View Full Version : Technical: Setting the gas regulator
July 08, 2001, 18:11
OK guys,.... I'm a new member to L1A1 ownership, so sorry if these questions bore the old timers.... ;)
Today, I had it out for a brief while... the first 10 rounds through the mag worked fine. After that, I went to manually feeding them one at a time..... that's when the problem started: The shells were ejecting halfway and getting crushed by the bolt on the return. Would too much oil on the gas rod do this? The gas port is set to 4.... where is it closed (100% to the piston) and where is it open? If it must be closed any more, would this be a sign of some worn parts? :confused: What makes it odder is that when I went back to putting 2 shells in the mag, it fed and ejected fine....
The ammo I'm using is British ball ammo that's fairly fresh and has performed well in other rifles.....
Thanks in advance for any and all help!!!

DO NOT PUT ANY OIL ON YOUR GAS SYSTEM. PERIOD.
Dry it completely before firing. DRY IT.
The system is intended to feed and extract over the magazine. If you hand feed, that's a no-no. Garand shooters have done this for years, for two reasons. Just lock & load from the magazine.
GET ALL THE OIL OFF the gas system.
If you'll go to the FAQ, you'll find out about gas adjustment. Search.
Meanwhile, short version:
- CLOSE the regulator all the way forward against the gas block.
- OPEN it one FULL turn
- Insert mag w/ 1 round, fire
- CLOSE regulator one CLICK and repeat 1 round magazine until BHO (Bolt Hold Open) functions.
- CLOSE the regulator ONE more click. Try several magazines.
As the setting wears in, you may need to CLOSE one more click.
As long as you don NOT change ammunition, you will not have to adjust the regulator until you have failed to clean it after several hundred rounds.

Thanks for the response!! :)
Since the last note, I've cleaned the gas system on the gun. It took about 35 patches to get it cleaned :eek: !! It doesn't appear to have been cleaned for quite some time, if ever.... funny how some people buy these things and never clean them.... and I should've cleaned it BEFORE I took it out...
Now, my gun doesn't have an automatic bolt hold open.... it's on the 'things to do list'.... How could the regulator be set without this feature? This gun of mine appears to be a Century thumbhole with an inch upper and a metric lower. Which automatic BHO would work for this gun?

I figured consistent 4'-5'ejection, would be about right to adjust without a bolt hold open. There is a thread somewhere about this.

Off the subject a bit I'm afraid.
Ted I like the tank.
Trying it out or is that going to be part of your EMD II from now on ?

My last personal office, and my approach to life. I commanded an Infantry Company, Tank Company, and Cavalry Troop. The Cav Troop has nine M1 and thirteen M3.
Speed, Mobility, Firepower!
G3: Your BHO-less rifle should eject just where you've described. 1.5 to 2 meters out, at a 45 degree angle from the bore/ejection port. Any BHO will 'fitta fine'.

Thanks for all the info guys!!
So the next step for the BHO will probably be the 'for sale' boards..... that is unless, one of you fine folks just so happens to have an extra one floating about...... :D
