so I'm going to build an AR..... well this would be the second one ..... but the first was many years ago now.

I'd like to go with a 7.62x39 upper due to how far my $$ can go in the ammo dept.
I'd also like a piston upper if possible.

being a full on AR noob essentially, what are your recommendations for building up an upper in 7.62 x 39? optimum barrel length? twist rate?... any "packaged" uppers in this cal that you would recommend? ..I'm not concerned with match acuracy, let's call it a zombie gun for cqb and inside 150 yards. I have optics as well so no need to go there. furniture i can look after .... it's my inexperience with the latest greatest in canadian accessable internals that brings me to the black rifle experts here for some advice.

so.... what are yer thoughts?
I'm diving back into black rifles purely for personal enjoyment and would like to build up a simply wicked x39 :D
 
If you are only going to use it within 150 yards the PWS Diablo has all your criteria. Barrel length is quite short, 7 inches I believe, but it's piston driven.

MHO - Get a VZ-58 if you want to run surplus 7.62x39 that is in most cases corrosive.

If you are just after a funky AR build the 300 Whisper is pretty cool and will run a regular bolt and mags.

:agree:
& if you were running MFS or better non-corrosive I would go with Clobbersauras said.

I seem to be one of the few with absolutely zero desire to own Vz-58 or one of those 858's .... just not my thing.... would take a beat up mismatched sks over one of them any day..... call me wierd and no offense to those who love em.
I want the Ar to be in x39 due to the availlability and affordability of the ammo..... plain and simple...... and if i wanted to shoot .22 cal i'd shoot my 10-22 , 223 doesn't do it for me. 6.8 would be a awesome choice but again availlability of ammo and cost of said ammo factor in and x39 still becomes the best choice for my particular needs with this rifle
300 whisper is a very attractive idea ...... but where am i going to get 5000 rounds for a couple hundred bucks a 1000???? not happening
 
Are you actually going to "build" an AR, or are you going to buy an upper and a lower and slap them together?

Huge difference.

I bet you could reload 300 Whisper for less than the cost of surplus 7.62x39. Form the cases from cut down 223 and use surplus pulled military 150gr bullets. Powder charges are typically 9-10gr per round. Doesn't get much less expensive than that.

The biggest problem with 7.62x39 AR's is that the bolt was not designed for a case head that size. In order to accept the larger case head the bolt has to be opened up with weakens it and results in bolt failures, which can potentially cause a lot more damage if things go badly.
 
Not to hijack the thread but Hornady is now selling 300 Whisper ammo it two weights; sonic and subsonic.
 
Doc,

Although everyone seems to just love "Piston" driven AR's, I do not. They are fine if the Queen or the President are buying your parts for you and you need a rifle to stay cool and basically clean but the AR platform as designed by Mr. Stoner (Who did not like piston guns by the way) is not really designed to handed the force of a short stroke piston. The gas impigement system is a much more gentle system and trying to drive a rifle designed for this gentle push with a hard shove is not the best in my opinion.

I have used and built AR's (For competition) for over 25 years now and the addition of the 6 or 7 parts required to do this does not make sense to me.

I have a couple of rifles in my cabinet that have had over 25,000 rounds through them, I'm waiting for one to fail but that has not happened so far. My match rifle gets cleaned once each year after fireing every weekend and some week days for 8 months straight, I only do the barrel and wipe down the operating parts. Carbon is a lubricant you know!

ok, now that I have time to type a proper answer...

1) Piston vs. DI. I think that the US Army is heading down the piston route as their trials have indicated that a piston system is worth looking at to improve reliability during long periods where the soldier might not be able to clean or maintain his FULL AUTO M4.

I would not, however, buy a piston AR just yet. There are literally dozens of piston makers out there, all with proprietary systems and non-interchangeable parts. When the US Army selects their piston system next year, most of these companies may disappear or their offerings change to match the GI spec system that everyone will want. You'll be stuck with an unserviceable paperweight if your system turns out to not be compatible.

If I was buying now (and I just bought another AR), I would go DI. Next year (ish) when the GI system is selected, you can upgrade since the piston system request for proposal means it has to be retro-fittable on the existing Colt M4 inventory.

2) If you want to build, you can select every part you want to install. The end price is comparable to a pre-built AR, but ideally you choose your parts to best fit you. Either route will work.

3) I would not go 7.62x39. I would go 9mm or 5.56mm. Reason being legal 10 rounds mags. No 10 rounders exist for 7.62x39. 9mm is cheap ammo - if cost is a concern, I would go that route.

Cheers.
 
this is pretty cool info. appreciate all your comments.
I suppose the first one will be an "assembly" rather than a 'build" in that I'll want a complete , proven upper in a CQB format (in my case that means as short as possible).
I won't be steered away from the 7.62 x39 config for this rifle however, it's ammo i already have stock piled, it's non corrosive and will last me for years :D I also do not own any x39 rifles. I've been there done that 100 times over with the sks family in the late 80's and early 90's so those and the 58's and the 858's and the whole AK thing has lost it's magic hehehe

so shoot me some ideas for a reliable but wallet wise assembled upper and where in canda, other than in the ee should i be shopping :D
I'm gonna get a phone call from Satain any time now asking me if I got hit on the head or somethin .... LOL , he's always wondered why there's no AR's in my safe :D
 
ok, well if you want a complete upper in 7.62x39, and want to buy it new, there are really very few choices. It's possible to build one, assuming Questar has the key bits in stock, but for complete uppers you have PWS from Questar, TNW from Marstar and MAYBE and option in the Stag lineup from Armseast. Dlask might also offer something.
 
There are two things I'd never run in an AR:

1) A piston (well, maybe the H&K...)
2) 7.62 x 39

I can't fault a guy for pissing money down the drain as I've done alot of that myself. Have fun with your build and let us know how it goes.:wave:

If you need parts I have two brand new LMT bolts that fit the x39 case dimensions (.473?)
