Sorry to ressurect an old thread...
But I have a flash hider coming in today and was planning on just using an armorer's wrench. I've been anxiously awaiting this sucker and REALLY don't want to wait on an upper receiver block/barrel clamp, though I'll buy them soon as well. Theoretically, If I were strong enough to hold the barrel in my hand right below the bridcage and use a wrench to remove it without twisting the rifle around, then wouldn't that sorta be the same as a barrel vise?? I have like mega-popeye-overdeveloped forearms and grip strength... I don't think it would hurt anything since the barrel wouldn't be moving, and I wouldn't be supporting the rifle by the stock any other part. Could someone please lend their expert advise? I think I hear the UPS man ringing... :big_boss:
