The SLR-104FR has recently been introduced to the US market and I snagged one off the first shipment. Here's what I've found…
-100% reliable to date with mostly 7N6 and some Red Army Standard thrown in (69gr) occasionally
-Build quality is great. Everything's lined up, locks in tight, and the sights are nice and straight
-CHF CL barrel made on the famous Arsenal Bulgaria Steyr machinery
-Finish is vastly improved over other Arsenal rifles I've seen in years past.
-Accuracy (with an optic) has been right around 2'' groups (some slightly over, some slightly under) with 7N6
-The only one I can really think of would be cost. But, considering the price of other '74 variants on the market I really don't think $1100 is bad. I'd bet they could charge $1300 or more and still move them if they wanted to….
Here's my review video with some shooting, a discussion of the features of the rifle, and my overall thoughts on it:
