What barrel was this?

[Beerhunter]

Be very careful using parts off that gun. Those white stripes look awfully like DP markings to me.

I think he plans to turn it into a dummy so being a DP isnt a problem.

[Grizzlypeg]

Lots of DP markings on it, stamped into both the metal and wood. Did they make DP's from out of spec guns?

[Peter Laidler]

Generally, yes Grizzly. Worn out guns too but in the UK, they also made them from the obsolete Mk1's too but not necessarily. There were also some made from worn out 7.62mm L4's

And theres another variation to find.

Would I be correct in thinking that (It has been mentioned before I think) the main reason for DP ing a Mk1 is down to the worn gas cylinder, as its a PITA to change.

[Grizzlypeg]

I tried driving the tapered pin out that holds the short bit of remaining flash suppressor on. Ground the left side flat then used a good punch and pounded and pounded. No movement. That sucker does not want to come out. As the flash suppressor remnant is trashed from having been cut off by the demiller, I simply drilled out the pin. Tonight I will try heating it up and seeing if I can get it to come off. A few good whacks with a hammer did nothing last night. Its on there solid.

[Peter Laidler]

We have been known to weld a large nut to the gas cylinder them just heat it up to red heat, as it would get in service, then just wind it out with what we in polite Armourers language call a fxxxxxg big spanner. The pin wasn't usually a problem using a press and a short stubby punch. Usually an SLR piston. That shifted the baxxxxxs!

[Grizzlypeg]

I thought of trying a press, but I thought the impact of a hammer and pin punch would have more ooomph.

Grizzleypeg,

If you have access to it, get yourself a can of "PB Blaster", it's a penetrating lubricant we used in auto repair and it works like the dogs bo*****s. Soak down the seam where the parts meet, tap it with a hammer and let it sit. I used this on a stuck trigger guard screw on a pretty grungy Webley Mk VI I'd bought that just wouldn't budge, then forgot about the thing for a month. When I tried it again the screw bloody well nearly unscrewed itself. No onwer of old firearms (or old cars) should be without this little wonder. You should be able to find it at Home Depot, Lowes, Advance Auto Parts, Auto Zone, Napa, etc.
