The ultimak was 80 i think, the tdi foreend was 50, and I got the tdi grips (fwd and rear) for 30 each. All from blackjackbuffers ........ The biggest improvements here are A. the scout rail. I have an aimpoint for that with an ultra low mount for cowitness. and B. The rear grip. Not only is it G27-ish, but the angle is actually different. It's much more FAL than AR or AK. I also picked up one of his safety levers that has a notch for the bolt and a finger tab for one-handed operation.
The adaptor for the AR stocks is like 20 bucks I think and the stock is new at 180
Altogether, the rifle was 800 (pre-ban and unfired as far as I can tell since '89) it's a 56S. And the add-ons wereabout 400 bucks. BUT the work was a little tiring. Lots of grinding with my drill and some interesting sanding bits. Plus, blackjackbuffers are not the friendliest mercahnts out there, in my personal experience. I won't be dealing with them again. They were not late on shipments or anything, just really really 'curt' for lack of a better word. Like if I asked them to confirm that a certain part fit, they replied "it should" and when further prodded, they got downright snippy. many times.
BUT lowammo is top notch and brightflashlights is now a tdi dealer, so all is well.
I also have a streamlight TL3 in a TDI mount for the AK.... Requires a shim and takes three 123's, but it puts out a few more lumens than a G2 or 6P.
