Thanks in part to this forum I am now the proud owner of a Saiga 7.62x39 conversion. I am an old guy and for physical reasons like the idea of an Arsenal polymer solid butt folder. I'm aware of the ACE and such but not interested. What I am learning the Arsenal and its folding mechanism might not be an easy installation for me to do to my Saiga and if not, probably too expensive to have it professionally done. I saw a knock off but it appeared to have a long block extending back from the receiver, something like the TAPCO folders, don't care for that look for the money involved. Anyone have experience with the Arsenal? THANK YOU all for your posts, helped me a lot in doing my conversion.
