I trust School of the American Rifle more than these nobodies providing no valid criticisms. Good work.

Good work. Ignore the peanut gallery.

Good video. Seems most neg comments didn't understand why

Simple to the point thank you!

SOLGW who also has thermal fit upper just did a video a few months back saying they don't have time for hair dryer or torches and to just beat it on carefully with mallet being you put muzzle end on something "softer than the barrel" their words. I've done exactly the way displayed with the 5 or 6 rotations under the heat and installed first few uppers I placed barrel in freezer. But that ends up creating more steps for the prep

I watched that video and it reminded me of the time I saw a gunsmith at a show driving in pins with an adjustable wrench. And the time another gunsmith kinked the recoil spring in a 1911 disassembling it out of order. But I did buy a SOLGW combat trigger and it’s fantastic. If they whacked on it I sure can’t tell.

You can also put the barrel in the freezer

I have experimented with freezing the barrel but the humidity condenses on it instantly and any moisture will promote corrosion, especially between dissimilar metals. I opt for heat and bedding compound to keep that space dry and sealed.

If you can rotate the receiver and get it to slide up like that, it is not an interference fit at all to start with.

That’s exactly what I was thinking. You should not be able to get it on at all

Chad is that you?

What is the critical temp, if you don’t mind me asking?

@GunFudded

Ай бұрын

The alloy (7075) is heated, quenched, and aged at an elevated temperature in the manufacturing process to achieve the mechanical properties of the T6 designation (7075-T6). Critical temp is when it’s heated enough to affect those properties. Since it’s quenched at 470°C staying as far away as possible from that with a 2000°C torch is the objective.

If you can slide that barrel on without heat or cooling, its no interference fit. Anybody who says otherwise isnt any real type of machinist.

To each their own. Wtf

Buy a better upper and theres no need to bed it

I would argue that adding retaining compound to the extension of a barrel going into a thermal fit upper unnecessary. Think belt and suspenders 😅 But choosing to bed a barrel in no way indicates a “low quality” upper was used.

Stop buying cheap trash. Thermal fit IS better

Yep. Some use a belt to hold the gut in while the suspenders hold the pants up. The nut will hold it and the compound fills the surface and seals, eliminates any chance of corrosion by condensation infiltration, and locks the metals together when they expand and contract. Frequently used for bearing seats, injector cups, etc. in other disciplines.

@@GunFudded I’m pretty by the book and the only thing on my barrel extension is Aeroshell 33MS. If I were building a varmint or competition gun, maybe I would bed it.

All that nonsense is not needed😂 slide the receiver onto the barrel extension and lock it down😂😂😂😂😂don’t know why you people make such a complicated deal over such a simple process 😂😂😂😂😂

And just wrap your hand around the threaded part of the upper to warm it slightly and it will slide right on the barrel extension. No lube or solution needed.

Because not everyone wants “okay” some people want everything they can get out of a gun What you’re saying is like comparing a f class bench rifle and saying it’s too much and that your 400 dollar rem 700 is just as good

Try with a bcm. Won't happen

There's no point in bedding the barrel, especially with a liquid. You squeeze all that stuff between the face of the receiver & barrel. All you need to do is Lap the receiver to have the barrel trued to the receiver. Torquing the barrel nut will take care of the rest.
