Troy low pro gas block?
So is the gas tube closed on the block end because the hole for the tube is open through and through. No not the roll pin hole, the gas tube hole.
I have never installed a gas tube so I'm am clueless on this one.
Gas tube should have an open end facing/going into the upper receiver..
The closed end of the tube goes into the gas block..
Some gas blocks have closed ends on them.. matters not really..
I've used both open end gas block and closed end gas block..
Keep the roll pin hole nearest the barrel muzzle when installing.. I've seen people start the roll pin on the tube off the rifle then realize the tube was protruding a little long into the receiver..
Thanks a ton. Just the info I needed.
