Thanks very much, gentlemen! I started with a new 5.45x39 Saiga and did the proper chop/cut/grind routine, adding an Arsenal adjustable trigger (awesome, by the way). The rail on top is an aluminum setup, which gives space for the Magpul back-up sights. The optic is an Aimpoint Comp M (older model), and I shaved off the front sight base to clean up the lines. Funny thing was, I even *gained* some sight radius, not to mention the much-improved sight picture of a ring-and-post aperture. The grip is a Magpul MOE, bolted to a grip stud converter that I got from Carolina Shooters Supply. The rail is a UTG model, and the rail covers are a mix of Magpul and UTG. The Tapco 6-position stock tube and a Magpul stock bring it nicely into the shoulder.
The ACS stock I added (not pictured) gives it more balance, and beefs up the rear-end to match the rest of the rifle. The AFG (also not pictured) lets me run the gun in my preferred thumb-over-bore method. Next step is to take it to my machinist and have him thread it 1/2x28. I foresee a suppressor in its near future, though since it took me 6 months to get my first one, it'll likely be just the kinda-near future, haha
