What’s up everyone new member here. I have a Trojan Firearms (Trident AR10 .308) and I been having issues with the gun firing and ejecting properly. I can never get it to fire smoothly without it jamming, miss firing, etc. I started with the adjustable SA gas block then switched to the SA fixed gas block. That didn’t work so I am now using the Rifle Speed adjustable gas block and it’s still not running smooth with occasional jamming and miss fires. It came with a 3.4 oz buffer and I also added weight to it where it was around 5 oz but that didn’t fix the issues either. What else should I try to configure to fix this issue. Thanks. |

Check to confirm that the gas block is properly aligned over the gas port, as any obstruction here can cause a fail to eject, and often times fail to pick up the next live round off the magazine. Next try installing just the bolt carrier (No bolt, cam pin, or firing pin) into the upper receiver, and see if it goes freely forward and back inside the upper receiver with no binding, as it should free float. For process of elimination, start with a thorough cleaning of which includes using a chamber brush to get any possible debris removed from the chamber. I like to then swab things out with denatured alcohol, which will remove any solvent and/or oil and leave it dry when the alcohol evaporates. Then lube the 7 bolt lugs so that each lug is good and wet with quality lubricant, my personal preference is Slip2000 Extreme Weapons Lube "EWL", as this will help eliminate that it isn't friction on the lugs as the bolt carrier assembly unlocks to go the rear. I would suggest trying a one shot test to determine if it will lock back on an empty magazine. This means load one round into the magazine, and insert it into the magazine well with a solid push followed by a tug down on the magazine to confirm it is locked into the magazine well. Then manually cycle the charging handle to the rear until your fingers come off, and let the buffer spring (action spring) push the bolt carrier assembly forward, where it should strip a round off the magazine, push the live round up the feed ramps and into the chamber, and the bolt should fully rotate counter-clockwise and lock into battery. Then fire the gun, at which time the bolt should rotate clockwise and unlock from battery, the bolt carrier should go rearward at which time it should extract the empty casing from the chamber, the bolt carrier should continue to the rear to fully eject the empty casing and at the same time recock the hammer, and then the bolt carrier assembly should lock back on the bolt catch that is pushed upward by the follower of the magazine. Also I see no mention of ammunition. Have you tried different ammunition that is factory new from a quality American made manufacturer, and if so were there any difference in performance?

Everything Sully said. Welcome to Arfcom. I don’t know anything about your brand, but I had to fight through an over 100 rounds with a DPMS Lr308. Many stoppages of all sort. Just kept it lubed cause I couldn’t find a problem, other than 2-5 various stoppages per mag. Around 100 rounds it went down to running 99%, another couple hundred and it just ran. Part of that was on me, I wasn’t aware S African surplus ammo caused problems in that brand. |
If life was easy nobody would quit.

Rifle length gas tube on a AR15 vs AR10 is different, but most don’t realize it and tons of companies don’t use the right length, they just use the AR15 rifle length which is slightly shorter. So the gas tube doesn’t sit as far into the gas key as it should. Shockingly, Anderson makes the correct length AR10 tube and they’re great, never had an issue from one. |
