After a long overdue cleaning of my Universal M1 carbine, I noticed something that I hadn't noticed before..
Inside the stock where the "tappet" on a GI M1 would usually reside, there is a buildup of residue (as the picture below illustrates).
I was under the impression that in order to cut production costs, the commercial Universal M1 did not feature a tappet-assisted recoil operation, but with the redesigned bolt carrier, was recoil-operated only.
There is something that strongly resembles a gas port/tappet housing with an immovable 3/8" diameter object resembling a piston that looks to extend out of this housing by 1/8".
Is there any knowledge of Universal M1s that were assembled using barrels with modified (read "disabled") tappet systems? Another clue that leads me to believe that this indeed may be what it is would be the more than usual residue build-up around the area of what would normally be the tappet housing (bottom of barrel in that location, recoil spring guide rods, etc).
This is one of the better trades I made, having procured it several years ago by the trade of a Marlin 60 (since replace with a newer model 60) with old Redfield scope and $50 cash.
This extremely accurate carbine has never jammed out of the 400 rounds of PMC and Armscor FMJ I've put through it and is quite possibly the cutiest shoulder-fired firearm I have.
This carbine has sparked my interest in the M1 and someday I'll look into buying a GI issue. However, right now I'm looking for answers for the one that I do have. Is this a modified/disabled tappet system showing signs of a break down? Thanks in advance.
