So I just built a AR that I wanted to be set up for Tactical 3 G in the event that I every get off my *** and start going. I picked a 18" SPR barrel SS match 1/8 with rifle length gas. I have it all together now and the SPR is a touch heaver then I think I would want to use running around shooting a match. Question is how much would I be looking at to re-profile the barrel and what is the common profile for 3 G tactical class rifles? Generally I think I would be fine starting out humping a little extra weight but want to have an idea of what I am looking at down the road.
Thanks
