Engraving SBR Lower...

Question for the experts.

Regarding an AR, I know that the standard trigger guard can not be used as a engraving space. However, if you are using a lower that has an integrated trigger guard, it is a good spot for the NFA engraving, and many put their information there.

Is there a way to take an aluminum after market trigger guard and permanently attach it to the rifle in a manner that meets BATFE standards?? Do they even have a standard for this?

Reason, I got a number of lowers that don't have built in trigger guards. I could purchase an aftermarket trigger guard and have it engraved with the required information and permanently install it to meet regulations. One reason is I would not have to send the receiver off to be engraved and no need to involve a FFL. Plus my new found engraver can fit it into his machine.

I know that silver soldering a muzzle device is good enough to lengthen a short barrel to over 16 inches. Silver solder would probably not be a good choice for aluminum alloy. Would epoxying it work?

Tarheel State will laser engrave your info inside of the trigger guard area for the same price as anywhere else on the lower... but you don't want to send it off.

Can your guy do the bottom lip of the magazine well? Pretty tight, but you can fit 1/16" tall letters there.
