View Full Version : Assembling an SBR - DECISIONS!

I have had the itch to assemble an SBR for a while and finally bought a lower receiver the other day to start my new build. Just a couple of quick questions...

1. What length handguard should I go with if I just want the muzzle device showing out of the end with a 10.5" barrel?

2. Speaking of 10.5" barrel - Does anyone have any experience with the WOA 10.5" barrel?

3. Besides the VLTOR MUR, are there any upper receivers that do not have the forward assist? I would like to only have the shell deflector. Thanks.

We just got one of these for a pistol or sample gun.

This upper is badarse too. Fully adjustable so your able to run a can.

I think you will not find much helpful info on this forum.

We; Californians, can't easily build SBRs or AR pistols.

So not too many people will have experience with 10.5" barrels.

Last I checked, DPMS, Sun Devil, and JP all made flat-top uppers less a forward assist. Nodak Spud does as well but those are A1 style by and large.

As for the other bits...probably want to check out ARFcom.

Noveske also makes a MK18 10.5 style upper like the DD. It would be nice if LMT had a factory MK18 offering.

Also look at BCM. The variations they offer are outstanding.

Im Looking at a 10.5 or 11.5 for a pistol build. Im favoring the Noveaske at the moment.

11" handguard will give you the look you're after-

You should look thru that AR-pistol pic thread.......they're basically the same thing minus the stock. You might see something in there you like and you could PM the poster and ask them what they used.

Bragger!

Must be nice. If I were in your shoes I would build a clone of the rifle I personally was issued in the USAF. Sadly full auto is not option, or is it?

The GAU-5A/A.

A1 Slick Side Colt Upper
11.5" Colt Pencil Barrel
A1 Hider
No bayonnet Lug
CAR-15 Stock
CAR-15 handguards
Colt Lower
A1 Grip
4 Position Stock

I built an AR pistol version of it once using an Off List Pistol Lower. But without the stock it just wasn't the same thing...

Did you come to the CA forum just to piss us off? :p

Have fun with your SBR, maybe you can use it to free us Californians..... ;)

Side question: Californians can use 10.5" uppers on pistol builds, correct? (I usually see them somewhere around 7.5")

You might be surprised at just how many Californians legally own SBRs.

There are some very knowledgeble people on this site who can probably give you the answers you seek. Just give them a little while to find this thread. Also, don't worry, your post really didn't come off as "bragging". I didn't seee you sticking out your tongue or anything.

Another question regarding filling out a form 1. It seems as though it.will make more.sense.to set up a trust. Can I just use something like Quicken WillMaker to do this? If I do set up a trust, then do I leave the sections that say "individual" blank? I'm mainly referring to the CLEO section and he section that requires fingerprint cards and a picture.

Thanks! I'll provide pics in the.end as.payment. Ha.

Don't mean to derail the thread so if I am, PM me, but pretty much universally on this site people say that Californians just can't get SBRs. Is it really that impossible for the average citizen (or, say, independent action filmmaker) to get approval for one? If so, why is it any harder than in, say, Arizona?

Again, don't mean to go OT but if you have some knowledge, let me know!

Spikes makes a lot of cool options for SBRs with rails longer than the barrel, in fact the BAR rail system is made specifically to fit a can in.

I'm not surprised. I'm just saying that it just isn't the easiest thing for us to do.

And, because it's not the easiest to do less people in CA build them than people in free America.

First of all, Californian can get +50 year old SBRs just as easy as in any other state. Secondly, there are more than a couple FFLs on this site who have Ca DD permits and can get/manufacture newer SBRs. Finally, if you read my post carefully, you'll notice that I said "Calilifornian's legally own SBRs". I never said that all of them were kept or even allowed to enter this state. We have more than a few California members here who legally own SBRs which are kept in other states. I guess, I could also add all the LEOs who have sue weapons to the list but, that's not really fair, is it? Anyway, my point is that there are more SBRs owned/possessed (in the case of LEOs) by Californians than the average person realizes.

its tough because the permit you need to get one as a regular citizen (that isnt an armorer for movies) is nigh impossible to get.

So AR pistol it is for most of us, and even those are a bit of a PITA to get (or expensive).

Im really happy with mine. Ive got a rifle extension on mine (before you FUDsters speak up, its perfectly legal so save your breath) so it runs like a champ and "shoulders" fine. Not as good as an SBR, no doubt, but for my secret ops that I pull off at the firing range, it works perfect for me.

^ i disagree. a lot of californians have AR pistols.

to the OP, here's an upper with an 11.5" barrel and a (slightly longer than regular, 10-3/4") mid-length rail. so i think a 10" rail on your 10.5" barrel would be what you're looking for to have a muzzle device stick out just enough.

Reread my previous post. C&R SBRs are as easy to get into Ca ( NFA trust) as AOWs such as Serbu Shortys. That doesn't mean they are easy to get but, they are possible for the average Joe to obtain. Getting a Ca DD is alomst impossible but, Ca DOJ has issued Ca DD permits to a few people with good cause. Of course, the other way is to get a NFA trust in another state, obtain one and keep it there.

I had a few questions and did not want to start a me thread. If someone could either answer or provide a link. I searched, but not well enough apparently.

I have only assembled 16" ARs before and they have all.run reliably. What do I need to do in order to get a 10.5" to run reliably? Do yall recommend certain buffers? I will be running this rifle suppressed for a long time since it will eat up all of.my.money. Ha.

Thanks again in advance.

Maybe consider a piston upper, since shorter barrels have a tendency to lead to timing issues. Also from what I've read, pistons are going to give you less gas blowback and work better with a suppressor than a DI gun.
Here's a couple:
LWRC (http://www.lwrci.com/p-105-556-psd-upper.aspx)
Adams Arms (http://www.adamsarms.net/details.asp?sku=UA-11.5-C-TE-556) (they have a 7.5" and an 11.5")
CMMG (http://cmmginc.secure-mall.com/item/CMMG-M7-7.3-Piston-Upper-1499) (7.3")
Many of those also come already-railed, too, so you're pretty much G2G. Dunno what your budget is.
EDIT: Whoops, forgot PWS. Here's their Uppers (http://primaryweapons.com/store/pc/viewCategories.asp?idCategory11), and their complete Pistols (http://primaryweapons.com/store/pc/viewCategories.asp?idCategory=24).

You could also go with a .300 Blackout upper. Hard to find ammo, but you'll get much better performance out of the short barrel and if you're shooting subsonic ammo out if it it's about as loud as a silenced MP5. So pretty fecking quiet. Here's some complete uppers in .300 Blackout: Noveske Blackout Uppers (http://noveskerifleworks.com/cgi-bin/imcart/display2.cgi?cat=173), PWS Blackout Upper (http://primaryweapons.com/store/pc/viewPrd.asp?idproduct=276&idcategory=11). Or you could just get the upper of your choosing and buy a .300 Blackout barrel directly from AAC here (http://www.advanced-armament.com/product.aspx?pid=896#pid=896). It uses the same receiver, magazines, lowers, etc. as 5.56.

Hope this helps, be sure to show us your rifle when it's done.

Cheers,

I wanted to build this on a AR Pistol (or is this over the maximum length?) ... but hopefully it will give you some perspective. 12.5 inch barrel and DD free float rail I think the rail is a little under 12.5 inches.
