    If you want a solid bcg that is easy to clean without the cost of NiB this is it. Bkingsfirearms and Aero performs!

    BCG looks great, I have yet to fire the gun.

  5. Colten (verified owner)

    As a BCG should be. Staking was okay, not my most favorite but zero issues.

  6. George S Potter (verified owner)

    Awesome BCG. Coating is superb and staking is perfect. Several hundred rounds down range without issue. Easy to clean.

  7. Rafed K. (verified owner)

    Great product.

  8. Jesse H. (verified owner)

    Solid BCG from Tool Craft and paired with a no questions asked lifetime warranty it’s hard to beat for the price. I would however note that the staking could have been better. Only time will tell if the gas key will move. Overall, solid thus far.
