Home Forums Hunting & Shooting AR and Tactical Rifles 10.5" AR-15 5.56 Pistol

Well, I got my PSA pistol upper today, and completed the pistol build.

I got out to test fire it, and put a 40 yard zero on the irons. Sun went down on me, and I lost light quick.

JBM suggests a 40 yd zero should keep bullet path within about 2" of LOS out to about 230 yards with M855 at 2600 fps.

I gotta say. it was a lot of fun to shoot. I was sitting leaning against the truck tire, Just getting some 40 yard 5-shot groups to get a zero.




Feel free to share your AR pistol stuff here.

That is impressive as hell. May I be so bold and get a price check on the upper ?? Did it come with a BCG and charging handle ?

The upper was $219 shipped from Palmetto State Armory. BCG, CH, and Magpul handguards included. I added the rear sight.

Looks like that upper is now out of stock, but there are others here:

Good for you! Looks good!

You just might be surprised how much time this little guy spends with you.

Love mine.

I'm already feeling the love.

I'm probably going to add some type of optic. My eyes and bifocals just aren't cutting it anymore. I can't get a clear front post at all.

I'm thinking probably a 3X prism style from Primary Arms.



What kind of optic are any of you using on your AR pistols?

I can't imagine a Red Dot not being the right idea. I'll find out soon enough.

I was looking at the red dot option. The thing with most red dots is they don't appear to have a diopter adjustment.

Things I like about the Primary Arms prisms (have two already), they do have a diopter, and the reticle is etched, so it shows black if the battery is dead, or turned off. Of course the downside to the PA prism is the weight factor. Every option is a compromise of sorts.

Mine has a 1-4 Leupold VX-II.

Wife's has irons.

Third which I put together for the kids for plinking is mounted with a cheap red dot. So far all I've done with it it zero it. I'll probably throw together another lower for it and add a .22lr sub cal adapter over the holidays.

If I was looking at something from Primary arms for one, I'd consider one of their 1-6x or 1-8x's.

Of course, if money wasn't an issue I'd take Formidilosus recommendation and go with the Nightforce 1-8.

Load wise, the best I found for the PSA barrel was 53gr Nosler Varmageddon over a max load of TAC and CCI 450 primers.
5 shots just over an inch at 100 with the above 1-4 VX-II, but it never broke an inch.

Yeah a NF would be nice, but looking for something in the Primary Arms price range, $300 or so.


I have been considering the PA 1-6x24 as a possible. If one of those didn't work out on the shorty, I could migrate it to a carbine or rifle pretty easily..

sadly my eyes and red dot's don't go together anymore. Waiting on NF to release their NX8 with capped windage and elevation before I buy it, I have knocked SWFA 1-4 turrets off zero more than once pushing them behind a seat, or why even in the gun safe.

Checked the irons at 100 yards. Pretty close. 10 rounds off the bench. Fired them all in under 1 minute. Good enough for irons and a fuzzy front sight.

Shane, they've got them on sale now in gray color.

Price must be really good. Crashed the site.

Old eyes, iron sites, and milspec ammo,

No bad.

local dirt, thanks for the heads up.


antelope sniper, I was kind of surprised they all hit the black. I was just holdin' and squeezin'. I would imagine an optical sight would easily cut that group in half.



I probably need to adjust the impact up one click via the front sight. That should be about 1.75" at 100 yards on the carbine sight radius, and give the relatively flat 200 yard trajectory I'm looking for.

Just ordered an upper from PSA.

That looks like too much fun!!

It is a fun gun to shoot. I don't know what it is about it, the small size with the big boom, but no recoil to speak of.

This evening I ordered a Primary Arms 1-6x24 with the ACSS reticle for 5.56

This could be a fun little rig for well beyond 100 yards.

you may want to shoot heavier bullets.
