Mainly an H2. Have a CAR buffer for my Grendel on an 18 inch setup and notice a little bit of recoil. Have read multiple times to switch out to an H2 with this setup. I have heard good things about the Spikes units due to being loaded wiht powder for weight. Sounds like it would be similiar to a Dead Blow hammer. Last I looked they were out of stock I thought. Also with that thought would I be better to step up to a heavier unit or will and H2 equivalent be good.
Thanks
