bullitt3989I have a matador arms Mat9k self contained 9mm upper. This is the direct blowback model. I have a sylvan arms 9mm lower receiver mag block that converts receiver to Glock mags and it includes a buffer tube railed adaptor to allow you to run a folding stock. The upper is all self contained so does not require a buffer tube. I have a Mat9k sd handguard I ordered but hasn’t shown up yet I will include. I was able to grab a stribog 45acp model and this needs a new home. Message for anymore photos or info 4235714846
