Most Helpful Positive Review Great tool
Works flawless, buy it with the hand guard combo. It cost less to get the combo because it takes a special hand guard to go on the dolos take down. I would recommend this to anyone who whats to remove and reinstall barrel witbout loss of accuracy.
Most Helpful Negative Review Neat idea but needs further refinement
I had 2 of these installed on AR15 pistols with Law Tactical folding adapters. This produced a neat, very small, easily packable, firearm. Unfortunately, I had trouble with the the threaded ring nut that fastens the receiver mount loosening periodically. This could probably be fixed with high heat, ...

Review of dolos takedown system build

by Steve, Verified Owner from OH, United States Written on September 21, 2025
Product works as intended. The assembly was very easy. I found out about the barrel retainer after the order. Kinda wish that was a recommended product with purchase. I ordered after the assembly so i guess i will find out how much it improves the assembly in another week.
Pros:
  • Makes the gun break down small for a backpack at a cheaper price than other systems
Cons:
  • None
Would recommend: Yes

Quick Take-Rifle Parts

by John Farill, Verified Owner from TN, United States Written on August 17, 2024
I just recently purchased the Dolo system. I love it. I was originally looking at the cry havoc system. However, after a lot of study and contemplation, I find this to be a better system that’s easier to initiate and disassemble. In addition, it is substantially cheaper than the aforementioned system. I look forward to purchasing several more of these for future bills. Buy with confidence.

Works well

by Jake, from TX, United States Written on November 20, 2023
This is my second Dolos. Works well and as advertised. After 5 years and thousands of rounds, no complaints or malfunctions. Much cheaper than other take down options.
Pros:
  • Easy to use & Light Weight
Cons:
  • Narrow variety of compatible forends.
Best Used for:
  • Stow-able rifle/pistol applications
Would recommend: Yes

Dolos Kit Great for a compact AR.

by Jerry Idol, from NC, United States Written on October 8, 2021
I bought just the Dolos kit minus the handguard as I already had a handguard that worked perfectly with the Dolos system. It was easy to install and easy to time. I lubricated the working parts and it fits perfectly in my small tote bag. It is a great addition to any Ar build.
Pros:
  • Makes an AR small and compact
Cons:
  • No Cons All good
Best Used for:
  • Conceal and Carry / Home Defense
Would recommend: Yes

Dolos Takedown

by JoH, from SC, United States Written on November 7, 2020
Very nice takedown system...very simple to install...my only hang up is...this will require special handguards, and only fits on Mil Spec upper recievers due to the anti rotation tabs. I am looking to have 556/300/350 barrel swap system using the same bcg...so this was entirely necessary.

Dolos system

by Randall, from OH, United States Written on August 15, 2020
Like it however after I purchased it I went back on the site and seen I could’ve also got the handguard for only $20 more, I wish I would have been up sold I would have purchased the full system with the hand guard. I eventually will but now I have to wait to install it. Overall very excited to get this added to my AR.

Dolos QD takedown

by Mac, Verified Owner from IN, United States Written on August 7, 2020
Installation was fairly simple and easy. Is a great upgrade for mobility and concealment for get home or bug out bags. Easy to use and great space saver for smaller bags that are more discreet and covert.

Great product.

by Manko, Verified Owner from NM, United States Written on May 24, 2018
This is my second kit I bought and I love it! It is easy to install. This kit makes barrel swaps extremely easy. The rachet system it uses to lock the barrel is solid and hold zero. I have broke down my rifle hundreds of times and still has the same zero.
Pros:
  • Quality product, easy install,
Cons:
  • None
Best Used for:
  • Good add on if want to shoot multiple calabers from a single rifle set up like .223, .556 and 300 blackout with out swapping the bolt just the barrel.
Would recommend: Yes

Easy barrel removal

by Goldendad, from PA, United States Written on May 1, 2018
This is a well made product. A bit pricey but if removing the barrel is something you need to do, this is your product. It could be cheaper in the long run than building a complete upper to change calibers. Be aware, you must buy a compatible hand guard, not all hand guards fit.
Pros:
  • Well made, ease of assembly, convenience
Cons:
  • None
Would recommend: Yes
