AR Pistol build

[Kruel J]

I've got the lower done. Now I'm looking at uppers. I already had a Radical 7.5" that I ended up selling because I didn't care for the way they mounted the gas block. Basically It gave me grief and kept loosening. The guy I sold it to said he was going to tack it in place.

Anyway, I'm looking at this one possibly, but it's even shorter at 7":
PSA 7" Pistol Length 5.56 NATO 1/7 Nitride 6" Keymod Upper - Without BCG or Charging Handle - 508028

Any experience or recommendations? I'm not looking at spending a fortune either.

Hardened arms has a good deal on a 7.5" complete upper assy, among other pistol uppers.

No affiliation with the company. No expert either but just really like my HA 16" rifle upper and I don't see much talk on forums about Hardened Arms products. Great customer service too.

Not wanting to build your own?
The upper is a lot easier than the lower.

Aero has them in stock but for $359!

A buddy of mine has this exact upper on a polymer lower. the pistol is well balanced and very easy to point shoot without any sights. I am planning on grabbing one of these for myself.

I have a PSA 7½" upper that looks a lot like that one and it has run great for me. No gas block issues, no cycling issues, just bangity-bang-bang. Never tried that Hardened Arms one but it looks nice and it might be more comfortable. Not that I find mine uncomfortable, just saying.

It's really pointy shooty with a metal lower and a Shockwave Blade too. They're $50 at Rainier Arms. The buffer tube with detents for the set screw (I recommend it) is only $20 more.

Kind of in the same boat. Not in a hurry on buying one - but still can't really decide what upper to throw on it. I'm leaning towards an 8.5 or 10 inch upper to get more poop out of the 5.56 round, but if the HPA passes first, I may go with a 7.5 and then put a can on it.

Not so sure that the upper is easier than building a lower - the lower requires no special tools. The upper requires a vice, torque wrench, and a receiver block to properly assemble. There may be fewer components, but there's more "stuff" required to assemble one. I assembled my last two uppers using a small hammer, punch, and a screw driver. On my coffee table in my living room.

Great deal, thanks! Just ordered it!!

To me, a pistol 5.56 just does not make sense. It neuters the round so much and the over blast is crazy. I would go with one in .300bo or in 9mm. Palmetto has good deals, as does radical firearms. I ordered a pistol upper from karris guns and was happy with the quality.

 

[Kruel J]

Well, to each their own. A 55gr round traveling at 1700-1900 FPS is quite effective for the intended use of an AR pistol. I wouldn't call that neutered.

Not only that, they are just really stinkin fun!!

They sure are. Get some of that cheap Tula steel cased ammo. You get a basketball sized flame out of a 7" or 8" barrel with that stuff.

If the bullets don't kill the bastard, you can at least set him on fire and permanently disfigure him

And temporarily blind and deafen him too.

And my newest build should do even better!

I was a big timer today. I finally shot my 5.56/11-1/2" pistol, with a VG6 Titanium Epsilon, today. Yep, I pulled the trigger four times (not zeroed yet) and that thing belched like a dragon with indigestion. And sounded like a 50cal. LOL!!

Linear compensators on all of my AR pistols.

What linear compensators do you use? I have been looking at this:
SAA 5.56mm Dragon's Head Muzzle Brake / Linear Compensator - GEN II

and am wondering if anyone knows whether it is worth a damn.
