind the pistol grip. This Barrett Firearms Company is known worldwide for the .50 caliber rifles, mostly the M82A1 magazine fed semi-automatic rifle. The model 99 is designed for one purpose only, hard–core construction and surprisingly few moving parts with dead on accuracy. Math winning accuracy with smooth functionality shot after shot, the Barrett M99 is competition ready.
==Design==
The Model 99 rifle is a single shot bullpup type of rifle that debuted in 1999. Its primary market was for long range competitive target shooters and in 2001 a shooter set a world record at 1,000-yards with the M99 by shooting a 5-shot group which measured 4.09″. The M99 features a hard-core construction, 7000 series aluminum alloy extrusion, match-quality trigger design, heat-treated steel M1913 rail, match grade barrel, and S-7 tool steel bolt. Using the three quick assembly pins the M99 is easily disassembled without the use of tools. The Model 99 is very accurate over and over again because of its heavier contour barrel. With the .416 round, the accuracy, and increased velocity, enables an incredible long range precision. The bolt is machined from a single piece of S-7 tool steel. Making a weapon that is very reliable and easy to maintain must have very few moving parts, this weapon does this by having just these parts move, the extractor, ejector and firing pin assembly. The Model 99 uses only three pins for a quick disassemble holding the trigger housing and bolt guide to the receiver assembly. For bench rest shooting the bi-pod can be easily detached, the design in the match-quality trigger is virtually maintenance free.〔 The rock solid match-tolerance barrel is locked into the extrusion by being hydraulically pressed making it able to mount a rifle scope on it. The high grade steel gun barrel and the aluminum extrusion surrounds the cartridge making safety unparalleled.
