Ever gone to fit the rail to your rifle and you just can't get it lined up properly, or the barrel nut hits the receiver before the barrel itself is tight?

Prometheus knows your pain, so they've made these super-handy little packs of rail-mount shim rings that should sort out the problem and get your M4/CQB-R or other AR-15 back together straight, true and without the dreaded barrel wobble!
