    build and performance

    Posted by David Dixon on May 11th 2021

    After receiving this buffer , I noticed an awesome quality of build. It had a very smooth and consistant feel in its build and craftsmanship. After installation, the recoil was tamed to an extremely soft kick, and timing of my overgased system was improved to a very nice 3 oclock ejection.

    The H 1 Carbine Buffer for 20" CHF 5.56 Heavy Barrel

    Coupled with an M 16 buffer spring , this combo has the right return strength to keep good timing when firing in FA. Price is never a consideration when your life depends on excellence.

    H Buffer

    As advertiesed... tuned ejection perfectly for a 10.5" 300 blk upper from PSA. They are marked "H1" now instead of "H".

    H Buffer

    This H buffer completely improved the recoil impulse in my rifle when shooting 77 grain ammo. A good buffer and spring is such an underrated improvement to a rifle.

    Just what I was looking for

    Did exactly what I needed it to do. A buffer is pretty straightforward. This one seems to be very well made and didn't explode, so I'd call that a win.

    Works great! Slowed carrier down and gave more rearward ejection.

    Quality product, looks like Colt and slowed my carrier down for 4 oclock ejection.
