I’ve been on a roller lock kick the last year since I received my form 1 for my MP5 clone.
I am now wanting a 7.62x39 roller lock and PTR offers the 32p with 8.5” barrel and the 32k with 11” barrel. I want to get the form 1 paperwork going but have a few questions.

I would prefer the shorter barrel but it looks like the stock options are limited. I only see one stock that might work with that setup. I’ve read the buffer springs are different between the two guns but still don’t understand what stocks will fit which gun.

What options do I have with each firearm?
Will any G3 stock fit the 32k?
Is this the only option for the 32p? (Will it even fit?)

I just don’t want to buy the firearm, take the time to mail in the form 1, then wait 10 months to get the paperwork back to then discover nothing will fit on the ptr 32p.
