Is this pistol just 5.56 or will it take .223 too?
Josh.s on Sep 29, 2018
BEST ANSWER: Dont buy a gun.
What is the weight of this kit when assembled?
Davie I on Nov 2, 2018
BEST ANSWER: I just finished this build last night. Total weight without the sights was heavier than I thought coming in at 5 pounds 11 oz. I will tell you that it feels lighter with all the weight between your hands.
How hard is it to remove the flash can if desired ?
Steven P on Sep 14, 2018
BEST ANSWER: Lefty lossy and righty tighty.
Is this legal in PA?
Can I file SBR paperwork on a later date to convert this?
Patrick L on Sep 6, 2018
BEST ANSWER: Yes, its absolutely legal in Pennsylvania, and you can later after paper work and tax stamp finalized, then sbr it. Pennsylvania is still a free state! I have one with the shockwave brace.
Overall Length Assembled?
Jorge F on Oct 27, 2018
BEST ANSWER: From a review.... "Total length brace retracted 27 3/4" brace extended 30 1/2"."
Can you buy this just as the upper and with FN CHF barrel?
Lance on Nov 13, 2018
Is the barrel in this kit HPT and MPI?
Quang V on Dec 19, 2018
BEST ANSWER: Usually if its not stated, then its not.
What's the interior diameter of the handguard, would like to put a can on possibly?
Dustin L on Nov 10, 2018
BEST ANSWER: My caliper shows 1.33 in.,inside, but keep in mind that the handguard is not round, it has 7 sides and a larger cut out at the top for the gas block. The 1.33 in is between the flat sides. The outside diameter of the flash can on it is 1.19 in. I hope this is of some help.
Is the barrel marked as "Freedom" or "Premium"?
Caleb P on Dec 16, 2018
BEST ANSWER: Does not say CHF. Therefore it is marked Freedom.
If I have a stripped lower receiver that is marked Rifle on it does using this kit make it an SBR instead of a pistol ?
J D on Mar 25, 2019
BEST ANSWER: I believe if the lower receiver was originally assembled into a rifle you cannot put a offer on it with a total barrel length of under 16 in would be illegal it would need to be registered as a short-barreled rifle .Enter
On a kit like this one. Would a lower receiver be the only thing I need to get for it?
Capone_50 on Mar 20, 2019
Will a Omega 300 fit inside this rail?
Danny on Sep 10, 2018
BEST ANSWER: will not
I have a gem tech g5 quick detach suppressor will it fit in rail?
Hugo V on Dec 12, 2018
BEST ANSWER: Any muzzle device with a maximum 1.25" diameter will fit inside the fore end. measure carefully.
Are the sight included in this kit?
Tyler on Mar 29, 2019
BEST ANSWER: There were with this one. They're just cheaper plastic version, but I often see same deal without the bk up flip ups. If it say MBus in the description then they will be in there.
What lower do I get to match with this?
Knightrock on Feb 22, 2019
BEST ANSWER: For mine, i got an aero precision ar15 stripped lower gen 2 and everything fit up nicely for me.
What is the recoil like on this?
Mike S on Feb 20, 2019
BEST ANSWER: I bought a holosun and KAG to go into it when I finished it and she shoots perfect. I’m 5’7’’ and when I go from the low ready to target it’s the perfect length. Literally point and shoot type of length. No added weight in the front and the brace holds great especially for an adjustable one. Highly recommend this platform and company. Hope this helps!
Does the rail have m-lok at the 12 o'clock position?
Scott S on Jan 30, 2019
BEST ANSWER: Yes it does
Is this rail-style fore rail considered as making the barrel "free floated"? Is there "flex" of the fore arm toward the muzzle, preventing steady bipod use? Thank you.
Donald S on Dec 5, 2018
BEST ANSWER: Yes this is free floated handguard because it's mounted at the receiver and not just clamped on to the barrel. Since the barrel is fairly short (on this particular setup) I wouldn't think barrel whip would be a huge issue but you'd be mounting the bipod on the mlok sections of the handguard anyway.
Does it come with magpul backup sights?
Jaredd C on Mar 27, 2019
BEST ANSWER: The acronym MBUS stands for just that. MagPul BackUp Sight. So yes, this kit comes with them.
Does this upper have an adjustable gas block?
Victoe A on Mar 5, 2019
BEST ANSWER: Mine has a standard low profile gas block. Non-adjustable.
What is the distance from center of trigger to end of brace when fully extended?
MrMatt on Jan 14, 2019
BEST ANSWER: Center of trigger guard to back of brace fully extended is 13" and fully retracted is 10-1/4" with carbine length buffer tube. This set up shoots really nicely off of the right side of the chest.
is the bolt MPI and HPT? IF so is it stamped on the bolt?
Kim R on Dec 13, 2018
BEST ANSWER: It should say Tool Craft if it is a Tool Craft. Sounds like you were sent a generic BCG like I was. Pay attention people, you will probably not get your Tool Craft BCG. You will pay but wont get.
What all will I need to make it fully operational and also may I put a red dot & foregrip on it?
Junior W on Apr 18, 2019
BEST ANSWER: Build it on a unbuilt or pistol lower. The dot will attach to the rail and so will a vertical grip.
Legal in CA?
MajesticMoose on Feb 17, 2019
Does this have any QD Sling attachments already milled in or do I need to by some MLOCK adapters?
krisos s on Dec 31, 2018
BEST ANSWER: There is a total of 3 QD sling mounts on each side. There is one on the pistol brace as well as the on the handguard. On the handguard there is one about 2.5 inches from the upper receiver and another one about half an inch from the end.
Is the handguard an in-house design or made by a different company?
Dustin W on Nov 14, 2018
BEST ANSWER: It has PSA logo's on it. I like the rail, it is slim and fits my hand well( I have arthritis and it works for my hands).
M-lok + 1913 @12 o:clock, m*lok@3,6, & 9 o'clock positions.
Not familiar with pistol set up. I have a PSA AR-15 Lower Safe/Fire - 1728 stripped lower. Is this ok to use on this set up, legally speaking?
MJB99 on Apr 23, 2019
BEST ANSWER: Yes. It will be a considered a pistol.
My kit arrived today. I bought a stripped lower a few weeks ago. The only thing I don't have is instructions. How do I get them? What else do I need for the build?
Brad B on Mar 25, 2019
BEST ANSWER: There are a ton of good youtube videos on how to assemble or disassemble the AR platform. If this is your first time set aside about two hours and find a room with a solid color hardwood floor in case the springs get loose on you.
Would a flash hider extend beyond the end of the handguard? Are there any that would work?
RobTheDog on Mar 24, 2019
BEST ANSWER: No. It would have to be a longer than normal flash hider. An A2 flash hider for example would've be about 1 inch shorter than the end of hand guard.

nice gun build!
The upper is good quality. I received to safeties in the kit and no spring and detent for the stock. Took about 9 days to get the correct part. Did not think upper was ever going to ship after I placed the order. Over a week to ship and receive the replacement part..
