I am curious if installation of the brake will detract from the resale value or collectability of this rifle in the future.
BEST case scenario is that you'll get what the rifle was worth before modification. You'll never get back the cost of the brake. Much more likely though is that you'll take a financial hit if and when you sell it later on.
Collectability? Definitely diminished. It will be valued at a "shooter" basis, rather than anything collectable.
