4K Rounds and counting.

Waited to review this item. Arrived quick within a weeks period. One it came in I decided to right away change the extractor spring and o-ring to the BCM enhanced set. Outside of all that she’s been down 3k of steel and 1k of brass. So far no signs of wear on it.

Great premium BCG

This appears to be a very high quality BCG made from the premier manufacturer in the industry. I bought a new Colt 6920 SOCOM late last year, and the BCG that came with it didn't have a "C" or "MPC" on it. But it did look EXACTLY like this one from EXPO. Both also have aggressive gas key staking. I believe they are made by the same company. Meaning it's right there with BCM and SOLGW BCG's.

good to go

Very nice finish, machining and construction. All the interior bore surfaces are extremely smooth. Cycled brass and steel case ammo just fine. Nice ejection pattern. All components are wearing in nicely. I am very pleased

Tier 1 BCG

Awesome BCG. It seems as it is the same quality as some tier 1 BCGs in the game. Wouldn't hesitate to buy another one.

I dig it.
