Hello forum guru's,

So, Ill try not to write a novel in my first posting. Long story short, I have a rather strong attraction to the G3/HK91 weapon system, but a shoestring budget, thus PTR has found a special place in my gun vault. I bought a 16" PTR32 Gen2 as my first offering from the company, and absolutely loved it.

But, I'm the manager of a gun shop, and I'm the only guy without a cool SBR, and I'm feeling very left out. I looked into the ballistics of a .308 PDW, and decided against it, So decided that I'd get a full size PTR91 to build a G3A5 clone (Norwegian military issue battle rifle) complete with spikes tactical 37mm flare launcher.

And then for my SBR I decided to sell my carbine PTR32, and go with a PTR 32 Pistol, form 1 it, and put an A3 stock on it. The idea of an MP5 style sbr that fires 7.62x39 cartridge seems pretty freaking awesome to me.

So in my thread searching it seems the two options to me are.....

Go 12", and use a standard A3 stock (currently available) and not cause myself a huge headache.

Go 8" and try to find a PDW A3 stock (currently NOT available) and likely deal with lots of frustration. My question here is, the PDW A3 stock has the collapsible recoil rod. but is otherwise the same it seems. Is it possible to use the recoil rod and spring from the pistol end cap, and transfer them to a standard A3 stock, to make a PDW A3 stock? or is there more to it than that?

Thank so much for any thoughts and opinions on the subject.

Well you passed on the G3K size because of ballistics, so given that the sensible choice seems to be the 12" 7.62X39.

Unless fireballs are what you're looking for in the SBR, but in that case wouldn't PTR's 8" .308 be more flashy than the 7.62X39?

I'm less concerned with the ballistics of the x39 round, and they respond to shorter barrels much better than the .308 does. So really the primary focus is the smallest i can get the PTR32, with a reasonable amount of effort. I'm building a long range rifle for hunting and target shooting in 6.5x55 swede, so the PTR32 PDW would be a "home defense"/giggle factor gun, that would likely get used exclusively at indoor ranges from 20-50 yards, maybe out to 100 yards (yay living in northern Virginia with over population and no open spaces).

My primary concern would be the feasability of putting the available A3 stocks on the 8in barrel PDW length firearm. I'm pretty handy, having been a mechanic, custom wheelchair fabricator, and current armorer at work. Just not well versed enough on the firearms to know if I can do the conversion without completely building something from scratch (ie breaking it and having no pew).

Sounds like you've already made up your mind. All you'll have to do is install your recoil rod from your 8" pistol into the A3 stock.

DO IT! Honestly, I love the PTR32 8". Cheap Wolf ammo, surplus AK mags work great all day... Sounds good suppressed. VERY happy with mine.

MT162 - if its really that easy to swap the rods, then I'd say I have a winner. Thank you much for the confirmation.

gopherboy128 - oh that thing is sweet. How's it run? still respectably accurate out to 100 yards despite the pistol length barrel?

Yes. On the 8" model, you don't swap the rods, you just remove the back plate and install a stock section, once your SBR paperwork is approved. All I had to do was buy this https://www.hkparts.net/shop/pc/viewPrd.asp?idproduct=1144&idcategory=114 and bolt it on

Quick question....where are you finding either of these in stock? I can't seem to find the 8" or 12" version anywhere.....only the 16" carbine version.

Do you plan to buy a 7.62 can for this rifle? If not, firing an 8" barrel 7.62X39 indoors in a "home defense" situation will be very problematic. The flash will be so bright in low light, you won't see anything for several minutes. Also I found an 11 1/2" barrel in an enclosed space to be too loud for single hearing protection. So if you fire the 8" short barrel in your home in low light, you might as well set off a flash bang grenade 8" from your face. As far as I know, all the major can manufacturers require at least a 10" barrel to stabilize the bullet. So as far as "home defense" an 8" 7.62X39, sounds like a very poor choice to me. An 8" barrel is too short for can use for noise and flash reduction. Your money, your choice. To me 8" would be fun for outdoor, middle of the day, "shock and awe" kind of rifle. If you actually want to use a short barrel 7.62X39 for "home defense", I would highly recommend a 12" barrel with a can. EBR makes 220 subsonic ammo that will cycle the action. So subsonic ammo in a 12" barrel with a can, would be a better choice IMHO. YMMV.

I seen where Atlantic has posted were PTR will be making 7.62X39 guns soon. Not my gun but http://www.gunbroker.com/item/622293486 could be a good start to a 12" gun. There are a couple of smiths that can cut and thread a barrel in the receiver. So file the Form 1. Once approved, cut the barrel with a hacksaw. As the "maker" you need to be the one to shorten the barrel below 16". You can take it to the local trophy shop to have your info engraved will the gun is still Title I. Send the SBR yo one of those smiths, they shorten, and thread your barrel and refinish the gun.

I want to start off by saying that I'm not taking into account your budgetary restrictions. Ballistically speaking, from what I've seen on something like an 8" barrel you're better off going with 300 Blackout than you are with 7.62x39. The 7.63x39 has an edge in muzzle energy but the bullets in the 300 Blackout rounds have a better ballistic coefficient and do better down range. Also it's a much nicer round to suppress and you have versatility with easily available commercial supersonic and subsonic loads. Now, to actually get one your options are limited. Brethren makes one and Dakota Tactical will be making one. Parabellum is working with RTG to make a HK33 flat and when that's available he'll be another option. Other builders might be doing them as well. And there's always doing a barrel swap on a HK53.

This is just my opinion and we all know what those are worth but personally I would never want a rifle caliber firearm with a barrel any shorter than about 12". Although I must admit that I don't want to have to go the SBR route at all. I just don't like the hoops you have to jump through and the extra restrictions. If I did however 12 to 12.5" is the length of barrel I would want. I think it makes for a better balanced rifle that is very handy without hurting ballistics to bad or throwing fireballs.

I am currently in the process of trading for a Gen II PTR32K pistol with the 12.5" barrel. I plan to have an extended flashider pinned and welded to it to bring the barrel up over 16" so I can attach a stock. Perhaps someday I will actually file a form 1 had SBR the rifle but for now I think this will be close enough for me.

+1 what scottinthegrove stated. I own a PTR32K with a 12" bbl. it runs like a top in semi or full auto. Very good accuracy out to 100 yards (I haven't test farther). I added a Manitore brake that RTG sells. A real crowd pleaser at the indoor range! I went with the clubfoot stock & thick buffer. Very easy on the shoulder.

Have you verified that personally? I have 50 rounds of their stuff, and it doesn't cycle my 8" PTR32, with or without a can, and trying several different locking pieces.
I've used the EBR subsonic in another platform. It worked in both an 11.5" and 16" AR uppers suppressed and unsurpressed, that would also run Yugo brass cased surplus. I don't own a 7.62X39 roller locked. Just have not gotten around to it. I thought if it would cycle an AR it would cycle a roller locked, but I have not tried it in a roller locked.

I have a Dead Air Wolverine pending. I will use the EBR Jackhammer stuff in it. My 8" PTR32 sounded good with Wolf and a Saker 762 suppressor. Cycled fine too.

So Atlantic is saying possibly 6 weeks for both of the pistol models to be in stock....I think it may be worth the wait. Very much leaning towards the 12 in version and pinning a 4" flash hider while I wait out the sbr process with the atf.

Heat Fire Flame Gas you want to shoot this in your home?? The thought of hearing the percussion bounce off the walls along already make my ears bleed. I have had a hard time getting mine to run. When it does it's fun. Firearm Gun Trigger Rifle Assault rifle

I'd go the 12 inches. Get a PAP M92 of you want the 10..25 Get a Bulgarian Arsenal rifle that you can cut the barrel if you want a 7.62x39 in 8.5.

I heard the first gen of PTR-32's had bad mag figment on some popular mags. If it doesn't run good, you why don't you send it in? They have this super duper warranty. They had my rifle fixed and sent back refinished and all in 1 week
