Hi,

I'm hoping to have the railed gas block on my M&P-15OR replaced with an A2-style FSB locally. Any recommendations for a gunsmith/armorer in NoVA who can install and taper pin the FSB?

PM inbound; interested in buying your old gas block.

I wonder what kind of drill bit tapers... Must be a specialty drill... Sounds like delicate work too. Not too deep, not too shallow, but right in the middle, and end up in the middle on the other side too.

Maybe a new barrel would be easier and cheaper, sell your old one?

Let us know how it goes...

No, standard drill bits (#30 IIRC), but a tapered reamer is used after the holes are drilled.
