Retac Rifleworks™ 16″ 5.56 NATO Barrel


SKU: AR15-BAR-MID16-4150 Categories: , Tag:

Upgrade your life by adding one of our barrels to your rifle. We designed them for the refined (ha, that term is used loosely) modern shooter who likes to run suppressed and unsuppressed. These barrels do great in both scenarios without needing any tinkering or adjusting. Just slap on your can and send rounds down range!

Since the barrel is one of the most critical components in your rifle, we designed it with a mid-length gas system for a proper dwell time, a 1:7 twist rate for proper projectile flight and an M4 profile for balance and accuracy.

Balance, versatility and performance

With a sub-MOA guarantee, you better believe they’re accurate. We chose to use 4150 Chrome Moly Vanadium, button-rifled, barrels to give you more accuracy and a great length of life. We believe in them so much that if you shoot one out, we’ll send you a new one!

Input for our barrels was received by consumers and military end users so we can offer you a barrel that’s truly been tested and approved.
