TACCOM AR22 testing…..new upper and a 50 round drum

www.taccom3g.com
We just assembled this new upper and came to the range…..first run!! 40gr blazer ammo. Black Dog Drum set up for the M+P 1522. We are using a .090” shim on the front of the mag well to snug up the smaller magazines. We can also run standard black dog mags for the AR22 with no shims.
