Hi all,
I was just curious as to how often do owners do a complete teardown and cleaning of the gas system after shooting their m305's? After every trip to the range, or is it really necessary to be so thorough every time?

Many thanks"
 
I only do it about once a year. But thats only putting through about 2000-2500 rounds. I just use Hoppes Mpro7 gun cleaner to cut that carbon out with a nylon brush, or a toothbrush. Make sure when you assemble it, that the gas affected parts are dry and free of oil and such.
 
The manual says to do it "infrequently", basically only when the rifle stops performing. Frequent disassembly can wear out the parts and cause further problems.
 
Thanks guys,
I'm so used to stringent cleaning after shooting corrosive ammo through my Russian rifles, I was carrying it over to my M305. I shoot non corrosive Malaysian 7.62 NATO or Federal .308 through my Norinco, nice to know that I don't have to be so meticulous...Thank you!
 
After about 60 rounds, I tore my M305 down and was surprized to find barely a trace of carbon in the gas system or on the bolt head. Most of the carbon was limited to the gas piston head. In comparison, the SKS's I regularly fire, with their loose-by-design tolerances, get dirty everywhere really fast.
 
The M14 gas system was designed to be self cleaning (unlike the FNC1A1 I carried, what a PITA). After a match I would remove the piston and wipe it down with carbon remove like USGI Bore Cleaner ($ 2 a bottle at gun shows). I would reassemble and then next range visit, add a couple of drops of USGI bore cleaner (Shooter's Choice will work too) and then fire the rifle. This process, blows the loose carbon out.

I add a couple of drops of bore cleaner in the "weep hole" found UNDER the gas cylinder wall, immediately ahead of the front band. Cycle your op rod a couple of times and then FIRE away! :D Clean gas cylinder!

NEVER lubricate your gas cylinder unless storing the unit for longer periods of time, and of course, wipe it all clean before shooting! :eek:

Hope this helps the addiction.

Cheers,
Barney
 
that self cleaning thing and the sights were the two biggest advantages i found in all the time i was "in country" - the americans have NEVER been big on maintaining their weapons, unlike the soldiers of the empire- if they under do , we OVER do in big letters- so they design their weapons to need the least maintaince as possible-yet they still EXPECT EXPERT marksmanship from that gun when it's used- look at anything they've fielded since the garand- as an old d.i told me, "expect the troops to be morons, and you won't be disappointed"-in other words, EXPECT PYLE, and be pleasantly surprised when something else shows up- or in todays venacular, expect GUMP
