Looking to setup a gun in the RZR or truck that's compact with the suppressor for small gophers but I'm curious is there anything out there that shoots AR barrels & how accurate can I guy get a auto bullpup?? The reason I would like to run a AR barrel is I run a 20 Practical and match barrels. Would like to get it close to my AR's that shoot .75 MOA pretty easy. Any help would be great Thanks.
