so, assuming 2 rifles, same everything except one piston one DI.
and assuming same pressure in both barrels, you guys are saying that the rifle that vents the gas used to run the action of the rifle DIRECTLY into the action of the rifle is cleaner than the one that vents the gas used to run the action up near the front of the barrel (nowhere near the action)?
and then adding a suppressor to both actually makes the piston gun even worse?
seems very odd to me.
where is this extra gas coming from on the piston gun?
I mean, the DI gun actually dumps extra gas right into the action on top of the volume of gas coming back down the barrel.....? isnt that extra gas that is not present on the piston gun?
I have shot suppressed DI guns to failure, had to mortar the action open and bent the charging handle. I even started carrying a little bottle of oil to classes to keep them running. that disgusting sludge, basically polishing compound of carbon and oil, is a problem, continued applications of oil is only a temporary band aid.
I got sick of it and bought a piston gun, havent had that problem since.
not to mention how much nicer it is to not have all that gas in your face when shooting strings, you know cause, so much more gas is coming down the barrel than through the gas tube..... I know, disclaimer, yes some gas still comes back into your face on a suppressed piston gun, but NOTHING even close to a suppressed DI gun. not looking at you gas buster charging handles.
which is also strange, since more gas is coming down the barrel than the gas tube, right?
on a seperate note, I always found that the dryer the better on DI guns, oil just captures the filth. grease seems to work better for me on my DI guns. tekmann2377 and JoeZ nailed it on that recipe, lot of guys been using that for a long time and it just works
decades ago a company (cant recall who) sold a dry lube in a black spray can that dried white in the parts and you could wipe the carrier film off and it left a slick dry coat of lube on. that shit was magic, regardless of the temps it just worked and kept the rifle way cleaner. wish it was still made today.
