Why not.
I just found out that dumb nuts I sold a perfectly good Japanese Arasaka to 12 years ago (jungle carbine with everything except the crest) turned it into a shortened manlicher stocked POS.
Chopped the barrel short, changed out the stock, removed the rear sights(the flip up aircraft sights) and replaced them with a peep sight, ground down the whole crest area to clean it up and then refinished it to make it look better.
I am disgusted now.
And to top it off he never ran more than the one box of 7.7 that I gave him then through it. And lost the brass to boot.
And the finish on the gun is crappy and the wood looks like a beaver carved it and a blind man finished it.
AHHHHHHHHH!!!!!!!!!!
And this last weekend when he showed it to me he actually asked how much I thought it might be worth now.
I thought he was collecting it for historic value.
As for your little addition to your gun. Go for it. Its small, reversible and if it helps you to shoot it then run with it.
