Well, last week I tried atleast 5 times to get dremel my stock thingy so that it has the auto bolt release. I took off quite a bit of material, with no luck. I was ordering a hammer, so I figured what the hell and got the VQ bolt release. When I compared mine to the VQ, they looked VERY similar, i almost couldnt tell a difference other than color. So I put the VQ in and it does the exact same thing as my modified one, no auto bolt release. Is there somthing I am missing? I shouldnt have to modify the VQ one at all to get it to work should I?
