the magical brown truck just showed up about 10 min ago with my new Noveske 18" spr upper XD that damn thing is beautiful. once my IOR 2-12x32 comes in the build will be almost complete. i say almost cause i need to take the ugly ass Smith Ent. vortex off of it and put on an AAC spr/m4 mount. any help with getting the damn thing off would be appriciated. note: the FH is not spot welded on, and i don't have acces to a gun vise...... is there any hope for a DIY with this thing?
