DIY: Barrel Swap

[Jettheterror]

Hey Guys,

Did a video for you on how I swap out my barrel on my precision rifle. I know for me it was a dark magic that only gunsmiths and witch doctors could perform because I hadn't done before and I couldn't find enough visual information to wrap my head around it all those years ago. Hope this helps someone out.

I don’t know what rifle you’re working with but check your headspace before you shoot. I recently started threading and chambering my own barrels. It isn’t rocket science but it does take some skill. Stay safe and Good luck

It's in the video. those barrels are made to crank on and shoot.

That doesn't mean you don't need a gauge. Verify yourself, because people make mistakes.

I didn’t watch it. I know how to install a barrel. Regardless the barrel, I wouldn’t want someone to skip verifying headspace before firing it.

they're called prefits for a reason. Those barrels screw on and the headspace is right. That's how they're made

Bud, I don’t think you’re gonna convince people telling you about a safety step they feel is important that the safety step is in fact not important.

Especially when that step costs no more than $70-80 per chambering, and can be reused indefinitely.

I understand. The whole premise behind shouldered prefits is they screw on and shoot. But you go ahead and have that shouldered prefit headspaced if it makes you feel good.

You're exactly right and anyone who does not check a new prefit barrel with the gauges is on a dead fools errand.
Manufacturers make mistakes and that mistake could cost you your life ......

so please enlighten me. I'm actually asking a serious question. How do you headspace a prefit barrel? What changes are you going to make?

You bet your ass I’m checking headspace on a shouldered pre fit barrel. Headspace range is very small. Very easy for a small mistake to happen during machining. I would bet every supplier of prefit barrels advises this step. It isn’t headspacing a prefit but checking the headspace is correct. Well worth the price of 2 gauges.

You don’t headspace a prefit, the barrel manufacturer does. You *check* headspace on a prefit, and if it’s good, perfect, you never check it on that action/bolt combo again. If not, you call the manufacturer or vendor and tell them they shipped a faulty product, which is hardly unheard of in the wide world of business, and you want a refund or replacement.

Makes sense. checking is different than headspacing, which is where I guess I misunderstood. Point taken. Don't trust prefits.

nice welder... do they have torque specs for the barrel vice? or do you just tighten as hard as you can?

I tighten it till it won't slip in the vice.
