Nope, I don't have any M14's at all. I like building , tweaking, competing for a match or 2 , then selling them. You have to understand how I just love working on them, well the REAL USGI M14's that we bought for $ 400 back in 1986 when Israel was dumping them into Canada. We could buy USGI TRW Brand new in the wrap for $ 35 at local Toronto gun shows or AJAX or Hamilton or Scarborough or Ancaster.
With Service Rifle matches, I just shoot an AR... cheaper to feed, brass is everywhere Winchester White box shooters congregate.
Okay, back to the gas cylinder lock tool.... I just used my left hand while the right hand cranked on the gas plug with the combo tool wrench end. Anything tighter was not necessary.... biatch to get off.
Cheers,
Barney
