Considering my first AR build with this kit. Any recommendation for a decent lower that I should use? Thx.
Ed C. on May 15, 2018
BEST ANSWER: Honestly most lowers are about the same as long as we're talking mil-spec lowers. This is because there are only a few companies that make lowers (they brand them out for other companies). I would just stay away from the polymer lowers personally. I'd recommend Spikes Tactical lower receivers. They look cool and Spikes is a great company that stands behind their products 100%.
Does the upper come totally assembled and if so is head spacing required?
Ungrateful C on Jun 25, 2019
BEST ANSWER: Yes, the upper is completely assembled and headspacing is not REQUIRED (they headspace the bolt that's in the kit to it). is it a good idea to check headspacing on an assembled upper? sure. But it's not REQUIRED as 99.999% of the time it's never needed.
Is this a heavy profile barrel ?
Roberto S on May 2, 2018
BEST ANSWER: The description states that it's A2 profile, so it should be about .750" from the gas block forward and about .625" underneath the handguards / rail. Looking at the photo on a big monitor, it does appear to be thinner under the rail.
How does this gun compare to M&P sport by S&W? Pretty new to ARs, just want to make sure I'm getting quality.
big johnson on Jul 12, 2019
BEST ANSWER: I would take this over the M&P sport any day.
What is the difference between a carbine length gas system and he mid length gas system?
Thereckshop on May 27, 2019
BEST ANSWER: A mid length gas tube is a little longer than a Carbine length gas tube, resulting in a gas system that uses a higher volume of gas to chamber another round. Someone correct me if I’m inaccurate, but this should result in less recoil and is easier on your internals.
If one was to purchase this kit; what else would be needed to complete the whole thing? A striped lower
Kevin G on Jul 31, 2019
BEST ANSWER: Yep, that's all you'd need. I did two of these on two completely empty, stripped lowers, and couldn't be happier with them. Everything fit perfectly, and the rifles perform great.
Whats all needed to have a complete kit? A rifle kit and a striped lower. Am I missing anything?

PSA AR15 American Flag Engraved Stripped Lower - 7779528
PSA AR15 American Flag Engraved Stripped Lower - 7779528
BEST ANSWER: Those two kits will give you a fully functioning rifle. It does not come with a magazine, so if you don’t already have a 556 mag you’ll need to buy one of those as well. That’s it though.
Looking to build my first rifle. Will this stripped lower pair well with this Kit im looking to order? PSA 16" CHF A2 Mid-Length 5.56 NATO 1/7 13.5" Lightweight M-Lok MOE EPT Rifle Kit . I don't want to pull the trigger on this build until I know for sure I have the right stripped lower. Im also going to add the nickle boron bcg as well, And a premium charge handle, after I get this built. I got bills so i have to do this is steps. Thanks in advance.

BEST ANSWER: Mine said 4.1 on my scale
Does this weapon make a full auto rifle or can it be configured as is for semi-auto?
Thereckshop on May 27, 2019
BEST ANSWER: This isn't a weapon. It's an upper receiver and lower build kit. If you put this upper on a full auto lower, then it will work as such. But since you're asking this, I'm assuming you don't have one. So semi it will be. The Full Auto you see in the description only applies to the Bolt Carrier. This means it would work with a burst or auto sear. Semiautomatic functionality is the result if you put it on a stripped lower you can buy today.
Is the barrel dimpled?
Adam G on Nov 21, 2019
The Only markings on the bolt are 158. Is this bolt HPI/MPT?
Thomas N. on May 21, 2019
BEST ANSWER: You bought this kit for the superior FN made CHF barrel and the enhanced trigger. Don’t worry about the bolt. It’ll work fine.
Does the upper come fully assembled? If so is head spacing required?
Ungrateful C on Jun 25, 2019
Is the barrel length 16” without the flash hider?
John P on May 12, 2019
BEST ANSWER: yes, all barrel lengths are measured before muzzle end is put on, unless it specifically states otherwise ( 14.5" barrel with pinned and welded muzzle end to make "x" amount of inches for total barrel length)

Best choice for Me
I have a AR-15 Varmint Hunter with stainless heavy bull barrel in .223 Rem. Decided I needed another upper to ad versatility. My son gave me your site. The selection is overwhelming. I watched your sales and had been narrowing down the complete uppers. Then one ad I seen Kit - 5165448203. Reading the specs on the CHF barrel is what sold me. A complete upper I can switch with 2 pins. A lower kit for spare parts that I can get a receiver for later on. The upper feels really good and is lite with the MagPull bus sights. Just what I was looking for. I did the fieldstrip, cleaned, and lubed where needed. Shot 10 rnds. at 25yds. to adjust the sights on zero. No issues. The upgraded trigger is fine for me. Accuracy is better than I expected for double chrome lined ,full auto spec barrel. With some handloads, factory loads test it could become my new varmint AR?? Site, ordering, shipping, Excellent. Thanks PSA Great job

Awesome rifle! Can’t beat the price!
My father and I bought PSA rifle kits to put together for Father’s Day. We had a great time putting them together. They really are like LEGOs for adults. This is the kit that I purchased. The rifle shoots great and i was shooting some pretty tight groups after sighting in. Only minor complaints were I wish this upper and my PSA PA-15 lower fit a little tighter together, and I also had to tighten down the handrail after shooting it for a while. I was wondering why I had to put the rear sight all the way to the right until I noticed the handrail had started moving as I was shooting.

Worth The Extra Expense For The FN Barrel
This was my first PSA AR build but I have several Colt AR-15's. Wanted a nice custom AR with the high barrel quality that I could customize and easily scope. The kit comes with everything but the stripped lower. I used an Anderson lower and the fit and finish match the upper nicely. Just got back from the range and was shooting .75" to 1.25" groups with a 1-4X Vortex at 100 yards with inexpensive Geco 55 grain FMJ ammo (See Photo). Can't wait to work up a few hand loads for this excellent rifle. Everything feels great. Love the MOE furniture. I will probably eventually upgrade the trigger but the PSA EPT one is very serviceable and smoother than any of my Colt rifles. Great job PSA. This kit is a winner!
Geco 55 grain FMJ Ammo at 100 yards.
Love the looks and feel of this AR.

Great Kit at a Wonderful Price Point 5.16.2019
Solid Upper! This is my first AR and first build. I have been reading, listening, and asking questions about AR style rifles for over 6 months. This kit came with everything except a stripped lower receiver. Everything was received in less than 5 business days from order. I was compelled to use Palmetto after their interview with Reed and JD on the AR-15 Podcast. Was very impressed how they are bettering themselves and their customer experience. Can not wait to built the rifle this weekend and show off the results. Very Excited!

Awesome Kit
This kit is the bee's knees. It comes with everything you need except the stripped lower. Mine is marked FN, HF, MP, 5.56. 1/7 on the barrel to let you know it is cold hammer forged and magnetic particle inspected. This kit has great specs and will get you a quality rifle on par with high end manufacturers like BCM, Spikes, and of course FN.

The FN barrel is great!! No issues so far. The upper could have been finished better inside. Not coated all the way.

Great kit
I used this kit to complete my first 80% build. Although this was my first build, it was far from my first AR. What I would have given to have had a weapon this nice back when I was issued my A1. I hope to get many years of life out of this one, and for the price, it was an outstanding value. Highly recommended.
