Agree with the BC Steel Lips assessment...I've used the Hot Lips on my 10/22 with different brands of ammo and there is always the occasional jam. The Steel Lips have not jammed once...unfortunately, I was told by my local gun shop that as of the middle of last year or so, Canadian customs have not allowed any more new shipments of BC 10/22 mags across the border for some reason...what exists on shelves will continue to sell, but no more new mags are coming in...not sure if this is true or not, but if you do find the Steel Lips mags, it would be a good pick-up, for sure. BTW, if anyone does know for certain any store in the Toronto area that still has existing Steel Lips stock, please PM me. Thanks!
