I am not an engraver, so am not sure what "SBR" engraving is.
I did get some Glock slides engraved by a guy in San Antonio that uses a laser and does excellent work...VERY reasonable prices too.
What are you wanting to get engraved on your AR?
The BATF requires all registered "SBR" Short Barreled Rifles be engraved on the lower receiver with the owner/builders name, city and state. It also has to be visible without the lower receiver being taken apart. I don't believe a laser engraver will do, because it has to be a certain depth. I believe the depth has to be .003 and the laser engraver does not go that deep. Please correct me I'm wrong about the laser engraver depth, because I would really like to do this in town and not have to ship the lower out to anyone.
certain laser engravers can do it first pass, the more powerful ones. the weaker ones have to make multiple pass' as i understand.The BATF requires all registered "SBR" Short Barreled Rifles be engraved on the lower receiver with the owner/builders name, city and state.
