May try an AFG instead. After some research I ordered the MCARBO Kydex Cheek Rest Recoil Pad and Slip-on KSG Recoil Pad and a Hi-Tech Howitzer70 Muzzle Brake. Going to try S&B 2-3/4 #4 buckshot and see how it goes.
Never mind. Getting the Midwest Industries KSG mount with handstop and M-LOK slots. I don't like the feel of an AFG or VFG on my AR, so guessing I won't on the KSG. Don't want to add anything that could beat on my hand. And I like the larger stop on this MI part.
