Is the Sparc red dot included? It is shown in the picture but not mentioned in the description.
Rick D on May 13, 2019
BEST ANSWER: Yes, it is included.
what model sparc is it?
JakeB on May 21, 2019
BEST ANSWER: If it is as shown in the pic then it is the SPARC AR.
If I live in Colorado, which disallows magazines over 15 rounds, can I purchase this? Would I just send them a note and ask them to not ship the mags then send it to an FFL?
Frank on Jun 3, 2019
BEST ANSWER: Go to Centennial Gun Club. They have "magazine parts kits". I used to fly to Sydney or Cheyenne to get mags.

Hey PSA, would you please offer said parts kits? It's legit here in CO. With the floorplate separated and the spring hanging out it no longer fits the legal definition of a magazine. It would be illegal for us to assemble it... Which we obviously would never do... A few places have been doing it here since 2013, no issues.
What magazines ship if my state has 15 round max capacity law?
Spartan on Jul 4, 2019
BEST ANSWER: Move to a free state.
I have been advised that in FL the lower must be stamped with the phrase “multi use” as opposed to 5.56. The theory being that 5.56 is a rifle round thus making this a rifle. How is the lower unit stamped?
James S on Jun 13, 2019
BEST ANSWER: does not come with a lower.
Overall length? Please and thank you

What is the inside diameter of the rail? Trying to see if a can will fit.
Dave Y on Jun 24, 2019
I'm interested in turning making an AR rifle. This is by far best combo deal on the site. Can I turn this into a rifle by buying a 16" barrel and substituting it for the 10.5" one? Would I have to change any other parts?
Steve on Jun 23, 2019
BEST ANSWER: You would need to change the buffer tube and brace. Aswell as the barrel.
can this also shoot .223?
Cesar N on Jun 20, 2019
BEST ANSWER: In short, yes. Try google for the long version.
Will this build accept a silencer?
Dennis G on Jul 11, 2019
BEST ANSWER: Which 'silencer' do you have?
What is the barrel profile before the gas block?
Michael D on May 26, 2019
BEST ANSWER: Barrel Profile: A2
Will this ship to California?
Xerox on May 21, 2019
BEST ANSWER: Sounds like everything but the mags unless you are law enforcement (according to what they feel law enforcement are) and have signed doc's from your department head

Aside from the lower receiver, is there anything else not included? I can't tell if for example, if the trigger guard is included.
Reaver960 on Jul 9, 2019

Yes, the lower receiver is the only thing you will need.

I lived in Colorado. Can the 30rd mag be replaced with 15rd magpul mags?

Great Value, Reliable, Ok Accuracy
In the last week I’ve put 400rds down range with this build. It has run flawless except for 1 FTF, which IMO was magazine related. I’ve run 7 different loads without a hiccup — 55g in .223 (Federal) and 5.56 (Federal and Winchester) brass case, 55g steel case Tula, 62g green tip XM855, 69g Razor Core from IMI Systems, and 77g SSA by Nosler. It has all run great in the 10.5, including mags loaded randomly with all of those. Accuracy has not been great, (3-4 moa at 50yrds with the sparc on a bench rest) but I’ll reserve full judgement until I can test with better optic. I know this is early in the life cycle but i’m impressed so far.
The value of this package is really REALLY good! The NiB BCG, SBA3, Vortex Sparc, and 10 gen2 Pmags are conservatively a $350-$400 value alone. If you’re looking for a fun range “pistol” in 5.55 I don’t think there is a better value to be had out there. Overall, I’m very pleased with this kit for the price and I’ll be a return customer for sure. Well done PSA.
Paired with an Aero lower and Hogue grip I had sitting around

Great buy, fast shipping overall satisfied!!!!
Loved this buy, couldn’t have asked for a better AR for my first build. Palmetto state has some of the best prices and there products are great!!!!
More than I expected and a great price all I did was add the lower with a new charging handle!

Awesome deal!!
I wasn't really sure I could put this together but after I searched around and found some good instructions it was fairly easy. I put it on an Anderson stripped lower which has a color mismatch but it functions. Mags,sights and red dot were extras and to be honest the thing looks badass! They even sent an extra spring and pin knowing I'd lose one but found it later. lol. Awesome job PSA!! Took 6 days to get. I would definitely recommend. Shoot em if you got em.....FREEDOM!!!
Awesome freedom toy!!

A Christmas Story
This is my first purchase with Palmetto. I’m currently overseas but each night I dream like Ralphie from A Christmas Story about building this into a beautiful pistol. Going to use the deplorables lower. Can’t wait to upload pictures once it is all put together.

Great deal, Great pistol.
Great pistol. I will buy more from PSA. Went together with no issues. Shots great. Shots as well as pistols that cost twice as much and they didn't come with all the extras. Highly recommend.

Great Deal!
This is my first AR-15 build. Paired well with the PSA stripped lower. I put it together in about 1.5 hours. I sent one detention pin and spring across the room, but I found it. Lol This is a great deal. Upgraded ni B bolt carrier. 10 mags, sparc red dot sight. Pop up sights and I bought some ammo for less than a base model off the shelf at a sporting good store.
