Which would be better for a dissipator setup, and why? 1. Carbine Length gas system. 2. Mid Length gas system. 3. Full rifle barrel cut and recrowned to 16" I don't care if I have to lose the FSB and run a tube handguard with a flip front sight. I just got the M4gery built, now it's time for receiver #2.  I want a dizzy REAL BAD. I just don't know what setup is going to be the best for me. |

Ok, if I understand this right I can take a 20" barrel, and have it shortened and threaded for a dissipator and not suffer any reliability issues due to the location of the gas port. I am hoping so, because that is the plan. I can pickup a barrel and send it to ADCO to be refinished. By the time January is over my wife may kill me. I am starting to have more $$ in guns then she does in jewelry.

| Either with the a shortened 20" barrel, or a carbine gas system, or mid-length gas system, you are still using a 16" barrel, and thus, bullet velocity will still be that of a 16" barrel, which is about 150-200 FPS less than a 20" barrel. I am also looking at a dissy and decided to use a barrel with the carbine gas system, because it is tried and true. |
Here. Didn't do anything to the gas port. I did have a problem at first and cut 1&1/2 coils off the buffer spring but now that I think back I think the culprit was a brand new, too tight McFarland gas ring. |
