I don't think this will work, come to think of it, on a 15-22 cause it's not a rail bipod but a sling stud bipod- A week ago today, last Friday I found a $40 Winchester 9"-13" bipod at Walmart- exactly like a Harris but not $100 and I put it on my Remington 597 (a scoped rifle 597, "sporter" version) and it's the truth- really nice. Maybe it's not a Harris, the only thing I seen about Harris about how they're nicer is they "Mount better and tighter" , maybe thats true. All I have to do is hand - tighten a little screw, if and when it loosens up. Just hand twist the thing, to snug it better, and it was $40 not $100.
So I love Harris as much as the next guy, but this Walmart $40 bipod made a huge difference on my 597. Again in retrospect I don't think it would work on the 1522, cause only rail-mounted ones would work right?
(And let me ask you this: it's not an Optic, it's not a big deal, What's the harm in an NcStar or UTG bipod rather than Harris? $20 bucks is a lot less than $100.....I'm not SAYIN, I'm just sayin...)
