What is the difference between chrome moly steel and chrome moly vanadium?
Joel C on May 7, 2019
BEST ANSWER: 4140 chrome molybdenum alloy steel, with the addition of vanadium alloying, which refines and improves the crystalline structure of the alloy. In other-words, a finer grain structure that increases tensile and yield strength, and mechanically the finer grain pattern provides higher burst strength and resistance to stress failure from repeated impact, along with increased hardenability and temper/stress relief heat treating.
Vanadium addition in a tool steel or high carbon alloy is an excellent alloying improvement agent all around in every alloy it is used in.
Does this kit have to be shipped to an FFL since it has a stripped lower?
Kelsey H on May 4, 2019
BEST ANSWER: It does not need to be shipped to an FFL. It includes every piece to assemble the rifle besides a stripped lower (the only item that ever requires an FFL). I suggest buying one of those locally to avoid fees.
Is this a complete M4 rifle when completing the lower?
Rich.Fore on Apr 27, 2018
BEST ANSWER: Yes it is. It’s a very nice rifle. Brownells has a very nice detailed article on how to assemble it. You might want to order an extra set of detents and springs. They can get away very quickly. The first one I assembled took a day. I had to make three trips to get extra detents and springs. The second one I assembled took two hours. Enjoy.
Never built one before, is it difficult for a first-timer?

Can a low profile gas block work on this kit,and if so do u have to change fore gaurd ?
Chris P on May 8, 2019
BEST ANSWER: You can install a low-profile block and keep the existing furniture. There is no real good reason to do so. Seeing the front sight in your optic really is not a problem.
If I want to replace handguard with picatinny mloc type, what other parts would be needed? Can I use existing gas block?
Dima Prok on May 9, 2019
BEST ANSWER: That is a question with varied answers.
Yes you could use the existing has block if youbused a rail sized for it or used a rail with fsb cut out.
That being said is a more difficult approach as the fsb will need removal for most options like the ones mentioned. The process to remove the fsb can be an involved one. My suggestion is to watch some videos on fsb removal and also about re-profiling the fsb to fit various hand guards. As to other parts needed to switch hand guards most will require a new barrel nut often included with the rail being purchased. You will need a vice some sort of reciever block and a torque wrench..often a barrel nut tool of some kind is provided with quality handguard purchases meant tobfit that specific hand guard. All of this should be undertaken after watching some informational videos about barrel replacement and rail replacement.
Hiw difficult is this to assemble?
Julius M on Nov 17, 2019
BEST ANSWER: It’s as difficult as spelling “how” correctly .
Do these kits come with assembly instructions?
Harold B on Oct 1, 2019
BEST ANSWER: It does not. However, there are tons of instructional videos and guides online. I just put this kit together today using a video from YouTube. My first build ever and it took me less than an hour, and the only tools I had were a hammer, screw driver, and socket set
What stripped lower would you suggest for this kit?
Cliff T on Jul 27, 2019

Let's say a guy had an Anderson stripped lower for an AR will that work with this M4 kit?
William on Oct 27, 2019
BEST ANSWER: YES. Absolutely. Your stripped (“poverty pony”) lower + this kit + about an hour = a complete AR style Modern Sporting Rifle (MSR)

PS: no offense about the Anderson lowers - I have several and just ordered a few more on sale!
Does this kit include everything to create a functional rifle?
GoBeav494 on Jul 30, 2019
BEST ANSWER: My kit included everything but the lower receiver, and a rear sight. The only other things you need are a good set of assembly tools and a little time. I couldn't find a spot on the 'blemished' product. Excellent value and final results exceeded my expectations. The rifle shoots really well. I've had zero malfunctions or issues post assembly. PSA has crazy fast shipping as well. I couldn't give a higher rating for this package.

Saif Alhameedi on Jun 26, 2019
BEST ANSWER: It is fully semi-automatic.

Does it come in left hand model?
BLEM PSA 16" M4 CARBINE LENGTH 5.56 NATO 1:7 NITRIDE FREEDOM RIFLE KIT - 507617B
JD P on Nov 14, 2019
BEST ANSWER: You could get a Stag Arms left handed upper assembly and transfer all of your parts to that, but no this doesn't get offered in a left handed model.
BCA has left handed products you might want to look at.
How long does it take to build and how hard is it to assemble? Also does it come with instructions? Thanks
Chris H on Oct 16, 2019
BEST ANSWER: It does not. However, there are tons of instructional videos and guides online. I just put this kit together today using a video from YouTube. My first build ever and it took me less than an hour, and the only tools I had were a hammer, screw driver, and socket set

Does the lower have S#?
Rick C on Jan 27, 2020
BEST ANSWER: REALLY? There is no lower with this kit just the parts needed to make YOUR stripped lower function. If you bought that lower stripped. It t probably has a serial #. Exception would be If you bought an 80 % or a raw forging
Just double tapping, the lower receiver is not included but will any stripped lower work?
Christopher G on Dec 18, 2019

Does this kit come with a trigger guard?
Robert W on Dec 7, 2019
BEST ANSWER: It comes with the standard USGI trigger guard. It is in the picture the little flat piece of metal just below the BCG and to the left of the buffer group.
Will I still be able to use .223 as well as 5.56?
Dan P on Mar 5, 2020
BEST ANSWER: Absolutely, it’s chambered for 5.56 which means you’ll be able to fire .223 in it. You just need to be cautious if you are going the other way ( 5.56 in a .223, 5.56 has higher pressure ) I have fires plenty of .223 in mine ! Works great !!!
