The Matrix Arms Delta RMR slide is the one builders fight over. First, we start with premium 17-4 stainless. Then we mill a perfect direct-mount RMR cut—no plates needed. After that, we coat it in black diamond-like carbon (DLC) for insane durability.
Next, you pick either a threaded or flush match-grade barrel. Finally, we install every internal, test-fire it, and ship the same day. As a result, the second this fully assembled Delta slide arrives, you simply drop it on your Gen 3 or Polymer80 frame and go run it hard.
Aggressive Delta serrations, deep side windows, and that armor-tough DLC finish laugh at holster wear. Consequently, you get same-day unmarked shipping, no FFL, and no waiting.
