Tested my .050 gas bushing in my mini 14.

Sounds like you are due for a new gas block. I punched the gas port on my barrel out to .062 that way it would cycle the classic mini14 pet load, which is about a start load of H322 and put an adjustable gas block on there for use with normal full power ammo.

replace the gas block screws when you remove your gas block the first time and usually they good after that. I used the .035 (If i remember correctly, it was the smallest one) and ran em hot.

Oh I thought you meant the holes were stripped.

I bet with hot ammo, like a max charge of leverevolution or 760 a .025 or .030 gas port would cycle the gun.

Gotta have new screws! Rather than launch into an explanation of what screws to look for at the hardware store... just follow this link to Cogburn Arsenal...

FYI in case folks want to know, the gas block screws are not a common size you are likely to find at most stores. Size is 8-36 UNF x 3/8 Socket Head Cap Screws. Uses a 9/64 Allen key.

A little update. I ordered new gas block screws and a Wheeler fat wrench, I also found my .045 bushing in. I put it in. And just hand tightened the block for now. I watched some videos of the fat wrench being used. There is no way my harbor fright ratchet one is correct.

I think somebody said it earlier in the thread, but at least in my experience, even torque is more important than correct torque on a mini's gas block.

I did mine with an Allen wrench, and then re-did it when I change jobs and they actually had a quarter inch drive torque wrench....the deflection style one, not the clicker..... I didn't see any real changing accuracy.

The .045 bushing worked great. The brass flew about 8 feet. The loads with the same powder weight. Kept the brass at 2-3:00. View attachment 1142702Question, after i get them torqued even. Should i use loc-tite?

I wouldn't, never experienced any of mine coming loose.

In addition to the the torque being even, the gap between the plates should also be equal all around.
