Service to add a rivet to almost any 20-40rd box mag, to reduce maximum mag capacity to 10 rounds for ban states.
Cannot pin drums.
Service is per-mag, only place this in your cart if you need mags pinned, and add as many pinning services as you have mags to pin.
Came in fast & the mags are really nice 2/2 with these mags so far will order more in the future
They do a great job of pinning the magazines for us citizens who are behind enemy lines in ban states!! God bless Texas
