well as any of you that own a M-14/M1-A know or should know ............they need grease and lubricant to make them function. yesterday i went to 2 shops looking for TETRA gun grease. no luck. found some shooters choice grease which goes up to 350 degrees. TETRA goes up to 750 degrees. some guys use simple waterproof wheel bearing grease much to somes angst(purists). i started reading into temps tested on various components under rapid fire. apparently the op rod spring gets up to 500 degrees under combat wombat pressure. this came off of TUBBS website, and thats why they use chrome silicon springs for all of their builds. another interesting note is how if i were to use the grease i bought(shooters choice 350 degrees) its obvious it would SLOUGH OFF of spring op rod op rod guide under heated conditions. soooooooooo...........my search for TETRA GUN GREASE CONTINUES> i can always get it air bombed into by brownells or midway but i'll try again today. its HOT AS HELL HERE and buzzing around finding components in a a/c vehicle beats the hell out of being outside. one of the keys of a smooth m-14 is heavy grease along rails where action slides and all over along op rod and op rod guide and spring. this makes a HUGE DIFFERENCE and thats why i want TETRA!
i did manage to remove my gas port threaded cap and replace it with the sadlak national match piston. 62,000 swabs and 1/4 gallon of hoppes #9 got it clean as can be. re installed sadlak piston flat side up(DRY) and put grease on gas port cap threads and gave it a snug with combo tool and its happy as a clam. just cleaned oem piston with my usgi drill bits and brake cleaner. man what a mess! they certainly get carboned up quickly. or was it owner/operator failure to clean after last shooting session. NOTE TO SELF: clean piston as well as bore EACH AND EVERY TIME YOU GO SHOOTING...............wayyyyyyyyyy easier to clean gas port and piston then every 2 years.
i was told DUFFS book on m-14's is a good one to own as far as tricks of the trade. my tricks have come from my ffl/smith/and arrington and the m-14forum.com. they have some great info on about every and any problem or upgrade with a m-14. some real good info re: testing of new fangled ops and product items and believe me they aint kind if a product fails and/or is a POS! some of the GURUS OF M-14's have some great articles there. very informative.
