Engraving a Smith and Wesson M&P 15-22 lower

[Bluto]

I just got one of these bad boys in pistol form and am SBR'ing the lower.

https://innovativearms.com/portfolio/iasw-integral/

I brought it to my usual engraver and they told me they cannot engrave M&P15-22 lowers for 2 reasons:

1. Their laser will cut through the polymer.
2. Smith and Wesson use some kind of polymer mix that puts out toxic fumes when they use the laser.

#1 seems plausible enough. #2 is a new one for me.

The gun comes as-is and I cannot use an aluminum receiver, so please no wise-ass remarks. I don't like polymer either and this is my only polymer rifle. I know you guys are relentless with your polymer hate (lol) and it's just a range toy for my kid.

Anyone have experience engraving these? Does anyone know of a competent engraver in South Florida?

What are you talking about with "polymer hate" The M&P 15-22 is a great gun, and the polymer lower works great for that application. I'd just take it to someone who engraves plastic name plates.

People hate on polymer lowers for 5.56 guns, not the 15-22.

Why not keep the brace and keep it in pistol form. I have SBR'd guns that could have been pistols but the 15-22, I would keep that one as a pistol brace gun. Great gun and a lot fun.

Good luck.

I think Papabear presents your absolutely best option for the present.

But, as an alternative, what about finding someone who will affix a properly engraved plate permanently to the polymer? I believe that’s how the factory info is done. (Mine is buried, but that’s what I recall.)

That’s a good point, that’s definitely what S&W does. Also maybe try a different shop? Maybe some can control the output of their lasers better?

For a M&P 1522 I'd probably just do it with an electric engraver and call it good.

Thanks for the feedback everyone!

I’m not a fan of pistols. This one won’t be crossing state lines so no legal issues there and I just don’t like braces.

I’m having a metal plate engraved that will be epoxied under the trigger. Similar to what s&w does with the serial number.

Or maybe use a steel stamp set. They are inexpensive, and I can't see a reason they would not be able to work on the poly lower. I can't remember what the depth requirement for engraving is, but it's not deep at all.

My last 2 SBRs were approved with the additional engraving/marking section black and no extra engravings applied.
