Found locally a Sabre XR 15 lower for 110.00 plus tax. I am seriously debating building an AR so is this a good start? From what I have seen online it looks like a good price. 
buy it. sabre defense lowers are one of the best finished lowers i’ve found + 110.00 is a good price.
If you dont want it I will take it. I have 2 of these, one of them now registered as a SBR lower. Both have excellent fit and finish, and both drop PMAGs free.
I have two of those. It doesn’t get any better than Sabre IMO.
Just did a build on one, I’m pretty happy with it, only issue was, I had to ream the selector detent channel just a little bit. Jeff
Dude, if you don’t want it, at least point us in the right direction.
I have two of them, purchased in 2007, and I built a complete lower for my Super SAM rifle using one. No complaints at all.
How did you ream it? My selector detent hole is off as well. I am kinda bummed out.
Just touched it with the next larger size drill bit.
I have some thought the hole is on the smaller end of the spec and my detent was on the large side from my CMMG LPK. I checked it before I reamed it with a couple other detents and they were not as snug as the one from the CMMG kit, but they were still tighter than I preferred.
But the fix was easy and should presnt no future issues.
