What lower receiver do I need to buy?
Logan M on Jun 24, 2018
BEST ANSWER: Logan, if you're asking that... you may need to do some more research on your own. There is more material available on The Google and The YouTube that will tell you everything you need to know about this. But to answer you question, EVERY AR15 stripped lower that is sold in the USA will work with this kit, ok? ALL of them will work.
is there a rear sight?
josh b on Apr 13, 2018
What's the length of the handguards? So I can buy a rail
Richard on Aug 29, 2018

Is this head space checked?
Semaj D on Nov 16, 2018

Does this need to be sent to an FFL?
Nicholas M on Dec 8, 2018
BEST ANSWER: No. I am a FFL and these components are not serailized. Only a lower receiver would need transfer through a FFL.
Is the front sight removable?
alexander m on Nov 26, 2018
BEST ANSWER: NO... sorta, you can NOT remove it quickly, and put it back . it IS removable by punching out the 2 roll pins at the bottom of the sight, and the 1 pin that holds the gas tube in place. then replace it with a new gas block. but if you are worried that the front sight will be in your way while looking thru a scope, don't worry it won't be a problem. you won't even notice it there. i own 8 AR's and all of them have the same fron't sight. (if it ain't broke don't fix it)
Will a bayonet fit on it properly?
Noah S on Jun 26, 2018
BEST ANSWER: Yes! My bayonet fits perfectly.
What is needed to finish this build?
Mickey B on Dec 2, 2018

Will this kit also work for a.308??
DAVID N on Nov 29, 2018
BEST ANSWER: No - I do not believe this kit will work for a 308 platform - This is an AR 15 in 5.56 / 223 platform. If you want a 308 platform you'll have to buy an AR 10 kit.. which will be a little more costly but still the same amount of fun and reliability
Since this isn’t a complete rifle, does this kit need to be registered yet or once it’s actually assembled with the lower ?
JR C on Nov 21, 2018
BEST ANSWER: Neither. The only part of an AR build that requires you to submit to a NICS background check is the stripped lower. The rest are just metal parts as far as the government is concerned. Now, you may live in a state that requires registration. You will need to check with your local laws but if so that too should be keyed off of the stripped lower.
What is the FFL part that it needs?
De'De K on Dec 3, 2018
BEST ANSWER: The only go part id the lower receiver. The kit your looking at I have 3 of them and their the best I've ever owned. No ffl required with the upper rifle kit it fomes straight to your door. Psa is very good with customer service and fast shipping...they dont pay me for my response I'm just throwing my opinion out there. I love psa
Is the M16 BCG on this kit full auto?
Dwayne W on Nov 16, 2018
BEST ANSWER: Yes However it will not fire full auto in your rifle, it is just made to the M-16 specs
Is this one or any of these builds capable of shooting 223?
Danny lee on Nov 4, 2018
BEST ANSWER: All will fire 556 and 223.
Just so I’m clear, if I want to replace the handguard, I would have to get a new gas block and do away with the front sight?
Matt V on Nov 30, 2018
BEST ANSWER: Only if the hand guard you are replacing it with is longer than 9". There are plenty of drop in options that let you keep the front sight/gas block.
Is there a left handed option?
Chad M on Jun 27, 2018
Can the front site br removed and a different hand guard be installed?
Blake on May 21, 2018
BEST ANSWER: Yes, but if you don't want this kit's front sight or handguards, you should look for a different kit.
Is this just 5.56 or multi calibers?
Donnie H on May 19, 2018
BEST ANSWER: The rifle kit is 5.56 / .223. "Multi Calibers" marked lower can be used for the build.
Very interested in buying and building my first AR, will this kit have all parts for a complete build if not what's needed to complete the build. What tools are required for assembly?
Larry B on Nov 25, 2018
BEST ANSWER: This kit has everything you need to build you AR except for a stripped lower receiver. As far as tools, watch the Larry Potterfield "How to build an AR-15 lower receiver" video. Video will provide instructions and tools needed. Hope that helps.
Just got this kit what basic rear sight would you recommend? This is my first ar
Joe W on Sep 11, 2018
BEST ANSWER: If no optics are to be used then I would use an A2 type, with or without the carry handle. If you plan on using some kind of scope, then one of the many flip up types.
Short cycles and seems to be ammo specific. Is there a fix for that?
Matthew H on Jul 17, 2018
BEST ANSWER: Ck the alignment of the gas tube and gas block. If the holes are not aligned insufficent gas may be getting thru.
I don’t have an AR and would like to get one, and are there any specific parts on this kit that aren’t mil spec that I should be worried about?

Glad tohave my first mid-length
The kit was excellent. All parts present and when the lower was built, it yielded very precise groups right out of the box. I love the recoil reduction too (even though a carbine length is nothing to complain about). This rifle runs great. Thank you PSA!

Can’t go wrong with this kit from PSA!
This kit is well worth the money. This is the kit that got me into building on the AR platform. Everything is quality and well put together. My only complaints are that the tapered pins fastening the A2 gas block were extremely difficult to get out; I had to pound with a sledge for a long time to remove them, and I believe the barrel is torqued to way over 80 ft-lbs, making it nearly impossible to remove without a heavy duty vice. I would recommend this kit to anyone looking to get into building AR’s as it is affordable, well made, and looks great.
With free float rail and some other additions
With moe handguard.
