If I buy this kit does it come with everything besides the stripped lower?
Mckay B on Apr 13, 2018
BEST ANSWER: Everything except a rear sight, lower, and mag.
Does the kit come with all parts to build a working carbine? Does it include instructions on putting everything together?
Obsydian on Apr 13, 2018
BEST ANSWER: You would still need a stripped lower receiver and a magazine. I can't say if there are instructions, but basically you would be assembling the parts on the lower receiver, buttstock and grip. The upper is complete so you would just attach to the upper with the takedown and pivot pins. I suggest you google to see what's involved to make sure you have the necessary equipment. It's not hard, but if it's your first build, just take your time.
Can this be shipped to my home ?
wade b on Apr 15, 2018
BEST ANSWER: If your state has restrictions PSA may not be able to ship ship. If you go through the purchase process and it doesn't allow you to send to your home it may have you send to an FFL or not at all. PSA Customer Service is very good with this type of information. I live in 'KALIFORNISTAN' and PSA is very up to date on individual state laws. Good Luck.
can this kit ship to new jersey?
PAUL k on Apr 12, 2018
BEST ANSWER: It has been common for magazine to seat tightly if they are filled to full capacity, try loading with 1 less round than max. It can also be an issue of to type of magazine. Usually polymers are a little tighter fit. It could also be with material lower is made from.
Does this come with a magazine?

what rear sight is recommended? Do the flip ups work well with the front sight on the gun?
Weston B on Aug 2, 2018
BEST ANSWER: It's a standard AR15 front sight, so any AR 15 rear sight will work, either flip up or carry handle. It will also work with scope or red dot.
Can you remove the front iron sight?
Isaac R on Feb 19, 2019
BEST ANSWER: You can, however it contains the front gas block, and the plate behind it retains the front of the hand guard. Also the muzzle device will need to come off (you could grind the factory sight in half to remove but would still need to remove flash hider to nstall a new gas block). Alternatively, you can simply cut the sight down below the line of sight if you are worried about co-witness on a low mounted scope.
Is the handguard the standard 7 inches?
Josh R on Jul 12, 2018
Is this a complete set or just an upper?
Cody B on Mar 1, 2019
BEST ANSWER: It is a complete kit. Just add a striped lower and you have a good entry level rifle.
Does this kit come with the rear flip up sight?
Brody on Jul 6, 2018
Has anyone had trouble with inserting a loaded magazine? Sometimes I have to exert more than nornal force to get a loaded magazine to seat.
Gerald W on Apr 24, 2018
BEST ANSWER: sounds like a lower problem,are you using plastic mags or metal , metal seems to work the best , hope this info helps out.
Where would i buy the stripped lower?
Ramon A on Aug 26, 2018
BEST ANSWER: You can buy several different stripped lowers from PSA. They do require that they are sent through a FFL. The stripped lowers are treated the same as any rifle purchase. Stripped lowers do have a serial number attached to them.
Would your Christmas stripped lower work well with this kit?
pacnwjim on Dec 19, 2018
BEST ANSWER: It sure would, and with a little time (maybe an hour) you would have a great carbine
Is this the complete gun do I have to buy anything else ?
Walter M on Nov 16, 2018
BEST ANSWER: You will need to purchase a Lower, which is the part that accepts the magazine. You would of course need to purchase magazines and ammunition and any accessories. The Lower is the part that has the serial number which requires the NICS check. I purchased mine locally and the entire assembly took about 4 hours. Excellent kit.
Does the lower build kit come with an extra detent and spring?
Colin on Jul 6, 2018
BEST ANSWER: Yes, unless you lose all three they sent. I believe they send two for the front takedown pin and one for the rear takedown pin. Two for the front because it's the more difficult one to install. Both front and rear springs are the same
Can .223 be fired out of this rifle?
John M on Jul 21, 2018
BEST ANSWER: Yes, this will fire both 5.56 and .223
Is the handguard removable/replaceable? Could I swap it out for an M-Lok grip?
Mister on Jun 21, 2019
BEST ANSWER: The short answer is NO, with the fixed sight on this barrel, this configuration will only accept a drop in quad rail. You could find one but you are out of luck with free float handguards.
Is this semi or auto?
Cody B on Mar 1, 2019
BEST ANSWER: Semi only, There are no ar-15 kits on the market with FA FCG already included.
Will this fit an AM 15 striped lower?
Justin T on Feb 23, 2019
BEST ANSWER: I've used AR15 gun kits from PSA for a few stripped lowers that were other than PSA. Given that the AR15 platform is a MilSpec platform, any stripped lower should work fine. All of the builds that I've done with PSA components have matched up perfectly with the stripped lowers from other manufacturers. I've never been disappointed with what PSA has sent me. What I just wrote doesn't necessarily apply to the AR10 platform.
What optic/iron would fit this best?
Isaac R on Feb 20, 2019
BEST ANSWER: I use a magpul Mbus rear sight. But you can mount any optic and it will either co witness with the front sight post or it will see past/through the front sight post because the objective lense is so close. I have a fixed 10x40 bushnell scope on mine with no issues.
Will this work with a 5D tactical lower?
mojorisin on Jun 29, 2018
BEST ANSWER: As long as your receiver is compatible with mill spec. Refer to your receiver specs.
Is there a way to put a rail on the bottom of the gun for a flashlight/fore grip?
Isaac R on Feb 22, 2019
BEST ANSWER: Yes, just buy a picatinny rail segment, attach it to the handguard, then attach your prefered foregrip to that.
Will the front site interfere with Red Dot sight?
Dennis B on Sep 1, 2018
BEST ANSWER: Nope. And you can use a flip up rear sight through your red dot
How difficult is it to change out standard hand guard for a free float say an M-LOK?
Tom C on Jul 21, 2018
BEST ANSWER: That really depends on your skill level, mechanical and thinking abilities as well as what tools you have available. For me, i have done it SEVERAL HUNDRED times, so its very easy, 5min. For you ? Only you can answer that.
Does this kit have heat shields in the forearm pieces? If it has shields, are the shields single or double, top and bottom?
Snake on Jul 14, 2018
BEST ANSWER: Yes they have the heat shields. Both top and bottom. Single layer each.
Can I mount a bi-pod to this hand guard?
Drake S on Feb 12, 2019
BEST ANSWER: Not to the hand guard. There is no rail on the top or bottom of this hand guard. You could mount a bi-pod that clamps onto the barrel as an option.
Is the muzzle pinned and welded?
Nicolas H on Dec 18, 2018
BEST ANSWER: No, it is not.

PSA is the only way to go.
Let me start by saying that this is my 3rd build from PSA so you know what I think already. I'm a loyal PSA customer. I bought the 20" premium kit years ago and have put 4000 rnds through it with no malfunctions, then I built a 10.5 pistol kit and have put over 500 rnds through it with no malfunctions and since I haven't built an m4 I purchased the kit and put it together and gave it as a gift to my daughters husband. He has never owned and ar-15 style carbine. He absolutely loves it. We took it out and zeroed it and ran 100 rnds through it and guess what, no malfunctions. I have never had a single issue with anything I've purchased from PSA. Thank you PSA.

This build kit is affordable and a great start for someone who is interested in building their own.
I always wanted an AR 15 but didnt want to spend several hundred dollars for one. A buddy of mine suggested that I build my own and recommended PSA.
My first build.  Thanks PSA
