The "Capable BCG" from SOLGW is an exclusive variation on Sons of Liberty Gun Work's fantastic BCG.  No expense is spared here in terms of reliability and quality.  These carriers are covered by the SOLGW lifetime warranty, full auto test fired, HPT/MPI'ed and guarantied to impress.

Our Capable BCG starts as a SOLGW Phosphate Bolt Carrier Group, with just a few enhancements.

1) The cam pin is laser engraved with our reduced size Capable Citizen logo - this provides an quick visual reference so that the cam pin can be reinstalled in a consistent orientation after any disassembly for cleaning.  Greater minds than us have dug into the science behind the interaction of these parts, but maintaining the alignment of the cam pin and not reversing it 180 degrees back and forth, leads to less "wobble" being developed as the parts wear in, potentially extending the service life of the parts.  As of 2022 we've offset the logo to the side as well, making it easier to identify the orientation even if it's a little dirty and you can't see the detailed logo as well.

2) OCKS (Optimized Carrier Key Screws - made by the famous Ned Christiansen), are used to secure the carrier gas key.  The OCKS have a sidewall on the screws more like a "mud tire" on a truck than the traditional serrations found on other fasteners.  By decreasing the quantity of serrations and increasing their depth, the metal displaced while staking the sides of the gas key forms an even stronger mechanical bond with the screws than is possible with traditional profile screws.  While a properly torqued and staked gas key isn't likely to ever fail you, this is our "belt and suspenders", above and beyond level of durability we've chosen for the Capable BCG.

3) The SOLGW Rebellious Stripes have been laser engraved at a higher output level for a brilliant color logo on the carrier.  Visually there's no mistaking that this is a one of a kind BCG from an industry leader in BCG's.

Excellent Product
Great product and fast shipping. This is my second bcg from them. First one has been flawless and I expect nothing different from this one. If you never had a SOLGW products they are worth the investment.

Excellent BCG. In my opinion, one of the best. This was my first time buying from Capable Citizen. Very impressed with their service. I received a shipping confirmation from them in less than an hour of placing my order. They gained a customer in me. Thank you CC!
