Is it possible to attach 5.5”+ suppressor to this kit and then put regular buttstock on and be legal?
M G on Jun 8, 2018
BEST ANSWER: NO, and the reason is.. a 10.5" bbl is not long enough, you need a 11.5" bbl to go with the 5.5" FH due to .5" thread overlap between the barrel and FH, you would only be at 15" when completed, which is still SBR / Pistol length. would need to be permanently attached by blind pin and/or welding, not silver soldering.

Acurate pistol
I've had this kit for about six months now. Put it together with an Anderson lower and MATECH rear site. Front site is positioned straight. I like the Nitride finish. No malfunctions even with low powered steel cased ammo. Shooting prone unsupported and using a two point sling pulled tight will keep my groups in the 2" range with cheap Tula 55 grain. Haven't tried heavier grain bullets yet.

Excellent kit!
I ordered this kit to do a build on an Anderson lower I had sitting in my safe. It arrived quickly and was excellent quality for the price. Mine came with a bayonet lug on the front which was an added surprise. All of the parts for the lower build kit went in quickly and easily just like my past builds. Total I'm only in to this rifle for about $500 with the kit the lower match grade rear sight and a brace. This is my 4th PSA rifle and I would highly recommend this (or any PSA rifles or parts) to anyone who wants to do a cheap quality build. I'll update this after I run the rifle through it's paces.

Awesome deal for the money!
Ordered on a Thursday had it on Monday! Fastest I've had from PSA! For the price you can't beat this! Let's face it of you are getting this you're just not wanting to pay the 200 dollar tax stamp for having a short barreled rifle! I mean to be frank about it! This is the way to go just get a sig brace or a thordsen forearm brace and a good optic you are good to go! Thanks PSA you always have to good deals for the quality!

I ordered received and built this kit! I assembled it on an Anderson lower. The only problem I encountered was the pistol grip screw hole on the Anderson lower wasn't tapped all the way. I had to add a couple of washers to the supplied screw to tighten it down. Anderson's fault not the PSA kit! I will be buying more!

Great pistol upper
I bought this kit and a stripped lower to make an Ar pistol. I had heard a number of negative reviews about the shorter barrels especially those with the pistol length gas tube. The carbine length gas tube was what made me lean towards this particular kit. I was a little apprehensive about firing this once I had it completed given the arthritis in my wrist. Thankfully the recoil was incredibly light even more so than a 9mm pistol. I have not experienced any malfunctions during my outing with the build. I really like the quality to price point that PSA offers and two of my three AR platforms have come from here.

A lot of bang for your buck!
As usual this is quality PSA product. I built the rifle on a stripped Anderson lower test fired it zeroed it loved it! The melonite finish on and in the barrel is great and cleaning was a breeze. I love the look of the front sight on the short 10" barrel and the flutes in the receiver extension. One word to PSA tho you need list that the kit comes with a complete HP/MPI laser engraved PSA Bolt carrier group. I see it pictured but it isn't mentioned in the text. To me that adds a lot of value to the kit vs. a generic no name BCG.

This would make a great home defense or truck gun. You can rely on it to work when needed but not have a lot of money tied up in it to worry if it sees abuse or neglect.

Super Fast Shipping Great Parts
I ordered this kit on a Sunday it arrived the following Thursday. Fit and finish was great and the upper black blended and fit with my Anderson lower like it was made to. This was my first AR build and I was a little apprehensive about it. I followed a guide online and had it set up in less than an hour the only special tools I needed was a roll pin punch set from my local hardware store. After reading some critiques about long shipping times with this company I was prepared to wait a little bit for such a good price but that was not the case on this order. I was pleasantly surprised when I received the tracking number the day after ordering. Palmetto gained a loyal customer with this one and I can't wait to build another one. Thanks!
