    PERFECT!!! Exactly what i needed to put my suppressor on an old Spanish FR8 rifle! Removed the old flash hider, tightened this adapter down, and now i can use my 30 cal suppressor, or a muzzle brake to tame down the recoil from the steel buttplate! Will fit any hk 91/cetme style barrel and make it easy to use aftermarket 5/8×24 brakes!

    Great quality. Best price anywhere. And its not an oversized chunk of pot metal like the cheap ebay adapters. I would definitely reccomend these adapters.

    Great quality and great value. Using these on H&K91 and a CETME to mount the popular muzzle brakes….now if Hughes would only manufacture a M15x1 to 1/2-28 I can use it for the HK93 and C93
