24" 308/7.62x51 Stainless Bull Contour Barrel AR10/LR308 Rifle Upper Assembly with 15" M-LOK Rail and Thread Protector
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.

DPMS 308 buildGood looking upper. Haven’t shot it yet.todd froelich
Ar10 308 upperEverything shipped out in a timely fashion , put product together and runs good . Only one complaint is the steel ASC magazine is junk , bolt was hanging up on magazine , went out and bought a magpul 20 round magazine and no jamming no malfunctions run like a champ . I would recommend to discontinue selling the ASC steel magazine and sell ones that are reliable and function properly.dale plyter

24" 308 Winchester Upper Stainless Steel Bull Barrso, I ordered around 11am and received an email in the afternoon of the same day around 5pm that my order has shipped. I have not test fired the gun yet as the gun range remained close due to covid19. however, so far it's been great because they were able to send my order quickly. I just hope that it wasn't too quick that the upper was not tested to fire before it was sent to me. I did punch the bore and there were trace of burned powder which indicates that they may have test fired it. but, I'm not one to believe it until I see it for myself, its the reason why I need to test fire it. overall, the upper looks good, clean, no scratches, nothing seemed like some parts were forced to fit it. I will send an update of it's performance when I finally get to test it. that's why for now I can only give it 4 stars because I'm not able to test it yet, changes will occur after the test.Eino Williams
Aero m5 upper 24" bull barrelGreat communication with these guys, complete upper arrived shortly after they got back from the SHOT show. Had a change, they made it happen. Everything looks great, build starts in earnest now.
