Dead Air DA458 Xeno Adapter Legacy 4140 HT Alloy Steel Black Nitride$111.25
Availability: In Stock
The Dead Air DA457 Xeno Adapter is a precision mounting interface designed for shooters who demand repeatability without adding weight or length to their rifle. This P-series adapter bridges a Xeno muzzle device to industry-standard 1-3/8-24 (HUB) threaded suppressors, making it a versatile choice for builders and precision rifle owners working with multiple silencer options. Built from nitrided 4140 steel, the DA457 resists corrosion and thread galling—a real-world advantage when you're running suppressed for extended strings without disassembly.
The Xeno system's design philosophy centers on a shorter footprint and shallow muzzle device seating that minimizes baffle erosion, potentially extending suppressor service life while maintaining sound performance. Unlike deeper-seated mounting systems, the Xeno's positioning reduces focused heat and carbon buildup on internal baffles. The left-hand threaded connection between adapter and muzzle device prevents unintended loosening during removal, and you can verify torque integrity during installation—a handy feature for suppressed rifles that stay mounted through hundreds of rounds.
Tooling accessibility is built in throughout the adapter, with 1-1/8" socket and 1.5" hook spanner compatible surfaces. This means you can torque the mount even with a suppressor fully installed, critical for shooters who don't frequently strip their suppressors for cleaning. The nitrided 4140 finish also makes carbon and copper fouling easier to clean without risk of thread damage—a practical benefit when you're maintaining a suppressed precision rig.
| Weight | 1.60 oz |
| Overall Length | 1.125" |
| Material & Finish | 4140 HT QPQ Black Nitride |
| Suppressor Threads | 1-3/8-24 (HUB) |
| Muzzle Device Threads | Left-hand threaded |
| Tool Features | 1-1/8" socket and 1.5" hook spanner compatible |
The DA457 uses industry-standard 1-3/8-24 (HUB) threads, making it compatible with a wide range of suppressor models across the market that feature this common thread pattern. Confirm your suppressor's thread specs before purchase.
Yes. The adapter's tool-accessible surfaces—compatible with 1-1/8" socket and 1.5" hook spanner—remain accessible even with a fully installed suppressor, allowing you to verify or adjust torque without removal.
Left-hand threading on the muzzle device interface prevents the adapter from unthreading from your suppressor during removal. It also lets you confirm the mount is still tight when you reinstall it on your firearm.
The Xeno's shallow seating of the muzzle device minimizes focused erosion on the suppressor's baffles compared to deeper-seated systems, potentially extending suppressor lifespan while maintaining sound performance.
