Building an AR15 pistol

[ntomsw]

Someone walk me through it. I've built 'full-size' Ar15's, and now I want a pistol.

I am curious to see what length gas tube you get for what size barrel, etc.

I want a 7.5"-10" barrel, and the length of gas tube has me confused.

Do they also use carbine buffers & springs??

Any help let me know. Thanks.

this looks like a nice AR pistol barrel
7.5 inch barrel
I hear they have fantastic customer service and product support, I'm sure they will be glad to answer your questions about your build

If someone could also post a Ma. compliant version of an AR pistol with pics. & parts list, I'm very interested myself.

Did you really just recommend Neil a Ice Arms product? I'll let him tell you his experience.

somewhat interested in this as well, starting with one of those plastic lowers can the weight be kept under 50 oz? what other non-ban features are needed?

This is the barrel I went with.

It is a pistol gas system. On a 10.x" 5.56 barrel or longer you would be using a carbine length gas system. If 300blk is what you want, I think you can run a pistol length on any size barrel.

A pistol buffer tube uses carbine guts unless you are using one of those funky short ones, I don't know much about them.

I am very much looking forward to banging away with mine.

 

[ntomsw]

So on a 10"+ barrel, it's a carbine gas tube? So I am guessing anything shorter than 10", it is a pistol length gas tube??

And yeah, I won't be buy anything from Ice Arms. Ever.

Also, what about ammo? Can you shoot standard 55-62grain ammo out of a barrel that short?

How about one of thease?http://www.model1sales.com/index.cfm?fuseaction=category.display&category_id=338

 

[ntomsw]

I already have a dedicated AR in .22lr

Not polymer.

I shot a bunch of green tip out of a friend's 7" gun.

Mine has a 8.5" barrel and a 7.5" rail with pistol length gas tube. Also a Phase 5 pistol buffer tube with a carbine buffer and spring.

Wow. Very nice. Do you happen to know the weight, without the mag & sights?

 

[ntomsw]

Rock River Arms has a nice 7" barrel assembly, but it's a 1:9 twist.

All my other AR's are a 1:7.

Would that 1:9 be able to shoot 55-62 grain ammo ok?

http://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_id=272



I might just go with the one Ed posted at Core15.

http://core15rifles.com/core15-7-4150-cmv-1-7-barrel.html

Only $150.

I wouldn't worry about the 1:9 twist until you start getting up to 69+ grain bullets. The Core barrel was cheap, and that is all I wanted, a toy to shoot cheap russian steel ammo at plinking ranges with. I will likely be looking for either a 11.5" BCM or a DD MK18 upper after the new year so I am ready to SBR when I get the tax stamp in.

Mines from Bison Armory but it's 6.8spc

I weighed it today at work with the Optic it was 5.5 pounds. The optic does not weigh that much anyway.

Thanks. I was trying to get an idea of how much I would need to chop off in order to make the weight restriction in Ma. I'm going the sbr route.
Otherwise it's gonna end up looking like this:

That is gnarly.

 

[ntomsw]

I am very tempted to get that 10.5" upper. Good for a pistol now, and for if I ever feel like doing an SBR.

Very tempted.

I wish it came with a BCG and CH.

If it was a complete, I would have already bought it.

want to touch the hiney.

my LMT in the same condition ran me $550-ish.

10.5" barrel, 29.5" OAL (sez intarnet) when it's a SBR. when i have the lower i am building a pistol with the upper.

 

[ntomsw]

I want to buy something, but I am trying to hold out for Black Friday, to see what kind of deals they have.

It's killing me though, because this would be perfect for what I was looking at.

Sig has a P556 AR pistol for sale with a funky buttstock:

Likely not MA compliant but interesting. And ATF approved as handgun in normal states.

 

[ntomsw]

That thing made by Sig is the ugliest thing I have ever seen.
