Notes from Ally Munitions
-
These are the exact same barrels used in our MUTT 1 rifles, which earned a great reputation for accuracy and consistency.
-
We’re now moving toward producing our own barrels for future builds, but we stand by these 100%.
-
Each barrel is visually inspected by us before shipping. If there's a cosmetic issue, we handle it on our end—no questions asked.
-
While this item doesn’t include our in-house accuracy guarantee, Ballistic Advantage’s 1 MOA guarantee still applies.
-
If you experience any issues, reach out to us—we’ll help guide you in the right direction.
Performance and Compatibility
-
In our testing, these barrels handled all factory ammo options with ease.
-
Excellent thermal management—fluting cuts cooldown time nearly in half compared to the non-fluted variant.
-
Weight savings are noticeable, especially with the deep flutes.
-
Pairs extremely well with the CMC BCGs we offer—this is the exact combo we ran in all MUTT 1 uppers.
-
We’ve consistently seen perfect headspacing between these barrels and CMC BCGs, which is critical for both safety and performance.
-
The advantage of pairing the CMC BCG with the included CMC gas tube is that it pretty much guarantees gas key-to-gas tube compatibility, reducing setup headaches and improving gas efficiency.
-
One thing we always recommend—match your gas tube and gas key brands. It’s a small thing that makes a big difference in achieving a reliable, efficient gas system.
Our Go-To Build Advice
For best results, we recommend pairing with:
-
Flat wire buffer spring
-
H3 or H4 buffer (preferably both for tuning)
-
Superlative Arms adjustable gas block (also available through us)
This combo has proven itself time and again—especially with lighter projectiles. This barrel makes for an excelent more compact varmint rig. With the 16" barrel you can still achieve muzzle velocities of 3000 fps plus, witht he 65-70 gr projectiles.
