Recently bought many items including the gas thru adjustable stock with quick connect. Also purchased a couple of your box mags for a mrx and a tmc marker. These box mags are aweso... view moreme and I can’t say enough about them from their sleek low profile design and great feeding system I think you guys hit a home run with the box mags so much so I just placed another order today for my 3rd box mag for another mrx. When your shooting over obstacles all you see is clearing the barrel some flip up sights and a little flash of the goggles looking at you lol. Low profile is the best once that gravity hopper is out of the way. Again a truly great product and I couldn’t be happier thanks for everything. view less
