Here we have a practically new Matrix M4 GBBR. It has minimal wear and was never fielded. I bought it right before covid lockdown and never saw the light of day since. Willing to negotiate price until the seller and buyer are satisfied. It does have some minor wear and tear as shown on the last 2 pictures which still functions despite these conditions. The magazine has a minor leak due to inactivity. A good lube should fix that. Optic is included and it has a full metal body and rails. Any other questions please feel free to messege me. Do not buy from hopup. Please use PayPal or cashapp. Free shipping on me.
