Custom H&K 51 A cut-down and short compact version of the G3, the 51 is a U.S gunsmith creation, not an H&K factory option. This one has had its furniture dipped in multi-cam, which doesn’t look too bad. I like that its only the furniture and not the whole rifle. As a buyer and seller, refinishing your entire firearm in one color or camo-style usually hurts your chance to resell it. Even if you paid a gunsmith to paint your gun in skulls for $350…your potential buyers are already figuring out how much it’ll cost to remove your paint job.
