Dropped bcg on concrete

[retrorichard]

On my cmmg mk3 (308 ar), my bcg slid from my upper onto my garage floor.

It hit on the rear of the bcg ( the outside edge that touches the buffer). I can feel a tiny bit of roughness now.

Should I polish the back of the bolt carrier, and if so what grit sandpaper should I used?

Polish it out with 220 and work up until it is smooth. Then see if it runs.

Thought this was gonna be a joke. BCG used to be short for Birth Control Glasses....

Pretty sure these rifles have been through hell and back in actual war zones...

Pretty sure you will be OK with a little sandpaper.

If you happen to be near the Owings Mills area at some point soon I can throw it in my lathe and touch up any deformed edges and do a quick polish of the area.

If you take off too much your buffer Detent will contact the buffer when going into battery. Don't take off much.

Also check your gas key for damage.
