What lower can I buy ?
Dio702 on Jan 2, 2019
BEST ANSWER: Any mil-spec A2 lower will work. I'd recommend an Anderson, PSA or Aero Precison A2 Lower.
does this kit come with a barrel?
nite f on Jan 4, 2019
BEST ANSWER: Did you even read the description before posting this question?
Can this be sold to a New York resident?
David M on Jan 6, 2019
What else will I need to complete the rifle?
Johnny K on Dec 19, 2018
BEST ANSWER: Stripped lower, rear sight and a mag
What is the difference between the ar15 and ar16 upper receiver?
Jerry H on Jan 2, 2019
BEST ANSWER: The AR-16 was a 7.63x51 prototype. It was very different to the AR-15 and if you somehow have an AR-16 lower receiver, this will not work.
Can the front site be removed ?
Israel J on Dec 18, 2018
BEST ANSWER: Yes, but it requires a quality punch set and many really good hits with a hammer. Pins are tapered so will only punch out one way. I have attempted this on two different PSA FSBs, once with success and the other time I had to get the Dremel. Some may be in there really good so just be away of what you are getting into.
Whats the difference between the "Freedom" rifle and the "Classic" rifle kit?
Chris on Jan 20, 2019
BEST ANSWER: Comparing the specs on the two pages, it looks as if the color of the furniture and the steel used in the bolt are the only differences
Do you have to go through an FFL ?
Robert on Dec 28, 2018
Is the upper assembled ?
Steve G on Dec 26, 2018
BEST ANSWER: Yes. Place it on your completed lower, insert the pin, and you're ready to shoot.
What tools will I need to complete this build? From a first time kit buyer (obviously)
Jason S on Jan 20, 2019
BEST ANSWER: Bare minimum tools need to assemble a AR lower, (since the upper is already assembled).
Hammer preferably brass or other soft metal, Pin punches 1/16 and 1/8 inch, Channel locks type pliers
(internet search for pliers trick for bolt catch and trigger guard installation should find you videos), electrical or masking tape to cover jaw of pliers.
Armorers or castle nut wrench for installing the buffer tube assembly, (in a pinch a brass punch can be used)
Another trick for installing the front take down pin spring and detent is to use a 1/4 inch clevis pin (another internet search should find you a video)
Which PSA rear sight is required for this build?
Pierce on Dec 29, 2018
BEST ANSWER: No sight is "required", PSA or other brand to make the rifle functional.
Target acquisition is another subject.
What caliber rounds will this rifle shoot besides .223 and 556?
Will it take the 300 Blackout
Donald L on Jan 17, 2019
BEST ANSWER: Rule of thumb: A rifle in 5.56 can shoot 223 but a rifle in 223 cannot shoot 5.56. Neither can shoot 300 blackout. You need a 300 blackout upper to shoot the round.
Are the parts packaged in groups like "Trigger assembly" ect?
BigJohn on Dec 29, 2018
BEST ANSWER: My PSA kits have come grouped in that way. If they didn't, a quick Google will show you which part is which.
What magazine does this rifle take?
Manor L on Dec 26, 2018
BEST ANSWER: Standard 5,56/ 223 magazines, I especially like Palmetto State Armory aluminum mags always a great value!
Will this shoot .223 ammo?
Tman0520 on Dec 26, 2018
BEST ANSWER: Yes, all day long!
Is the buffer kit made from 7075 aluminum or 6061 aluminum ?
mjasper on Feb 3, 2019
BEST ANSWER: Yes, one or the other.
Does this kit come in grey?
Jimmy C on Jan 22, 2019
BEST ANSWER: Did you search the website ?
Is an FFL require for this item as it is component parts?
Edward N on Feb 11, 2019
BEST ANSWER: No. This will ship right to your door because there is no lower receiver.
Is this freedom rifle black?
Jack B on Jan 27, 2019
H buffer or carbine buffer? Milspec buffer tube or commercial?
Jason on Jan 5, 2019
BEST ANSWER: Carbine buffer and a milspec tube
What does it take to convert 223 cal to a 22 cal?
J E on Jan 1, 2019
BEST ANSWER: You need a conversion kit like the CMMG - AR-15/M16 22LR BRAVO CONVERSION KITS. Simply replace the rifle’s bolt and carrier with the Bravo .22 LR conversion unit, load up the included magazine with round-nose .22 LR ammo, and you're ready to shoot.
Can a different forearm be installed?
Larry on Jan 1, 2019
BEST ANSWER: Yes. However, some forearms may require a different barrel nut. Most free float hand guards will come with the required barrel nut.,

Shaun W on Feb 28, 2019
BEST ANSWER: yes any stripped lower for ar-15
Will this kit work with a fixed trigger guard stripped lower? Such as Spikes Crusader?
Norbert B on Jan 28, 2019
BEST ANSWER: Yes, if the Spikes is machined to industry standard/milspec.
Can I add a "classic" handle to the top of this?
Jack B on Jan 27, 2019
BEST ANSWER: Can you ? Depends on if you have one or not.
Do you guys ship to Illinois?
Kyle Y on Jan 26, 2019
BEST ANSWER: If you have a FOID to upload, and specify a valid FFL in IL, yes they do.
Can I add a classic carry handle on these?
Jack B on Jan 26, 2019
BEST ANSWER: Yes, any mil spec carry handle rear/sight assembly will fit on the upper receiver of the kit. These carry handles will clamp onto the rail machined into the upper receiver. These carry handle assemblies are available from PSA.
Will you shop to California?
Christian Q on Jan 20, 2019
Will a 1.7 twist barrel be ok for all weight bullets or should I go with a 1.8 or a 1.9 with a 223 cal?
J E on Jan 1, 2019
BEST ANSWER: A 1/7 barrel will stabilize 55-80 grain bullets. 1/9 will stabilize 35-75 grain so a 1/8 is kinda right there in the middle so I’d choose it. However all twist rates will be fine with the most common 55 and 62 grain rounds.
does the kit require an ffl ?
joseph d on Mar 4, 2019
BEST ANSWER: No ... This kit can be shipped right to your house. The lower is the only part. that has to be shipped to a FLL.

Great kit
Purchased this kit last year about this time, everything looked great, the parts fit my Aero receiver without any issue and the rifle has not had a single malfunction. Accuracy is just the same as my factory S&W, Bushmaster and DSA, I will recommend this to anyone who is looking to get a good rifle on a budget. My example performed way above its price range. I have only put about 500 rounds through this rifle but like I said, so far no malfunctions at all, and accuracy is on par with my other three.
March 17, 2019
Stock is somewhat loose or flimsy but other than that great kit.
Definitely would recommend buying this kit and I would also buy another.

Poole's New Standard Grade Carbine Withe PSA upper
After years of producing match grade rifles we decided to build a standard grade that would perform well at the range. The PSA upper was our first choice to complete this project and it proved to be the correct choice.
PSA upper with a Poole's Match Lower. This is our standard grade AR platform carbine.
