Non Invasive Mod Removal?

[Klenchblaize]

Lot of faffing about, angle grinder, re thread, re crown - job done. Give your mate the bill and six lace holes

Try a Bluepoint pipe cutter and enjoy accuracy-enhancing chocking.

Cut it off , have done a few like this, last one was a man from Devon who moved here, he rang sportmans to complain

Like @Tim.243 has said, I imaging the captive nut has broken away from the rest of the mod. Your description suggests this is most likely.

I wonder .... how do you clean a barrel properly with a mod on?

You start by taking the mod off, hence problem number 1

 

[Jvoelcker]

But the bullet and cut the mod off.

The bridge/adaptor was pretty tight on, but bring stainless wasn't corroded on.

Crown doesn't look great, but solveable...

Well done. 60 posts later the gunk dunk spray gang have an answer.

That'll about weld back together. Bit of wd40 round it all and she'll be grand for the next 10 years!

I was hoping to avoid the inevitable, but one or two useful posts explaining the likely internal structure left only one option.

Hmmm. Interesting postmortem and a good example for all of the reasoning behind removing the moderator as soon as possible after shooting.

Valve grinding paste smothered atop a suitably profiled wooden dowel, to match the bore diameter, and then spun in a drill on slow speed would be worth a go before involving a Gun Plumber.

I religiously remove mine and strip it after every trip out and use coppereaze on all joints so a breeze to undo.

Yep - funny thing is I just bought a Stalon moderator after years of using an Utra 5. Clearly the Stalon requires a tad more maintenance than the Utra including lubricating the joints whereas the indestructible Utra just got a squirt of WD40 despite long range days with the 6.5x55 and .308. Still, mustn’t grumble…..

I've seen quite a few American forum posts where they swear by using a round brass slot screw head in a hand drill. The brass is softer than the barrel and the slot holds the valve grinding paste while the shape is about right for a nice smooth crown.

I'd definitely try it on that rifle first more as an experiment to see if it actually works and then if not nothing is lost and some knowledge is gained before sending to a gunsmith.

I've thought about some of the DIY options, but have a pet gunsmith why can do it whilst I wait and my mate is paying anyway so his problem

 

[trickie]

Great news that is has been removed and damage in minimal

 

[GWP]

How far down the barrel does the rust or crud go possibly a cut and re-thread will be needed

The threads only have a tiny amount of rust which will soon shift with a tap. Just need to get the crown sorted really.

 

[Will the chippy]

The crown doesn't even look too bad. The pic isn't the best but still...

 

[newsatten]

sit it in a jar of diesel for a couple of days and then try again

Definitely plus one regarding the diesel!!!
Fabulous stuff for this sort of thing !

Having said that the fact it moved then just spinned does suggest a pulled or stripped thread !
And how the fu— can you not clean a bang stick for 7 odd years!
