Cheesy & tacky doesn't adequately describe laser engraving on a stock.

Just because you bought a Browning M42 repo reasonably & it's not a "collectable" or rare shotgun is no reason to desecrate it.

Only Honey Boo Boo's family would consider it a "family heirloom" after it's been laser engraved.

Lot's of good suggestions here on how to do it with a little class.

If you need more room for names I like Frank's suggestion of an inletted plate. You could carry that idea a little further & put it on a plate on the underside of the stock (where the crest plate normally goes except larger).
