    Quality and value

    The quality of the parts are second to none and the value of what you get for the money is as well.

    The buffer kit is quality material, the real highlight is the buffer it self. I have shot suppressors with this buffer on slo motion camera vs other buffets on the market and it is a noticeable difference in gas to the face. If you add one of the excellent griffin charging handles then it is even less. I have this paired with an adjustable gas block and once tuned there is 0 gas to the face.

    Fantastic System!

    Published by Garrett on 14th Feb 2022

    This stock mounting kit is by the far the best on the market! The thick end plate makes installation easy and the SOB actually makes a difference when running suppressors! Especially on SBRs!

    Smooth as silk

    Published by Unknown on 22nd Apr 2020

    This system is so smooth. Makes recoil lighter for follow up shots, and charging is super smooth. Worth every penny. I replaced a H2 on a 12.5” AR15. Noticeable difference.
