I like to use these on all my rifle which take AICS pattern mags. Look and fit are excellent and save sticking a flag type ECi up the pipe.
Downloaded the file and the print/fitment was top notch!
Fits great in my ARC chassis and works good.
I printed mine on my ender 3 with overture PLA. It's snug in my XLR Envy JV and does exactly what it's supposed to.
Well first things first I love the fact that a company that sells a product is okay with giving a print file away this is amazing and because of this I will be purchasing more items from you
