Questions & Answers
Is this barrel drop-in or must it be headspaced and fitted? Expert Answer

I recommend you check headspacing any time you assemble a firearm. Ensuring proper headspacing and fitment may be an a little bit of time consuming extra step in assembling your rifle but can prevent you from having some series issues down the road.

Beautiful barrel by BreezyBear, Verified Owner, December 11, 2023
Got this for my new Roam ultralight .308. Looks great, hand lapped barrel was easy to clean and groups were right at 1 moa using ball ammo. Can't wait to stretch it out further with some good ammo.
