Great magwell!
If you are running mags without other extendo boys amazing product! Unfortunately I am and could not find anything online as to if mine would work. Unfortunately they did not. The fit on the gun could not be better and would definitely recommend to anyone looking. For me I did the unthinkable and voided the warranty and used a Dremel to modify a bit and not it works great. If it fails that’s on me but I think it’ll hold up for as long as it would unmodified. Appreciate the great work SLR. Will definitely be getting more stuff from you guys. My extenders are strike industries +5 for anyone wondering
