Gas Plug hole size on Socom 16

Hello all,

I bought a pre-owned Socom 16 and have a question about the hole size on my gas plug.

I bought the Sadlak Industries 2pcs drill set to clean the gas system and found that the gas plug hole on my rifle is too small for the P. Can someone direct me to the correct size for that?

Unrelated kinda but also noticed the brake when I put it on has the ring at 9 o'clock spot. I would have to turn it back to 6 and loosen it to install gas plug. Is that normal or should I put shims on before installing the brake to get correct 5 o'clock? Are Shims put on barrel? Seems different set up to the longer ver of this rifle.

First time owner and excited to say the least. Watched Tony's video's and took good notes. I think I have all the other goodies needed to maintain the rifle.

Thank you in advance for the help!

The Sadlak 2 piece cleaning drill set is for the gas piston only.
the gas piston has two different diameters.
The "P" bit for the piston is .323".
The Sadlak gas plug cleaning drill bits come in two sizes.
The "O" bit is .316" and is what it sounds like you need.
And a "V" bit for the SEI Socom gas plug. Which has a .377" bit.

Your gas cylinder lock will need to be shimmed to time it right.

This picture shows where the shims get placed.

Hope this helps.
Glenn

I ran into the same issue with the gas piston on my 2012 Scout.

The smaller end, I'll call it the tail, has a different internal diameter than the drill bit I purchased, based on info found here.

The bit was just slightly too big.

I asked awhile back if the Scout gas piston was different internally but no one could come up with an answer.

I just pulled out my drill bit set and found one that would work, just don't remember which one it was.

Glad to be able to help.

Also Welcome to the Forum.
Sorry, I forgot to mention that in my first response.
As a Socom 16 owner I would love to see some pictures of your rifle and a range report.
Tony's videos are a wealth of information. We are truly bless to have him here.
If you have any other questions, please ask. There are plenty of people here willing to help.

Thanks,
Glenn

I just ordered a Aimpoint pro and a low profile ring along with shims before heading out to the range. Just like having all my bases covered first.

I bought a box of Federal Surplus 149 gr FMJ to go shoot the rifle to start. I plan on making sure my irons are on then adding the Aimpoint to finish off the day. We have a local range that goes out to 500 yards to test but will stick to the 300 and under targets. I found with my Colt AR/aimpoint 300 was about the limit of these old eyes.

Thanks for the links Rabbitone

Picture of my Rifle and my first day at the range with it. Untapped are 10 shot groups with taped ones being adjustments. Time and weather limited me to the initial 25 yard starting point. Red target was fired at a good rate just to test function i.e. Jams and failure to feed etc.
