McCann adjustable gas plug

[albertacowboy]

I just ordered one of these from Ellwood Epps in Orillia, Ontario. M2 ammo is very scarce here in Canada and we don't know if the US government will allow the new Federal or Hornady Garand loads to be shipped across the border. In addition, I heard that the McCann stocks currently in Canada may be it for good, as it may be that this item may also not be shipped across the border in future. At any rate, an adjustable gas plug seemed like a wise idea for Canadian Garand lovers like me.

Can anyone give me any information about their experiences using this item with typical .30-'06 ammo? Many thanks!

i have the one made by Clint Fowler. it just uses one adjustable screw so i made some more screws with different size holes in them like the McCANN system and they work very well. yes getting the McCANN system was a wise move on your part. HTH

The McCann plug is great for skowing down the action and reducing wear and tear and improved accuracy in the M1s I installed it on. The greatest benefit is in rifles with new or in spec gas systems which have lots of extra power available (too much for non-combat use). It may not do much in a rifle with a worn out gas system, and some of these may short stroke if any gas is bled off. Be sure to have a full cleaning kit or weights in the buttstock and make sure to pull the rifle into your shoulder with good form for reliable operation.
