As a company our goal has always been to introduce a line of products under the APE banner that not only looked good on paper but exceeded our expectations during performance and is affordable. We introduce to you the first barrel from our The Peoples Champ (TPC) line of barrels, the 13.9″ 5.56. This barrel performed flawlessly suppressed, unsuppressed and endured numerous function tests and most importantly accuracy. We shot a variety of ammunition from Winchester 55GR to Match 77GR TMK and was able to shoot numerous 1/2 inch (.5 MOA) groups at 100 yards. With a majority of the popular muzzle devices on the market you can achieve a 16″ OAL once pinned and welded. This barrel is manufactured for us by one of the best companies in the industry that has provided us with affordable, performance driven barrels for 10+ years.

    Quality barrel and performance so far. Only 100 rounds through it, but both Federal 75gr and home reloaded 77gr had sub moa groups. Cant wait to put more rounds through and test longevity. Id recommend this barrel for a new build.

    Save your money for a real barrel, this is just a basic mass produced barrel with an ape logo on it.

    High quality barrel, my new favorite barrel length many manufacturers are offering muzzle devices specifically for the 13.7-13.9 length so it gives you the perfect length to keep the barrel length as close to 16 as possible.

    Love this barrel so far! The initial quality is amazing, and the length is about perfect for doing a pin and weld for most muzzle devices. Pinned a surefire warcomp on and came out at 16 1/8 OAL!

    The machining is superb just like everything else that Ape carries, the groupings this barrel produces are outstanding! If you’re looking to build a shorter rifle but still be able to reach out this is it!
