    Best spare parts you can buy.

    Posted by Parker Allison on Jul 6th 2020

    If you shoot the AR-15 platform, these are a must. All parts are subject to fail regardless of manufacturer after thousands of rounds, these kits are invaluable if your rifle goes down because of a gas ring, or extractor failure. Plus, they are priced well enough that you can have a few of them laying around. Order this kit with a BCM cam pin and firing pin and you’ll have everything you need to freshen up your bcg.

    First one failed quicker than expected

    Posted by Unknown on Jan 20th 2020

    I bought one of these to replace an extractor I'd worn out. The replacement failed in about 2-3 thousand rounds, but it's possible I didn't install it correctly, and I run my rifles harder than most. I recently replaced that failed extractor again with one of these kits and so far, so good. I'll have to amend this review in another 5 thousand rounds.

    Straight up QUALITY

    My package was at the door ridiculously fast. I ordered a few of these kits, extractor springs, firing pins etc... They are all very well made. Everything came separated and labeled neatly. I stored them away for a rainy day to keep my ar running longer than me. Definitely ordering from here again.
