Jody, if you can do a M-lok hybrid rail at 12 inches with seven side attachments, slimline and lightweight (not bothered about the front picatinny on the sides like on the SLR, the solo version does not have them) That fits the 15-22 without a gap....
Well then my friend you have a customer right here! Shut up and take my money.

Please, please, please make this happen My biggest fear with forking out $250 on the SLR is that it wont fit without a gap, i could get a cheap China M-lok hybrid that would do that for $50.

I eagerly await what you are producing
