I am looking to build two SBR uppers, one a 7.5" 5.56 barrel and the second one I want to look identical in length, but I want to have a dedicated 22lr barrel (from Spikes Tac) cut down.
I am looking for the barrel length on the 22lr barrel so that I can fill out my SBR application, and I am also interested in knowing the dimensions that stack up to give me the OAL of the 22lr barrel. Specifically the distance from the Barrel Extension Shoulder to the back of the chamber on the dedicated 22lr barrel, and then the distance from the Barrel Extension Shoulder to the muzzle on the 7.5" barrel. I have a call into Spikes but I haven't heard back yet, will call tomorrow they are good guys, but I plan to go to see my sheriff tomorrow, since it is my only day off this week and next, wanted to see if anyone here can get dimensions for me. And for some pictures, in case any of that was confusing, please post inches, THANKS
