Cut Safeties and Gas Cylinder Lock Questions

[ZBeast]

Are the cut safeties safe for use? Is this an acceptable modification? Also, I have a problem with a gas cylinder lock. It looks like it has to make about 3 more turns to seat against the gas cylinder. It has got quite tight and I am not sure if I need to wrench it on or chase the barrel threads(they look good and sharp) The lock works on other barrels. All suggestions are welcome and appreciated. ZB.

I've used many cut safeties(and still do) in the past and they still work as far as a safety,they just allow them to be put on "safe" while hammer is not cocked.

On a historical note, these safeties are NOT really broken, they were MODIFIED by GI's in the field as it was found that by removing the tip the safety would engage and disengage quietly. So if you find your trigger group has a tip broken off....leave it! The last user was a combat soldier!!

Ok, safeties are safe. The gas cylinder thing is next. I have assembled 4 rifles to date and this is the first one to have given me grief.I tap the gas cylinder on till it hits the front handguard. Then screw the lock on where it then gets tight about three turns from the gas cylinder. If I try the lock screw it pulls the cylinder forward and the front handguard gets loose. What is the die size/ thread cut for the barrel thread ? Maybe just a good chase? The lock will screw up to the splines on all my other barrels. The problem barrel only goes to the end of the threaded cuts. Thanks again folks. ZB

This sounds about right,the threads end where they are supposed to,and is probably gtg.The handguard may be a bit short as some are,and there should be some play between them.

A broken safety is half as safe as they were designed. The hammer block feature will now not work.

The trigger can not be pulled. Hence safety works..

Would probably cost dearly in a liability lawsuit.

This is exactly why I have to have people sign waivers and such OR fix their safety when broken ones come in. The rifle was designed to have two features of the safety prevent the rifle from firing. I don't think two features are needed but two they had. If you sell a car with a shoulder and lap restraint seat belt being the factory default and you have now removed the shoulder restraint portion, you might have a tough time keeping your house should an accident happen to the new buyer and they are hurt more because of their upper torso not being restrained.

Don't get me wrong, just stating what will happen with 99% of people when money is or could be involved. It's never your fault, it's somebody else's.

HEY! HEY! Just remember. I'm an old geezer with my opinions, and history would say some soldiers intentionally snapped the end off.
