I recently completed my AR build, using the stripped lower I bought from Palmetto State Armory several months ago during one of their periodic sales. I put her together last week, and got a chance to do a little shooting over the weekend.
The upper is what PSA sells as their PSA 20" 5.56 1/7 CMV Chrome-lined MP HPT Upper. The barrel is gov't-profile, and is made for PSA by FN. It has 1/7 twist, chrome lining, and is magnetic particle inspected and high pressure tested. The upper has M-4 feed ramps, even though it is a rifle length barrel/gas system... I guess can't hurt! I ordered it with Magpul MOE rifle-length handguards in flat dark earth. The upper came in a cardboard foam-lined rifle case with the PSA logo on it.
The stock is a Magpul CTR, on a PSA 6-position buffer tube kit. The lower parts kit is what PSA sells as the Palmetto State Armory Gen 2 MOE LPK, which is their standard LPK with a Magpul MOE grip and winter trigger guard.
The rear sight is a KAC 2-600m model I have had for a while (which I love). The sling is just a GI leather sling I had sitting around. I will eventually mount a 2-point tactical sling, as soon as I order some mounting hardware for the handguard. I also ordred 7 D&H mags in FDE from PSA along with everything else. They had the best price I have seen on them, at $11.99 each. They have Magpul followers, and floorplates that have PSA's logo on them.
According to my scale, the rifle weighs 7 lbs. unloaded. It balances quite nicely with the gov't-profile barrel. I like the collapsible stock on the 20" rifle. However, I wish the stock adjusted a little longer. At maximum length, the charging handle is at the base of my nose, up against my face, instead of at the tip of my nose when I am all turkey-necked out on it. The total cost of putting the rifle together, including shipping and the $10 transfer fee on the lower, was $753.79.
I took it to the range over the weekend, and zeroed it at 25m. The front sight had to come down quite a bit to get it to zero... I made 7 clicks down, which nearly bottomed it out. The front sight was also very stiff to adjust. It wouldn't move with just a bullet tip... I had to turn it with needle nose pliers. I had to take the rear sight 14 clicks right of center.
I was very satisfied with the way the rifle shot, and with its accuracy. I included a pic of my zeroing target. All groups were shot from prone with a sling at 25m, with Winchester 55 grain ammo. I experienced no malfunctions.
Here are the pics:
Nothing wrong with having both!
I will probably get either a 14.5" carbine length gas or a 16" mid length gas myself before too long (I still have to decide!).
I'll probably run the 20" with a 1-4x, and the carbine with an Aimpoint.
Gotta keep telling myself (Dissipator is just as good, Dissipator is just as good)
My 20" got parted out and is being redone as a Dissipator. That is one sweet rifle!
