Assembled Matrix Arms Delta RMR DLC Slide for Glock 17 Gen 3

The matrix arms delta rmr dlc slide for Glock 17 Gen 3 dominates every build list for a reason. First, we machine it from 17-4 stainless. Then we cut a true direct-mount RMR pattern—no plates, no nonsense. After that, we finish it in deep black diamond-like carbon for extreme wear resistance.

Next, you choose flush or threaded match-grade barrel. Finally, we install every internal, test-fire it, and ship the same day. Consequently, the second your matrix arms delta rmr dlc slide lands, you simply drop it on your Gen 3 or Polymer80 frame and go punish steel.

Aggressive front and rear Delta serrations, lightened side windows, and that armor-grade DLC finish laugh at holster wear. Same-day unmarked shipping. No FFL, no wait.
