One thing I really like about LIMA6 is its compatibility with more common AR parts than other belt fed AR upper out there. I actually consider the DI system of the LIMA6 superior to the other piston operated system. It's overall lighter, less moving parts, and more compact. LIMA6 would function much that of M249 para or MGA SAW K, more suited for mobility and CQC then a fix position fire support. Not being used as a fix position fire support, the need for QC barrel is diminished. However, a QCB still has a purpose, the ability to switch caliber without needing to take the upper apart. It is where the LIMA6's AR compatibility comes in handy, there are existing AR QCB system out there that can be easily adopted to LIMA 6. There are currently at least three companies that has AR QCB systems: Pantheon Dolos, Cry Havoc,LEO Takedown Out of the three, believe the Dolos has been around the longest, US Air Force is using Cry Havoc system for their air crew survival rifle kit, and LEO Takedown seems to be the newest. All three system uses the standard AR receiver's barrel nut thread with its adaptor. Once the adaptor is installed, it is simple just twist, clamp on/off between the barrels. QCB for AR only benefit is compact storage. However, for LIMA6 it provides the option of quick caliber change, barrel length swap, since it is not practical to switch upper receiver of LIMA six. I had previous experience with the Dolos system, so I gone ahead and tried out using it for the LIMA. Quick modification of the Dolos' adaptor to remove its antirotation taps, installing it was straight forward. With its barrel bushing, the piece that holds the barrel and locks into the adaptor, I now have QCB LIMA6. I have both 556 and 300BO barrels, swapping between the 2 takes less than a min. If anyone is thinking about adding QCB, may want to take a look this option. |

Do you have any pics of the modification needed? I heard Harvey say that is what is needed, but I didn't want to spend the money and risk messing it up. What do these tabs do and does removing them have any potential to negatively affect the L6? Ive been wanting this for the caliber change possibilities mostly |

Pantheon Arms (the maker of the DOLOS) just finished a version of their product to work with the L6 (without modification), and it should be hitting shelves soon. We will be testing it shortly. Also, there is a member here working on a true drop-in QD barrel system: https://www.ar15.com/forums/Armory/QD-Barrel-System-for-Lima-Six-Upper/65-562628/ |
