As i mentioned in Building help (1) this is a first time for me, and I truly thank everyone for the replies.
I've got the Building the AR-15 Riffle CD by Bob Dunlap, and Build your own AR-15 by Duncan Long. I've started on tools and so far have the Critical Tool Kit f/Brownell, and their Punch Set, and a Barrel nut wrench that came with MI M lock Gen 3 15" hand guard. I had it put on my MP 15. I see I've got a few more to get (by the video) My question is what is the difference between a enhanced upper and a upper? What should I do, buy a Mfg. Kit, or the parts? Personally I'm thinking parts (like a receiver parts kit,upper parts kit etc.). When I get the few more tools I'm thinking of taking one of my guns down and putting it back together (the S&W, I'm not fooling around with my Rock River) for the experiance. What do you guys think?:nailbiting:

I said I wouldn't recommend it. Not sure what your point is. I still wouldn't recommend it. They can be made to work reliably, but the blast is still excessive. The round is less effective too, but honestly I don't worry that much about that since the chances of me actually shooting someone are slim. But you'll find my opinion is a pretty common one. I also have a 9" 300BLK, and while the round is more effective from a short barrel, I frankly find it too short. I have to grip it all the way at the end to be comfortable. And I'm probably not going to put a light on it, but if I were I feel like there's no room.

As far as your SBR, I hope you don't actually have a stock on that rifle. And I hope you built it from a stripped lower and assembled it into a pistol before ever putting a 16" upper on there. Because otherwise you're committing a felony and I'd delete those posts if I were you.

I had asked a few post ago about buffer springs being an issue with the shorties. That's because I keep seeing . I thought they were all the same, and today I found there is (to me) no difference. Am I correct in that assumtion?:headscratch:

Oh Jack I was only kidding with you..honestly! I listen to everything you guys tell me because I know you guys will guide me correctly. As far as the SBR it's not finished yet, I put the upper on one of my lowers to get a feel of what it will be like so I adjusted the sights. Why not, there going to stay on it.
You have me mixed up talking about a stock, putting a 16" upper on there, a stripped lower, built it. It's not built yet i'm still waiting on parts, stripped lower of course I've got 4 of them. I'm going to apply for a stamp I'm not that stupid :supergrin:.

Eric can you do me a favor and delete my post on SBR please. I found the form on the BOATF web site and put it on adobie to fill out and send of. I would really appreciate that more than you know THANKS

I'm referring to the fact that once a rifle always a rifle. From your prior posts I believe you have 4 or so stripped lowers. So when you got them from your FFL dealer he should have listed them as "other" on your paperwork. If I were you, I would build each of them into a pistol first. That means a barrel less than 16" and no stock. If you build a lower into a pistol first, you can change back and forth from pistol to rifle. If you build it into a rifle first, then you can never make it into a pistol. If you do it's a felony. Once a rifle always a rifle. And a pistol is absolutely different than an SBR. By no means should you ever have a stock and a barrel less than 16" on a lower at the same time. If you do that prior to getting your stamp, you're creating an illegal SBR. The NFA doesn't make a lot of sense, but those are the rules.

I've down loaded the form to fill out tomorrow and get it off. I see what you're saying now, but I'm going to get that stamp first anyway!!! I've got to much to lose for doing something stupid

Also just to clarify, the phrase "once a rifle, always a rifle" is a bit misleading. It should be more like "started as a rifle, always a rifle" or "born a rifle, always a rifle".

"Once a rifle, always a rifle" makes it seem like if you took a pistol and put a 16+" barrel and butt stock on it then it has to stay that way, which is false.

ALL...AR bolts carriers have the same exterior diameters. ALL of them. An AR 10 BCG is the same diameter as a AR15... The reason this is true is they all use a common diameter receiver extension. There is no difference between a AR10 "buffer tube" and an AR15. So the fact that a bolt carrier group wouldn't fit in an AR is problematic.

Now the bolt head itself is a different deal and also the length of the BCG's differ.

If you can't insert a BCG into the back end of the AR something is REALLY wrong...OR you don't have the bolt pulled fully forward in the BCG so the cam pin is aligned with the charging handle/receiver. But AR15 and AR10 BCG's are the same diameter.

I apreciat what your saying however upon calling the dealer about the situation the rep. Pulled one off the shelf came back to me letting me know I was right and to return the product and he will take care of me. It's the O.D. of the carrier.

That's fine.

That stamp will be good for only the one lower it's registered to. You will also need to have the lower engraved with your name (or trust name) and city/state of residence.

You will be able to swap uppers, both long and short barreled, onto that SBR stamped lower without any other issues.

If you decide to travel and take that stamped lower across state lines you need to notify the ATF by submitting a form beforehand.

Thank you as well as all of the guys for the educational information you've given me on the subject. I'm not thinking about those 3 words for a while. I'm still getting the stamp just to have it for future use I'm not in a rush. I think I'll do the pistol. I just want to do another build different. Also from individual parts to build from scratch. I don't have to use the stamped lower right away do I ?

The lowers I bought didn't come from the same place, I caught the holiday sale and from my FFL store just to have as that Mfg flies off the shelves fast

Question: When looking for a pistol buffer and associated parts what do you guys suggest without breaking the bank.
You all told me what enhanced upper was but I see quite a bit of other things enhanced (FCG, BCG,) is that to charge more? Next thing will be enhanced water :supergrin:
