Slip fit barrel question?



Log in to see fewer ads
Are any of you folks using locktite or similar when re-installing slip fit barrels?
I've changed a few barrels out,but have never used any goop!

Thoughts???



Thanks!

I tried it on a 77/22 but I don't recommend it. It locks the barrel in and it didn't really make any significant improvement in accuracy. That seems to be more of a chamber cut and head space issue.

Yeah thanks!, I've got a couple 77/22's also! But I'm mostly talking about Mossberg shanks here!

Hey Ross. Are you trying to fill up some slop between the barrel and receiver? I never have but If I was I,d use one off the non permative ones first to see if it worked.

Don't know about slop yet. I have a barrel coming end of week. Just want to do a good job getting it secure to receiver!

Its a 144 series rifle. Not an LSB...

Maybe this will help.

Maybe this will help. Every BOLT ACTION Mossberg barrel that I have ever removed looks like this. It is the slip/press fit style as shown below. If the barrel is a bit loose and you want to tighten it up a bit without locktite find a small punch and do a circular pattern of small UNIFORM punch marks around the entire circumference of the barrel shank in the "knurled areas". Generally speaking more punch marks will = a tighter fit. you could also do a double row of punch marks, if a tight fit is desired. Just hope you don't have to press it back apart. I found one REALLY tight LSB that was quite upsetting. Hope this helps.

God Bless, Frank.

Yeah,I did the punch thing on something automotive years ago! Might have been on a spindle so race would be tight???

Thanks! I'll sure keep this in mind!

I never had any problems with fit. So no I don't use anything to take up slop. I have used the punch on dovetail sights and such if they were loose.

I used Loctite 242 on a loose 10/22, it gave just enough fill and grip to stay put, and you can break the bond with a few swats of a rubber mallet. I did use 620 on a Tac-Sol barrel but had no plans to ever remove it. It still can be removed but you'd have to heat it before you beat it.

I don't know if this will help...

But i used this compound on my AR-10, between the barrel and the receiver, to take up any slop. It was recommended by another builder. My rifle shoots a number of groups at 1/3 MOA, so i guess it helped.

Thanks for this info! Sounds like something I'd use on my Flathead Ford.
Seriously,I'll keep this in mind!

Musta used ten gallons of that stuff in 30+ years of twisting wrench.
That little gal on the can had the nicest set of pins.
