I've got a brand new Surefire HK94-MP5 forend, with the on/off rocker F option. The box was opened but everything is included, manual/box/complete weaponslight etc. $185 shipped in the CONUS, paypal and MOs accepted.
With a little modification these 628 forends will fit on Mosberg 20 ga. shotguns, AK style rifles etc. Email me for pics of both the NIB forend and a 628 on a Ak47.
