How much was the gas piston undersized? Mike Sadlak is a good guy, and a sponsor here. If we came up with a target diameter, he might be able to make a small run for us. I imagine the best way to do this is a centerless grinder, which I do not have, but it ought to be dead easy to shave a few thou off for someone who does.
Love the pics and love the M14 as well. I have a Mcmillan stock just like the ones pictured. Does anyone have a build parts list for these? Id love to build one of these and use it for competition. Any help is greatly appreciated.
Can you please what the double lug and double torque screw is?
A double lug gun is one which has two recoil lugs welded to the bottom of the receiver, one located near the rear of the receiver and the other welded to the front of the receiver, angled about 45 degrees, forward of the mag well. The receiver is tightened to the stock with screws that are torqued into the lugs.
Legend has it that a double lugged gun requires a dedicated armorer to keep it properly tuned. LOL.
Shooter - To an extent, in that time period, yes. Older bedding techniques demanded an armorer be standing by with some bisonite. The slightly slimmer McMillan was one of the earlier ones in which they were experimenting with utilizing a metal stock liner. Put a thin layer of bedding between that and the receiver legs, or too little behind a rear lug, and you'll have bedding breakdown by 1,500 rounds easily, sometimes at random. Bedding compounds don't do well when applied in an excessively thin manner. Eventually they decided that it wasn't necessary and went to the newer McMillans.
Nowadays, with modern bedding techniques and full McMillan stocks, this isn't the case. The most common problems now are sights being sloppy or falling apart, gas piston cleaning, and checking torque screws daily. A pre-set torque wrench should be used on both screws before shooting every day, and the Big Team used to line up and get this done in front of the armorers truck.
USMC Grunt - Parts were mainly NOS USGI just very well fit. There's bolts of all brands, in house modified op rod spring guides, etc. Nothing special about the parts, plenty special with the old gun gods who made them, and the legendary rifleman that won with them.
Figured you all would enjoy seeing these. They are some of the last few heavy barrel, double lug, double torque screw rifles the Marine Corps has. They have some personality to them. They are a mix of 1/10, 1/11, 1/12 twist barrels.
Any questions, let me know! I cannot show serial numbers from the receivers, but other than that, its okay.
This last one is the part of the last Marine Rifle Team to ever field M14s across the board. The NM M16 was developed and fielded afterwards.
