I tell guys to keep their original parts when assessorizing their
new guns. Makes no difference if AR or a lever action. The best
way to sell most guns is in original form. The "custom" built stuff
is worse and always has been. A guy has a bolt action rifle made
up to his specs. Fancy stock, aftermarket trigger, premium
barrel, ect- ect. This doesn't include labor of Smith. You would be
lucky to recover cost of the barrel chambered and installed. If the
rifle is chambered for your pet wildcat it's worth even less. Now
with Guns made of plastics and stampings coming of assembly
lines like fish sticks, very few of them will be worth anything in
the future unless it is do to a political situation. There were a lot
of ARs bought for over $2K in last scare.
