Can you change out the front site sight and can you change out the hand rail on this build?
Tom Tom on Dec 21, 2018
BEST ANSWER: Yes the FSB can be changed out, there is no hand RAIL on this kit, there is a hand guard though and it can be changed as well.
Is this Kit CA compliant?
Jacob on Dec 31, 2018
BEST ANSWER: In short No. The standard lower parts kit does not conform completely. You will need this kit which is legal to own plus additional hardware to choose either the fixed mag approach or the featureless approach as of (01/01/2109) for your rifle.
So, exactly what all would need to be purchased to make this a 100% complete, ready to put some lead down range, weapon? And plz be real specific.
Duane A on Dec 19, 2018
BEST ANSWER: All you'd need to make this kit into a complete and functioning rifle is a stripped lower receiver and potentially a rear sight as I don't see one pictured or mentioned anywhere
Is this a complete ar15? Thanks
Gumaga on Dec 28, 2018
BEST ANSWER: No, it’s just the upper assembly and lower parts kit. Still need a stripped lower (must ship to a FFL) and magazine.
Can you shoot .223 and 5.56 with this kit?
Robert L on Jan 3, 2019
BEST ANSWER: Yes. You can shoot .223 in a 5.56 barrel just fine. What you should not do is fire 5.56 in a .223 barrel. Why all of my small caliber AR have 5.56 barrels.
When your build kits are complete they are fully functioning rifles?
Zues9911 on Dec 23, 2018
BEST ANSWER: You will need a stripped lower as well. A rear sight or scope and a magazine.
Does this item ship to California?
Metram M on Jan 3, 2019
BEST ANSWER: It’s shipping to my address in Cali. So yeah
The description says this includes a BCG but unless my old eyes are deceiving me the photo doesn't seem to show one?
Sam H on Jan 1, 2019
BEST ANSWER: The BCG is installed in upper. Dust cover is closed. Blow up pic and you can see charging handle.
Has anyone had an issue with the barrel being loose and a lot of play between the upper and lower? If I hold the upper and the flash hider and turn the barrel. The barrel moves. This is my 1st psa gun and it seems to be very loose compared to my bushmaster.

PSA 16" 5.56 NATO M4 Carbine Classic Rifle Kit, Flat Dark Earth - 5165450369
PSA "SC" Lower
BEST ANSWER: Yikes, I used an Anderson lower and mine are all tight. I have a bunch with no issues.
Is the A2 flash hider removable or will a separate threaded barrel be needed to add other muzzle devices?
Taten S on Jan 5, 2019
BEST ANSWER: Yes, the barrel is threaded 1/2x28 tpi and the A2 FH is removable.
Does this rifle require an ffl !yesthis is a question?
Tone2all on Jan 17, 2019
BEST ANSWER: No this kit does not, the lower receiver requires a ffl because that is the “gun” with serial numbers.
Can I attach a flashlight or laser to included hand guard?
Drake S on Jan 16, 2019
BEST ANSWER: No. But you can buy a different forend on a budget online.
It it exactly as pictured?
Nateslovnlife on Jan 14, 2019
BEST ANSWER: Exactly as pictured ...
Does this have trigger gaurd?
Rayscot59 on Jan 13, 2019
BEST ANSWER: Yes, Mill spec...
Is a FFL required for your ar 15 rifle kits?
lenny on Jan 10, 2019
BEST ANSWER: No only lowers.
Can you build this for left hand/am I set up?
Joshua P on Jan 9, 2019
BEST ANSWER: what is the question ???

The case deflector on the upper makes LH shooting workable without hot brass going into your face. With training... standard RH controls can be manipulated with efficiency.
Does upper come assembled?
Rigo G on Jan 7, 2019
Are instructions on how to assemble included? If not where would I find them? Manual or on DVD?
Jaime M on Jan 6, 2019
BEST ANSWER: 1 - No. 2 - youtube has a number of videos on how to assemble a lower.
Is this the Freedom line of qualiter... or better???
Grab a on Jan 6, 2019
BEST ANSWER: From what I can tell this kit would be a lesser quality than the pre assembled freedom rifle kit. The real difference is in the BCG, this kit has a 9310 Bolt and the pre assembled Freedom Rifles have the mil spec carpenter BCG. There is a similar kit to this one for 299.99 that is closer to the prebuilt freedom rifles. However I own this kit and don’t think the bolt matters as much for casual use. If you intend to use it heavily I’d pay for the better bolt.
Does this require shipping to an ffl?
Ken J on Jan 6, 2019
BEST ANSWER: No. The stripped lower receiver is the part you have to have an FFL for
Can this kit be shipped with upper unassembled? It would be a project/cerakote gun.
Jamie H on Jan 4, 2019
BEST ANSWER: Negative.
I am looking at a 6.7in "carbine length"quadr ail for it, will this fit?
Sonny on Mar 18, 2019
Can I ship this kit directly to my home or does it need to be shipped to someone with an FFL?
Curtis on Jan 20, 2019
Will this work with a aero precision lower that has a 60 degree saftey?
Jared P on Jan 18, 2019
what kind of steel is the bolt carrier?
reyes 0 on Jan 13, 2019
What stripped lower receiver would I need to get?
Ryan G on Jan 11, 2019
Does any have any recommendations for mounting a rail on the bottom of the handguard (if I keep it)? I'd like to add a foregrip
ShadoWolf512 on Jan 9, 2019
Does the upper have T-marks?
Guy R on Jan 7, 2019
I would like to build one. Could I switch to a longer barrel in the future, if I wanted?
Steve M on Jan 6, 2019
BEST ANSWER: Yes barrels can be replaced. Longer barrel would require a longer gas tube and a new handguard as well as a bit of research and correct tools. It is more common to replace a barrel than an entire gun so it’s not that difficult, watch youtube videos for the process. The Ar-15 platform is relatively easy to do anything yourself.

Great starter rifle
I bought this thinking it would make a good beater or truck gun, I put iron sites on it ,then a Sig red dot. For a cheap rifle you can't beat the quality. This gun is a great shooter. If your building on a budget this is the gun for you.

Great start for a budget build.
How can you go wrong? Add a 39.99 lower and a Romeo5 and have a great weapon for around 440.00, 340.00 if all you want are iron sites. Wait for a Daily deal and save even more.

Great kit at a great price right to my door!!
Kit came to my door as promised and well packed in perfect condition. Had already ordered and received a lower a year ago. All components went together perfectly and in a very short time. Could not be more happy with my purchase and the price was right as well. Look forward to shooting the gun at my local range.
Before assembly.
Less than ten minutes later!

We'll worth the sales price.
Not a real tight fit up to my Anderson lower, but pretty decent. Trigger is smooth, but typical mil spec. Bolt/ carrier gp works smooth also. Well worth the sale price which left me room to do some add ons.
Installed on my Anderson lower. Added mag well extension, m-lok handguard, flip up rear sight.

great price great gun
Only shot a few boxes through it but runs perfectly fine so far. The only complaint is the stock rattles a little when moving but otherwise well worth the money.
