Diy Ar

[K31]

I saw an ad for a stripped upper receiver. It did not say that it need to be sent to an FFL but I assume that this is the only part that does.

If I transfered this would the FFL do the paperwork for a regulated weapon and that would be the last transfer I'd have to do to build an AR? In other words could all the other parts be sent directly?

Does it take a machining to build an AR? Would it require anything other than hand tools? Any books specifically on this?

Could I use this receiver as the basis of a 6.5 AR?

 

[jpk1md]

I was looking at building one from scratch.

I decided to buy my first one as a complete gun and will be purchasing a few lowers to get them into the safe. This gives me a reference point and the opportunity to get to know the gun a little better first

The lower/reciever is the only part that requires an FFL.

Purchasing an Upper (complete or otherwise) is just like purchasing any other non-class 3 parts like barrels, bolts, firing pins etc.....plunk down the cash/credit and walk or have it shipped to your home.

You can purchase stripped receivers for ~$170 or you can get complete ones for ~$450

The rest I don't know about.

Assembly of an AR normally does not require any machine work. A few specialized tools will make the job easier. A standard upper receiver will work for the 6.5.

You will need a few different sized roll pin punches. Then a few different sized brass punches. If you are going to buy the upper in parts, you will need an amrorer's tool. It's almost impossible to pu the barrel on the upper receiver without having a barrel clamp which means you will need a bench vise.

The lower is the registered part, everything else is mail order.

We sell the stripped lowers for $155 for DPMS and RRA, the POF Billett lowers are $240

Building an AR is a pretty stright foward operation. There are a few special tools that you need, mainly a barrel nut wrench, bolt dis-assembly tool, head space guage and carbine stock wrench.

Some things can be avoided like the stock wrench if you are planing on using a A2 stock, and the barrel nut wrench, bolt dis assembly tool and head space guage are not needed if you buy a pre assembled upper.

I buy a lot of stuff from Adco Fire Arms and Rainier Arms. They both have quality parts and ship quickly. I usually have my parts w/in 3 bussinness days.

When you say "we sell" I assume you mean Continental?

Is there any way to build one in such a way that it is an HBAR and not in need of registration?

I assume that like pistols the same "No bathroom stops allowed" rules apply for other regulated firearms.

Thanks for the info.

Only way is to buy it complete with the heavy barrel.


Strange, eh?

Kit Builds...

Take a look over at AR15.com in the Equipment Exchange. You will find dealers selling stripped lowers for $100 shipped to your FFL. All other parts can be sent to your home. I put a Stag together this way a few months ago. Total build was under $650 including transfer fee, shipping, etc. It shoots like a dream and I am happy. Also AR15.com has a nice feedback area and they monitor the transactions history. You can feel safe dealing with these people.

Good luck,

+1 for AR15.com, they have all kinds of info, how to's, and a lot of pics of other folk's builds to give you ideas. (they also have an AK section).

I put together a 20" A2 last month for under $700 (only because I paid Fulton $170 for the lower before I knew about the $100 ones online.. live and learn). I just picked up 5 Superior Arms stripped lowers for $550 with the transfer fees, now just need to save up for the kits.

I am planning on buiding a M$ in 6.8 spc this way. already have a lower by DSA picked out. Can't wait to get started on the project.

Two more AR's came into the world this week.

I had the two lowers assembeled, one is a Bushmaster the other is a Superior Arms.

I then ordered 2 CMMG uppers, both 1:7 twist, 14.5" barrels w/ perm attached Phantom flash suppressors. One is a A2 the other is A3 with a detachable carry handle. I have to Dura Coat the handguards on the A3 gun to match the Dura Coated stock and grip. I have 7 mags already done is OD green for that gun. It's also getting a LMT rear sight, La Rue Aim Point Mount and Aim Point Comp M3 sometime this summer.

Then I decided to get a couple more lowers. So a POF-415 came home along with a Rock River LAR-15

My family of AR's. I have 4 more to build, so many options, so little money!

 

[DD214]

That is a beautiful family you have there, and congratulations on the two newborns! Have you named them yet?

I don't even want to ask how many mags you have to feed all those "kids"

just a quick technical question. I have been told that heavier bullets need a faster twist rate to maintain stability. someone suggested that if I build an AR in 6.8 spc I should I go with a 1:8 barrel. I am a little confused because most of the premade 6.8 uppers that I see advertised in shotgun news have a twist rate of 1:10.

 

[Norton]

Dangone brother, you have quite a brood there!

Y'all don't have any lowers at the shop do you?

6.8 doesn't follow any traditional standards, the AR in 5.56 needs a 1:7-1:9 to stablize most of the modern bullets. Most are chambering in 1:9 with the exception of CMMG and most Colts (some Colts are still chambered in 1:9, the A3 Tactical IIRC)

All the 6.8" I've handled have been a 1:10 twist. You have to remember they only needed to fit the round into an AR lower, everything else was from the ground up. But the best I've sceen with the 6.8 in an AR (A Barrett) was 1.5 MOA using Silver State ammo. It isn't a tac driver like the 5.56 can be, it just kills better.

I'm down to one DPMS as of last night. We have been selling lowers like mad. I'll cut ya a deal if you are interested. I'll be there all day tomorrow from 09:00-19:00

How are those receivers compared to CMMG, Superior, etc?

On par with Bushmaster.

IM responded too!

Have you ever built an LRB AR Lower?

Wondering if you have any feedback
