Most Helpful Positive Review Roscoe BCG
I have 3 of these now to match their 14.5" Bloodline barrel. I recently bought the Hotsauce pack that has BCG, 12.5" barrel, gas block and gas tube. Like everything I've gotten from Roscoe so far it exceeds their price point by far. Their packaging alone looks more expensive than premium parts from other manufacturers. Their coating is also great, deep and dark Nitride finish that looks great.

so far so good

by G3 Dimitri, Verified Owner from TX, United States Written on April 19, 2025
Just threw on some lube and let her rip, zero issues with feeding or extracting so far. Paired with a rosco barrel to avoid any headspace issues

good price for a step above milspec

by neb grendel, Verified Owner from NE, United States Written on December 31, 2024
The bcg has the quality you would expect from a company like roscoe. This is going in a 10.5 300blk project paired with a roscoe barrel. Head spaces perfectly as it should. Havent had a chance to get to the range but not aticipating any issues.
Pros:
  • Quality
  • Finish
Cons:
  • price (but it's worth it if you need reliability and quality)
Best Used for:
  • 5.56 or 300blk
Would recommend: Yes
