20" 308/7.62x51 Parkerized Heavy Contour Barrel AR10/LR308 Rifle Upper Assembly with 15" M-LOK Rail and A2 Flash Hider
During the 1940s Winchester saw a market for a civilian model of the late T65 series designs and introduced the 308 in 1952. Since then, the .308 Winchester has become the most popular short-action big-game-hunting cartridge worldwide. The relatively short case makes the .308 Winchester especially well-adapted for short-action rifles. The .308 Winchester has slightly more drop at long range than the 30-06, owing to its slightly lower (around 30 metres per second (100 ft/s)) muzzle velocity with most bullet weights. Cartridges with significantly higher muzzle velocities, such as the 300 Magnum can have significantly less drop at long range, but much higher recoil. The relatively short case makes the .308 Winchester especially well-adapted for short-action rifles. When loaded with a bullet that expands, tumbles, or fragments in tissue, this cartridge is capable of high terminal performance.

OutstandingOrdered on Friday, received upper this morning, Wednesday! Well packed, in perfect condition. A close inspection found no flaws. As soon as lower is completed fit and accuracy will be checked. This experience speaks volumes about AR15part's ability and determination to provide quality components and outstanding service at reasonable prices. Especially when virtually everyone else is having problems making delivery weeks or even months behind schedule. OUTSTANDING!!!Kenneth Loehr
Amazing qualityBetter than expected!!!Big Ape
Excellent out of the box!I was sold on the choice of upper to lower fitment. I didn't know I was going to actually get the same make upper receiver as my lower. Everything that came with this is excellent. High quality and reasonably priced! I have no doubts the barrel will get me out to 800-1000 with little problem. I will definitely look to ar15part again for future builds that won't break the bank.Ashley Brown

Functioned perfectlyFitted barreled upper, lantac ebcg .308, radian raptor ambi charging handle, and gen 3 pa 10 lower, first 50 rounds no flaws or failures. Would absolutey reccomend, also while everybody else I ordered any other part from (midway usa and Amazon) saw no mention of delays thanks to the bud lite virus, ar15 mentioned nothing of the issue and had a email confirming shipment with a tracking number within 48 hours of my purchase, nothing was wrong with my order so I can not comment on the easy of customer service.Scott Burke
Best price around.I’m super happy with quality and service. I will definitely be buying more from ar15part.com
