Is there a vendor selling mini barrels for a semi-carbine or pistol? I would like to mount a Whitt Machine SME brake/shroud muzzle device to a mini pistol with either a clamp-on adapter or find an adapter that would replace the barrel nut, if that exists, to attach a 5/8/-4 device. I would also like to know if anyone has tested the SME on their Uzi pistol or carbine.
