works great

by skiff, Verified Owner from OH, United States Written on February 10, 2024
Great addition that opens up tons of options sure you can have more uppers but then you need more bolt carriers hopefully quality ones. Optics and other parts. This seems cheaper can use same high quality optic bcg and upper.

Quick change is good

by Artful, from AZ, United States Written on February 23, 2022
So now with one registered receiver I can choose to shoot multiple calibers by just carrying extra barrels. And a quick twist off and another on and can go from 5.56 to 300 Blackout to 350 Legend. Same magazine and BCG

Dolos Lock Coller

by Guy Cowden, Verified Owner from NM, United States Written on March 20, 2018
Not much to say about this product works good with the dolos as it is designed for. Packing was good and protected the product no scratches or dents. Only down side is the price I wish it was around half the price. If it was only $50 I would buy more and have the option of changing barrel lengths instead of just using it as a take down pistol. Love the idea just needs to be a little less expensive.
Pros:
  • easy to use
  • easy to indstall
  • Take down ability
  • Helps with cleaning
Cons:
  • price
Best Used for:
  • Take Down Firearms
  • Compat storing
Would recommend: Yes

Pantheon Arms AR15 lock collar.

by usafvet80, Verified Owner from AZ, United States Written on August 9, 2017
I have a few of these. The Pantheon Dolos makes it so I can quickly change barrels on ma AR15 so I can use the caliber that fits my situation as well as my AR15 fitting easily in my day pack/ Gobag. The whole system is easy to install and once finished with it you can change barrels in 30 seconds literally. If I get stuck in town and needed my AR15 to get home because society broke down, it would be just a matter of grabbing my Gobag and no-one would know I had my rifle.

Dolos lock collar

by Stan, Verified Owner from SC, United States Written on July 28, 2017
One of the hardest things to find for purchase. Supposed to be also available at Cooper Custom. Haven't found it anywhere else for 4 months. A completely necessary item if you are going to use your own forearm, YHM or other compatible unit. Makes the system what it should be: an interchangeable barrel system.
Pros:
  • critical piece
Cons:
  • hard to find
Best Used for:
  • Dolos quick change system
Would recommend: Yes
