Works great for my AR-9
Written on Feb 18, 2019
I got this for my AR-9 pistol build and can't be happier. I was able to break it down and into a 16" wide hard case, my Go-case. The problem with the AR-9 is that it doesn't have the gas block to keep the collar from moving from the base of the barrel to the muzzle device. I had to buy a "barrel stop" to make the install faster and now my barrel only slides up to about an inch.
I had to adjust the pin that ratchets the handguard. The unit that I received, the pin was still protruding that it's still catching on to the teeth of the base. I was able to adjust the pin by manipulating the screw in the pull-down release.
My pistol remained zero after removal and install of the Dolos. I'm happy I got this. I may get this for my AR-15 pistol build as well.
