You made me investigate the gas tube thing...
Measured and compared (one of them anyway) mine to known good gas tubes and noticed no meaningful difference at all. Found a thread here about it and noticed that the guy complaining gave no numbers / sizes at all for what he claimed was a 'thin' tube. No OD or ID given at all in that thread... Just complaining.
Not buying that story personally without some specs / data to back up those claims.
Did notice a 'G' marking on the barrels near the chamber that I had not noticed before. (Mark is almost directly under the gas tube and hard to spot)
Pretty sure that means Green Mountain made it. That is a good thing in my opinion... Absolutely love those particular Expanse barrels.
I looked at the Green Mountain website last night and could not find that exact barrel listed for sale or any mention of it anywhere so I am 'guessing' that it is something they made for Colt to whatever specs Colt gave them?
Those single shield, slim hand guards are 100% Colt parts. Colt 'Carbine' Hand Guards to be exact. Love the feel compared to the M4 fat oval type so... Bought a small pile of them to replace the OEM stuff on other Colts with. For me and for range use they just feel better in my hand.
Have not tried to melt a set yet and have no idea how much it would cost in ammo to do it.
