Q: Does Stag Arms have instructions or a video on how to install the kit?
A: We strongly recommend having a gunsmith install the upper parts kit to prevent damage during installation.
My dumb self accidently got the right handed upper parts originally, which didn't work, realized quite rapidly when the dust cover didn't work. Bought the left handed upper parts kit and fixed my mistake in just a few minutes. Love my Stags.
