Upper swap and headspace

[Sledge1]

I'm wanting to install my current barrel/ bolt into a new Seekins upper/lower. Will the headspace remain the same or will that change? I'm thinking of getting their new upper and float tube setup and the way the barrels install in their uppers is totally different from my current rifle.

Thanks.

The headspace will not be affected.

The bolt headspaces to the barrel and indexes off of the barrel extension - if you don't have issues now, there shouldn't be a problem after. But with the cost of a seekins upper and tube, I'd just get all new parts and build it once.

Re: Upper swap and headspace

I've already got a 6woa rifle built, but it's on a Rock River upper /lower. I'm wanting to swap my Krieger barrel over to the new Seekins stuff and maybe to a plain .223 on the RRiver .
