    No issues installing this gas block. Everything fit just like it’s supposed to. Finish inside and out is smooth, non-marring.

    Pins were to big for the gas tube and my AR has trouble cycling through now. If it doesnt get better after 1000 rounds I’ll be making a different review.

    Fit perfectly and fits inside floating handguard perfectly

    My new micro gas block is exactly what I needed! I recently upgraded my hand guard to a low profile 15” m-lock free float style. The previous installed gas block wouldn’t accommodate the new hand guard. No worries because 3CR Tactical had what I needed! Price was right and delivery was fast! Thanks again!
