Stribog SP9 / colt mag adapter sleeve

Colt 9mm magazine adapter sleeve for Stribog SP9.  Allows use of Colt style 9mm magainzes with your Stribog.  Inserts from above the magwell and held in place when SP9 is closed up.  Works with last round bolt stop and has an internal magazine stop so the bolt stop won't be damaged by magazine over-insertion while SP9 is opened.

Built in feed ramps nudge the rounds inward and up just enough to hit the barrel feed ramp correctly.  Works for rounds with large, flat bullets with a large meplat or very little taper.

Works best with C Products Duramag magazines, or with Metalform / PSA magazines with my replacement follower and maybe a Wolf Xtra power spring for better reliability.
