    While spring length might be an issue lubing the action spring usually does the trick. Cold weather wreaks havoc on guns, especially those that are towards the edge of reliability. I had to do the same as Jay with a 16" Noveske N4 Mid (H2 and Wolf) and a 11.5" DD (H3 and Wolf) to get 100% function.

    Sluggish is inherent in that config.

    Going to a lighter lube like Remoil for the cold might help as well. Or Mobile 1 0W30.

    I was going to say measure/change your action spring but I just re-read and saw that you did that. Cold weather can affect elasticity which would lower your spring constant but I can't believe that it'd be a problem on a new action spring.

    Principles matter.

    I areas that "aint supposed to get lubed" I typically use a silicone spray lube. that tends to help assuming the area was clean and dry to begin with. make sure your parts are compatible with silicone tho.

    I kinda dumped a lot of the fancy go fast lubes (twl, militec, CLP, LSA, Wear check, Weapon shield, White lightning etc etc..) in favor of a simple quality synthetic motor oil like a 0w20 in winter, and a heavier 15w40 in summer.

    for grease a little product called Hob-E-Lube has one of the highest shear ratings you can get in a grease. It's used in model trains where the viscosity cant be so high that it slows everything down but it must have a high film strength. Some engineer somewhere checked the specs and tested it for use on the SKS sear which is difficult to lube and make smooth with typical greases. It's cheap and awesome.

    funny thing tho... I still use tetra gun lube to smooth up any action that is giving me grief. it's amazing what it does.

    I wonder if the gun parts are shrinking and causing binding due to temperature change. some attention to wear areas with some polish (?) might help.
    My capacity for self deception is exceeded only by yours.

    Doubtful.

    40-50 degrees is not cold. It might be cold perceptually to you warmer-climate guys, but it's not cold for the operating system. Your gun should not require any lube adjustments, special applications, or any change from normal PM at that temperature. It's performance should not vary at that temperature. If it does, and you are using known-good GI spec parts, your gun is broken and needs more detailed in-person inspection and diagnostics that can't be done via the net.

    If we were talking about temps much lower than that, freezing or below, that might be a variable. Up here in the northern tier, too many guns run well without special treatment to even think about temp in this case.

    Not sure when I'll be shooting at night next, hopefully soon though. I'm just gonna play with things one at a time. Now that I cleaned the hell out of it and also changed the spring, I'll see how it goes.

    If trouble arises, I'll wipe off the BCG quickly with a rag and apply regular Slip 2000 lube instead of the Slip 2000 EWL. Wondering if the EWL might be too thick, although that doesn't really make sense to me considering it's not even close to freezing temps. But worth a try I suppose. Then the next step will be lubing the buffer spring if needed.

    Just in case I'll also ensure I use several different mags if I have an issue, before doing anything. Not sure if dirty mags or weak mag springs could have any effect or not.

    After my next range trip at night (I swear to Christ it only happens at night for some damn reason!) I'll post my results. Thanks everyone for your input.

    Interesting thread, thanks for your candor with the problem OP.

    This might really steer me away from the 14.5 middy as I often venture into the mountains in 0F weather when shooting in the winter (no one else is crazy enough to go in such weather so I have the places to myself).

    Perhaps a 14.5" carbine would be better suited for the colder climates as it is less sensitive to the pressure variations stemming from lower powder temps?

    An interesting side note, I have fired my 10.5" LMT upper in as cold as -22F weather before, and have fired Colt M4s in extreme cold as well using LSA as a lube and never had any issues.
