i put it on my colt and it worked great. plan on buying a couple of more and build one for each one of my kids so i can keep mine
- Good value.
So far I have no complaints with this upper. It does have a polymer receiver, but since the bolt action cycles within itself, I don't see it being a problem. The included mags feed well, just as well as my Black Dog magazines in my opinion. I run CCI AR .22lr ammunition with minimal issues, as well as Winchester bulk pack. Both seem to work equally well. 3 or 4 failure to feeds combined with both brands(about 250rds total), but I suspect a proper break-in and keeping it oiled will remedy those problems.
The bolt does put lateral force on the buffer pin, I may end up cutting a wooden dowel to place behind the buffer the prevent wear. Don't know if it's necessary or not, or just me being anal about it.
