Yes, but not as easy as it sounds. We are looking into adding our own on the existing rail in the clearance slot, but this still needs to be affordable. If the European market pics this up than it will be standard. If I Was to sell you the existing one it would cost over 1000 dollars. Of course the repeats are cheaper but development still takes time (The one in the pics), I agree in the benefit of BUIS but if you can remove the whole system in 25 seconds and the original is still there I somewhat question the need. Nonethess it is coming, it is alot more work than even I thought. You cant just fit a product to one gun, because of manufacturing tolerance. You have to make it to one gun and then fit it to everyone you can get your hands on just to try and establish tolerance. I am thinking about doing a free online seminar(hopefully on Gunnutz) about using measuring tools (mic,vernier,indicator) just to get some extra help and a bit of educating.
