View Full Version : G1 & Gas settings
September 02, 2001, 18:11
has anyone else had their G1 to the range yet?
I just took mine out and had to dial the gas setting down to 1.BHO needs replaced since it won't lock open after last rd.And the spring feels weak(BHO spring).
I tried several diff. Mags,and gas settings.
has anyone else had similar problems?

Well, make sure the gas system is spotlessly clean. Do not lube the piston head or gas block except for storage. Make sure the recoil tube and springs are spotless, and lubed only lightly w/ a quality grease such as Tetra or other.
Check piston head diameter: it must be at least 0.429" in diameter. And look for signs of leakage from the gas tube-to-gas block connection. Any fouling except at the regulaotr port and at the tube exhaust ports indicates leakage. This will reduce piston energy, and lead to short cycling.

I am trying to get mine to cyle on closed. No luck yet. Could be the piston. It may be the exhaust port is too small for real life use. I will have it sorted out by the weekend, I hope.

Ola Bill- the exhaust port or the regulator port?
FWIW (and so I don't do anything else stoopid!)- Is your gas regulator bleed port (in the sight block) too small? You got a carbine, or F/L rifle?
The 'exhaust ports' on the gas tube could cause pressure to hold up slightly if under-sized, or dump faster if WAY over-sized. But the bleed port in the block might be too small. I forget what the nominal diameter is s'posed to be. Could it be obstructed by refinishing or foreign material, or carbon. Are we talking about the regulator bleed-off, or the actual port in the barrel-to-gas-block?
Help me envision this, KO?

In the finest tradition of FALfiles gunsmithing I ran a paper clip (plenty of those around the office) through the gas block into the barrel. It appeared open and clean. The piston is in the trash and a new replacement is in the gas tube waiting its turn.
The fun part about working on this yesterday was the gun has the Williams receiver on it for additional problems. I got the BHO working on site and then the LS fell out of the gun. A friend was with me with his new Imbel kit and could not get it to cycle either. I took the piston from my STG58 (Century) and threw away his TAPCO piston, too small a diameter. That put him to working and me still wrestling.
This morning I got the LS to stay in for 30 rds. by putting Locktite on it. But I could not figure it out at the range and came home. Then I put in the new piston. Tomorrow back to the range.
It will be interesting to see if more of these cycling problems develop with the G1 kits.

If you got a mic.,check the LS hole dia.
.2975 is (I think)the nominal dia.
(that's the OD of jen's Locking Shoulders )
I had a LS from an IMBEL that was real loose like that but, had no mic to check the Dia. It's in my spares bag anyway.
Checked my gas system,she's squeaky clean,I did ,however give the gastube another turn in the gasblock.
When I got my kit,the Bleed holes were facing towards the top of the HG's(Maybe the last owner knew something I don't)and
yes, I know that's not how it's supposed to go but who am I to argue w/ the bundswher(sp) ;)
re-checked the Headspace also,seems I got some setback,looks like a new LS is in order.

Ted: My original in the trash piston measured exactly .429. I replaced it with one measuring about .433 (bad eyes and no machinist experience). I will see what it does today.
Newbie: If the LS comes loose I will check out the specs. Putting guns together with old parts may be the problem. I have no idea where that LS came from or its dimensions other than it measured .268. I will probably get a new one from Jen today if it comes loose again.
I still do not think it is the fault of the receiver at this point.

Bill I agree with you.
the LS I was referring to was from an IMBEL and it fit ok in the demilled chunk it came in.but it was loose in the IMBEL reciever I had.I didn't measure the OD of that particular LS (no Mic). but, I tried it in several recievers all w/ the same result.
spiralFabs Website lists a series of four different Locking Shoulders w/ different ODs.

Dan: I just got back from the range. After a few rounds I noticed the pins holding the ejector block were about 1/8 inch out of the receiver body. The tap back in with a screwdriver head. These pins are straight from Williams and presumably are new. They are of course going to fall out at some point.
I think they have serious problems in either making this receiver work or in quality control. I am reluctantly sending my Williams receiver back. I have no idea what the cure is or if it can be cured.

Should be fixable,sounds like the ends didn't open up enough when driven into their holes. they should peen themselves as they seat in the holes.
In all fairness, the Williams rec.is new and probably needs tweaking.
since it's guaranteed ,I'd not worry too much they'll make it right But,I see where you're coming from too.

Dan: I spoke to Jen earlier and she has new locking shoulders, somewhat oversize, which could be a cure for the LS problem.
I have dismantled the gun and will pull the receiver sometime this week when I get the time. I will probably throw it away or make a paper weight of it. Since we cut the shoulder on the barrel to fit the breeching washer that will probably be a throw away also. The warranty is to give a new one in the place of the old one. Like I need another?

Jen's Locking Shoulders are good items for sure, hope it works.
as far as the Bbl.you might be able to use it,try an IMBEL reciever....
The shoulder can be GENTLY peened to make up for overtiming if it's not too severe-I've swapped bbl and Rec.s several times w/o alot of problems.
I see your point about the Rec. but you should at least let Williams know so that it can be added to the list of problems to be ironed out by Wms.

I will probably keep the barrel over in the corner. I have another half dozen barrels to use not already commited to building. Now I will order an Entre'prise Type 1 to replace the Williams mess on the G1. Fortunately that was not my best barrel. I had picked the lesser one not knowing if I could match the finish with the receiver. Figured it to be some kind of Frankenfal at best. Then when I saw how well it looked I wished I had used the better barrel. Now I am grateful to not have made that mistake.
I have contacted Williams to let them know what a mess they have going. Since I do not plan on assembling a gun with one, at this time, I do not care a great deal whether or not it gets fixed.

Why not try sending it back and trying out Dwight's no questions asked refund policy? Since Williams Arms knew of the problems with the earlier run, maybe the later run will work better....
I hope mine is from the later run. :confused:
September 03, 2001, 22:17
good luck Bill.
Hope it all works out in the end.
I agree w/Law4fun;try Dwight's refund policy
September 03, 2001, 22:53
You know I want to take advantage of Dwight's refund policy. Right.
I am going to remove the receiver. This means a trip to sledgehammers, about 90 miles.
Then I am going to mail it back to Williams for 'another' on the strength of someone named 'Dwight's word that he will 'fix' it.
Then I am going back the 90 miles to sledgehammers and put on the 'new' version.
All that assumes that the barrel, that I cut to fit the 'old' receiver will fit the 'new' receiver.
Then we are all smiley faces :) :) :) right?
The $195 receiver is getting up their in price with a good Entre'prise that I know will work.
Also, the receiver appeared to be having problems with the feed ramps. It kept falling apart so fast that I never could resolve whether or not that was also a problem.
Just so everyone knows, this receiver came on Thursday last week and it was assembled at sledgehammer's on Friday. If 'Dwight' knew of the problems why keep shipping them? Just to see how many he could unload without replacing them with the 'new' version?
I think I will let 'Dwight' do his Beta tests on you guys for a while and just put this 'old' receiver either in the trash or in the corner.
