I have a CETME that a friend asked me to take a look at. Looking for some help on this issue. When I pull the charging handle back, something is causing the b/c/ch assembly to majorly stick about 1.5" forward of the hold-open cutout. A firm tap on the muzzle will send the bolt flying back forward. About 1 in 10 times the bolt will just pull back normally... I can't figure out the problem. Is it a crooked receiver? Bent guide rod? Advise! |

John, sorry I ain't got any CETME. I can tell you about Garands, M14, M16, and .30 Carbine, but, damn, no CETME. I hate to see a shooting brother twisting in the wind. Try: CETME RIFLE MANUAL or: CETME FOR DUMMIES or better still: CETME RIFLE FORUM |

First I'd remove the bolt carrier and see if the charging handle is what's hanging up. The slot the charging handle rides in may have burrs where it was cut. Mine did and was much of my trouble. After you check and fix any problems with the charging handle, then put the carrier back in and check for tightness. Drop the bolt and carrier in and use a stick or something to push it down. There will be resistance when the bolt locks into the barrel but it shouldn't be too hard. Lastly check the captured spring in the buttstock and make sure it has no bends, burrs, etc. If you have access to another CETME, swap parts and see if there is a difference. When I first bought mine, I almost needed to kickstart it like a bike to cock it. After finding many small things wrong and fixing them, it works great now. Things I found wrong on mine (that I remember) are: 1. Burrs in the charging handle slot which made it bind up. 2. The weld holding the rod that holds the spring in the buttstock was broke. 3. The ejector in the trigger group was too short and couldn't reach the shell casing. Mine is a stainless receiver which is thicker than the stamped version. I added weld to the top of the ejector, then reshaped to fix that problem. 4. With all I did, it was still pretty tight to cock so I manually cocked it hundreds of times to break it in. Drove my wife nuts!!!!! LOL  I did all that before I fired the first shot out of it and it ran great. Be sure to clean the chamber grooves out with a brush also. They help the shell extraction by floating the just fired shell casing. Hope these ideas help. |

I found the problem. The ejector in the trigger group is sometimes slipping sideways out of the slot in the bottom of the bolt and causing the gun to bind. Anyone know why it would be slipping out of the slot? I can't find anything that's supposed to be tightened/etc., so I don't know how to prevent it from slipping sideways and binding the bolt. Some help! |
