This thread is going to seem a little chopped up, I am posting at a few forums.... and In order to keep my sanity... I will cut and paste info as I post, while still answering specific questions at all the various forums....
Let me start out by saying this thread is a "This helped fix my concerns and issues with my PSA Gen II Nitrated, Nickel Boron BCG 18" Carbine."
The thread is not a negative post about PSA in any way.... so if someone just wants to complain, please leave it out of here... this thread is about making your heck of a deal rifle run smoother.
I am posting this to show what made mine run MUCH smoother... I am going to the range today for its first firing.
I will post the results later... I have a lot of stuff to try and get done at the range today.
So it finally got here... and I wasn't kidding about PSA building as they get orders !!
Also.... as shipped, this is beyond a doubt, the most oil free rifle ever. Everything is bone dry... the best part about that is it makes finding any rough finish / binding parts easier. That is not to say the finish sucks, as a matter of fact, the finish is as good as any of my AR's , Colt , BCM, Rainer Arms, etc.
It just needs a little polishing in spots, and OIL... did I mention the lack of oil ? Lol
Just as a reference ...Oil used is ALG Go-Juice.
As for the polishing... in the past I have found a little burnishing, on various parts can greatly improve the "feel" ... and the PA10 was no exception.
0000 Steel wool , the finest commonly available ( won't even scratch glass ) is what I use.
When I say a little burnishing, I mean about a minutes worth.
So far, parts minimally polished that show drastic noticeable improvement on the lower.
The inside of the buffer tube... it was just rough and gummy (?)... after a spin down the buffer tube with a 0000 steel wool wrapped 12 gauge bore brush, it is much improved, then after a proper OILING on the interior of the tube and on the buffer and spring, it is nice and smooth.
The disassembly pins.... burnished and lubed.. improved smoothness.
Burnished the outside of the buffer tube as well.... much smoother.
Now for the most interesting polished / burnished "part".... the magwell.
One of the first things I tried was the mag drop and insertion...Magpul 10,20,25, and 25 M118 wouldn't drop free.. loaded or not loaded.
A few minutes of burnishing the interior of the magwell, with little effort given to being through... resulted in all Magpuls dropping free, unloaded and loaded.
Worked so well that I don't even feel the need to oil the magwell.............. just kidding, gave it a coat simply because it is bone dry.
Again... very little effort to polish up working surfaces only... maybe 3 minutes.
I should add, the PSA rubbery hand grip is pretty dang nice.
Trigger is typical "MilSpec gritty"... I am going to try the USGI paracord trigger job on it because I want to see if it works. I will measure , with my cheap RCBS trigger pull gauge, the before and after weights.
Paracord AR-15 Trigger Job
Straight out of the box, its heft is ok... I was expecting more heft / weight, given PSA's 10.4lb listing.... actual weight... 8 1/4lbs bone stock.
The only way I could make it close to the advertised 10.4lbs, was by adding a fully loaded 25rd Magpul and the owners manual and magwell security lock.
OAL as delivered....collapsed, 37 1/8ish"... extended 40 1/2ish"
I will be adding info as I get time... but so far I feel confident I will like this PA10.
