What is this orange stuff?

[Texas10]

I see what looks like the same material between the barrel threads and action. Might be epoxy used to make a feed ramp in addition to setting the barrel into the action. Looks like your dad's got his work cut out for him

Update. We are fairly certain its an epoxy of some sort. Dad removed all the epoxy from inside the receiver, unless is shoots like crap he does not plan on pulling the barrel. He ordered a set of go no go gauges that should be in tomorrow. I have a attached a photo of where we currently sit. If you guys are interested in what he had to do to the bolt I can post those photos as well.

Nice looking gun. My concern is that some epoxy can "soften" when heated up. I wouldn't use it for long strings of fire. Heck yeah, we're interested!

Most epoxies don't start to soften until the temp gets north of 550 degrees F. Unless this guy's belt-fed, I don't think it's possible to get the chamber section that hot.

I'd be more concerned with the reason behind using epoxy in the first place. I can't imagine using epoxy for a barrel installation out of preference.

Did you order 308 win gauges ot 7.62 gauges . They aren't the same . So if it swallows your 308 win no-go , don't be suprised . Check out the headspace dif

I did not know that. My father tried last night using 308 and I do know the bold did not close on the no go gauge. I will talk to my father when he gets home and find out more.

I've have had pretty good luck calling Remington. If it's old, you may only get original caliber, but that is something.

Usually yes , esp if he took his time .
There are date codes on the barrel that may narrow your search . Being a repeater 40 X 7.62 nato it may have the stripper clip guide . But something is odd the receiver ring cut out , usually for say a 30-06 or any long action cartridge . It's been awhile since I had 308 factory repeater 40x so take with a grain of salt .

The receiver ring cut-out is not "odd" - it is standard on repeater 40-XBs, so the rifle can be loaded with stripper clips. The cut-out and stripper slots are cut in the reciever when it is made - so when you get a repeater in 22-250, it will have stripper slots and the ring cut-out.

See pics of my 40-XB iron sighted match rifle... it is self explanatory.


The orange stuff is an old epoxy bedding compound called "Micro-Bed" that ooozed up through the front receiver screw hole and got smeared around. It won't hurt anything and it can be picked out. The barrel has not been set back.

Glass bedding has been standard procedure for accurizing a rifle since the mid 60's... it is VERY OLD technology! Haven't you ever bedded a rifle??

If it did Not close on the no go , it should be good to go . It was if it closed on the no go . There's a date code on the barrel . Google Remington barrel date codes for location and cypher . BLACKPOWDER the letters all represent a month or year , I forgot !

Methinks that J was inferring the epoxy was used in the threads of the barrel, not as bedding, John. But I will let him defend himself, which, by the way, should not be necessary. He has significant experience with such things. As I read this thread the conclusion that the orange "stuff" was epoxy bedding came after JLT and others were discussing the possibility that it was epoxy used in the possible replacement of the barrel or other "fixes".

And bedding isn't that old...some of us here recall grinding salt peter to make our smokepole go boom....

Respectfully,

Snert

Probably many more than you have . . . I wasn't the only one expressing concern over the use of epoxy in fitting a barrel.

I've never had bedding compound end up inside the front receiver ring. I must know what I'm doing.

As promised here are a few photos of the bolt work that had to be done. When opening and closing bolt it would hang up in the action. Some of that we thought was caused by the epoxy in the action putting pressure on the bolt from the side. Sadly we were not that luckily because as you can see from the photos the majority of the problem was caused by the cocking piece on the bottom of the bolt was not aligned with the groove in the bottom of the receiver.

Photo 1 (1729.jpg): The top bolt is a good Remington bolt, the bottom is the 40X bolt. If you look, you will notice the notch that the cocking piece sits in that helps align it is missing from the 40X bolt. We are guessing someone removed it to help open and close the colt.

Photo 2 (0541.jpg): Indicating the bolt in

Phote 3 (5459.jpg): Back of the bolt

Photo 4 (0313.jpg): Finished. Everything is back to being aligned properly but we have a number of concerns. One being how much of the heat treatment is left and the other is that gap.


We are still debating on if we plan on having a second bolt built for this gun. It kind of depends on how it preforms on paper and how you guys things the current bolt is functional.
