So this is my first Grendel upper build, I have a 16 inch group buy barrel and bolt, a Gibbz side charging upper, Adams Arms piston system with light weight boron carrier and a Yankee Hill M-Lok hand guard. I also swapped out the buffer system in the lower with a JP Enterprises captured spring system.
Now, the things I still need, firing pin. Does it matter which one I get?????? And a Muzzle break, Any recommendations as which muzzle break to get for the Grendel??
I am also considering the DOLOS quick change barrel system, so I can switch from the 16 inch barrel to a 20 inch. Anyone have any experience with this?
