Does anyone out there have recent experience with either the Tactical Innovations T15 or T15BDX (NOT TAC15) lowers? I have been contemplating buying one or the other for a new build. Unfortunately I have not had much luck in searching the site for information. I found several posts from members who have mentioned using them but no detailed information. If anyone has used either and could give me their impressions, reports of any issues, and possibly some better pictures than their website, I would be grateful.
