Yes; MaTen compatibility is SR25/Armalite/DPMS/Noveske. Barrel and bolt have to be the same. Yes this will be the gooder than better build. Not proper grammar, but oh well. I like quality stuff. Especially if its made right here in the U.S.A. I like to keep my money home, and support local businesses. I don't mind used parts, but with the barrel if it's truly 200 rounds that's a barrel break in. Money and ammo I don't have to spend. But on the other hand its used, not new, and if its a dud. I'm out the money. I like new stuff, I'm gonna go with a 1:10 Krieger if I can find one new. I have the local gunshop looking for a barrel and bcg. Quality/precision are key in this build. Kinda hoping somebody on here might have barrel to spare. But if not, I will find one on Gunbroker. Patience is key
