I had contacted PSA a couple months ago when they were running a sale on upper/barrel assemblies, wanting to step up to a 20" barrel to make a DPMS LR308 more of an "LR" rifle. To their credit, PSA warned me off of the idea. They acted like it was a cosmetic issue at first, but when pressed, were very non-encouraging over the entire compatibility equation.
LoL, I think you scared the Devil out of them.
I got the headspace checked first thing, per Aero's advice
OMM, not directed at you, for others this is "Fundamental", Period!
So everyone knows this , why do I comment on this? Many don't have the proper gauge~s to check HS for 308 or even other platforms they run.
Having stated that, a 308 round ( with firing pin removed ) is NOT A Headspace Gauge! Yes, I've witnessed it.
Another situation is , HS must be OK because she shoots fine.
Really??????
I am fortunate to have the proper gauges. If one doesn't have the proper gauge, find a set or someone ~ place that does.
IMHO, the BCG & Barrel, Barrel Extension better be "Soul Mates" in that it locks up and Headspaces properly. I've had TWO 308 BCG issues, one being TOO Much Headspace in which the Bolt Locking Lugs were .311" and suppose to be .318" ~ .319" . The other BCG issue had to do with the Gas Ring Bore in the Carrier. The dealer made both good, No Problem.
Buyer beware. I think I lucked out in getting something that works well enough, but has some cosmetic deficiencies.
+1
Again, not directed to you, OMM,,,,
Yes buyer beware and if you're going to piece meal a 308 rig together to owe it to yourself to understand it better than the ave interested shooter.
I fully agree with Cross in that a "Turn Key " DPMS or other budget LR-308 will get you in the game and you can go from there.
I also understand that many wanting to get into LR-308 fun at a budget level start "Experiencing a High Level of Anxiety" because from what they read and talk to others, they believe they need to immediately buy a "Drop in Trigger" to obtain good results, etc.
Not SO!
For me, faced with a choice to Eat for a Week or buy a drop in trigger, I am eating for a week.
IMHO to start with, one needs a good ~ decent barrel with a BCG that properly MATE and this means if you want to run it all , Nato & Commercial ammo, your overall performance my suffer because of a looser HS. No Free Lunch.
Safe Shooting
