I’m looking to sell my Matrix M4 gas blow back rifle made by S&T. The rifle has a Western Arms gas system and includes the original mag and 3 extra. None of them leak and feed as they should, all together this set up may have seen 1000rds. The Keymod foregrip will be coming with the rifle. The $320 includes shipping and PayPal fees. I’m only getting rid of this because I have gotten a PTS Masada since getting this brand new 2 months ago. I may interested in swapping for a other gbb (not CO2)handguns (European makes like beretta, hk or sig), or sub guns (KWA MP9 or VZ Skorpion). I am still open to anything, I will only swap if you are local to AZ! Try shooting me a text for a faster response since it takes me 3 days before I can see a message on here 😂 (623)302-6828
