I want a 7.62x39 non ak rifle for HD and range fun.
Careful there, Jay the Plinker, you said "7.62x39" "For" and "HD" in the same statement. Anyway, why not an AK? Two good economic solutions to your question are the Saiga and the Chezh Vz.58. The latter only resembles the AK externally. Other options are the SKS, although your seeming distaste for Russian weapons probably rules that our. There is also the Mini30, which is pretty much a Mini14 that eats 7.62x39 ammunition. For 7.62x39, there really is no better choice than an AK.
I have done my research and Sig's 516 Russian (piston ar-15) and the 2012 sig 556r (heard they fixed the problems are on my list. I can't find the 516 r anywhere online. Has it just not come out yet.
The Sig516 Russian came out in 2010. However, I've never heard of it until I read your post about say, 351 seconds ago. I'm not certain about importation, availability, quality, or price. IMO, one of the biggest advantages of the 7.62x39 round is that it's typically slung from a Kalashnikov rifle; you're doing yourself a disservice by trying to cross-class two very different design paradigms. I understand that some folks just flat out don't like the AK at all. However, Sig Sauer has infamously high prices and a lack of support in the United States. I'm uncertain as to whether or not generic 7.62x39 AR mags would work with the gun. The 7.62 Sig gun is notorious for having issues with firing and feeding, and problems with steel-cased ammunition. Most of your just for fun 7.62x39 ammo is going to be cheap bulk steel case.
I also like the ptr32, anyone have experience which these. What are the trigger pulls like and where can I find them. I could go for an ak (I guess) but you'll have to post picks of mounted optics because I do not like the ak's sight. I do like diopter sights in the ptr and for the sig 556.
The PTR-32 got good marks from The Box 'O' Truth, although it is definitely heavy and quite expensive. Say, have you got a budget or put any thought into the logistics of supporting such a gun? Getting mags to work with it seems to be hit and miss. As far as reliability, accuracy, and such goes, it's a modified G3; you aren't going to have any problems. It's probably the best non-ComBloc solution I see to your question. Now you say that you dislike AK sights. You can replace the rear notch with an aperture sight, and there are rails for adding optics. In my opinion, open sights are the quickest and easiest type of irons to use in CQB, which is what home defense is.
