Got a local engraver who is willing to engrave an AR for me for an SBR configuration..... Any suggestions on what to tell/suggest to the guy as he tries to engrave the lower? Wasn't sure if there were some commonly acceptable settings for AR's |

A laser won't be able to go .003 deep, but they won't try and do it with a laser so you're OK. Don't bother going any deeper than .003, there's no reason to. By my understanding there is not a height requirement for SBR markings, only the depth. Who's going to engrave it, if I may ask? Thanks.. |
I had a trophy shop close to my house do it -- This is not a alum lower, this is a polymer lower by Cav Arms -- lot easier to engrave. They do NOT have the proper tools to engrave a metal lower. |
Wrong, the spec is "1/16" high 0.003" deep in a conspicious area" meaning it can't be covered by a grip or stock. There are lazers that can engrave that deep, but they are not as common as other less powerful units. |
The lasers I have seen work by repeatedly passing over the same area, so if it will cut, you just keep passing over and over the same area until it is as deep as you want. Mine took 6 passes. |
They are probably being carefull or are very weak The hotter the engraving, the more prone it is to melting which will look like shit. The engraver I went to used a 25 watt laser at less then 20% of it's potential power. There is also an engraver in town with a 75 watt laser that is capable of cutting into stainless steel. |
The engraver Ken is talking about is powerful enough to cook a reciever, he dials down the power and makes several passes to keep the heat down. He also does engraving on commercial grade machine parts. I would not hesitate to recomend him but I don't think he is licensed to recieve firearms through the mail. He happens to be local and we just walked them in and were present while he did the work |
