Hey......, there you go. The power of the Forum for you C130! The original Mk2 butt slide side walls were reduced in thickness to .6" from the radius, and radiussed deeper, immediately in front of the trigger guard, milling forward to a similar radius, ending and almost following the front radius at the front end of the ejection opening. Effectively converting the Mk2 butt slide into a Mk3 gun lightweight butt slide. Additionally the bolt type Mk2 pistol grip retainer was converted to the Mk1 or 3 type using the hollow large diameter bolt with a new threaded sleeve brazed in place.
The reason in UK Military service was in the interests of standardisation with the existing Mk3 and L4A2 and 4 guns of course
But, hey....., with what you have done so far, this is just cosmetic stuff! And I doubt that the export buyers bothered with this
Well that's easy enough. It was built on a lower with the MKI type handle. I have a MKIII I can basically copy the contours off of and presto. I will have to give Brian a call on Monday and see if we can't work something out. Thanks guys.
If you're starting with a Mk1 butt slide then don't forget to shorten the front 1" or so, as per the Mk3 gun type you are copying. Great work so far. If I hadn't seen it, I wouldn't have believed it after my experience doing the same!
Maybe just caught up on something internally as it should remain forward under the control of the spring loaded plunger in the cocking handle. Worn spring plunger and the little vertical cam-pin. They get flats worn on them
Harry mac, I enjoy mine, (Inglis Mk.II and Enfield L4A3). They are both post '86 dealer samples since I can't afford to shell out $25-30K for a transferrable one. I feel lucky to have them even though they are government rentals more of less!
I notice that the charging handle seems to catch or bounce during firing.
Yes, I have noticed that also. That's Joe's transferable converted/ running 54r. It was test day and on the lowest gas setting it was still way to much. It also has the MKI single return spring. A MKII spring has since been installed and we are trying to figure out how to choke the gas down more. Evidently the mag didn't run as we'll at the Marietta shoot so back to the drawing board. If I could get my hands on some factory drawings for the 303 mag it would be helpful. We want to modify the follower and having the original geometry of both mag and follower would be very helpful. Peter?

Sorry Brian, it's been chaotic. Wife's been traveling, I am an airline pilot, so with two little ones it's been crazy. Beautiful pics you sent me last week. I now want an L1. Any word from your engraving buddy?
I don't have magazine drawings but given the availability of magazines and platforms, the actual feeding geometry shouldn't pose too much of a dilemma if you use a few platforms to practice with. The only 'problem' I can see is with the fact that the round is slightly shorter than standard so there is a longer what we call 'no-mans land'. That is the time that the round is being pushed forwards IN the magazine until noses out it is cammed downwards and left or right and into the chamber.
The 'problem' as I would see it is that because the 7.62R rim is much thinner, it is sat inside the same depth cartridge seating in the bolt and therefore the now tightened up (by the extractor stay don't forget.....) extractor cannot exert the same leverage on the rim while the breech block is rotating downwards to unlock. In short, and cutting out the crap and waffle, you're short of most of the primary extraction.
If I had to reduce the excessive 762R gas, this is what I'd do - to a spare barrel first. Drill and tap the gas port slightly oversize. Insert a hexagon headed grub screw with a slightly smaller hole bored through, making sure of course that it is well clear of the bore of course. Back it off until it allows you to insert the gas regulator which will initially support the new undersize vent. Now test fire, adjusting the 'new' gas hole in assorted modified grub screws until it runs well on gas regulater hole 2. Leave it there and within a few more test firings it will be rock solid. (added a bit later..... There is a LOT of meat on all of the barrels at this point, certainly enough to drill and tap. Additionally, this part is also reinforced by the gas block sleeved on too don't forget
The last part is to never tell anyone that I suggested this dire, seemingly bubba course of action! But the only way to get less gas is to look at Boyles law s of gas. All you are doing is what everyone who uses blank firing weapons does every day. We used to have a couple of blank firing AK47's and an assortment of different sized apertures in the various BFA's.
As a matter of interest C130 Pilot. I've heard of a C-130 and jumped out of one 26(?) times, - but what is a C-310?
