The Battle Arms Development Xiphos 9mm Luger – 30+1, 8.50" Black Barrel, M-LOK Handguard, Combat Gray Aluminum Receiver, Black Synthetic Adjustable Stock, Adjustable Black Grip (Model XIPHOS004, UPC 810033782794) is a premium next-generation pistol caliber carbine built from the ground up for defense, duty, and competition. Purpose-built around Battle Arms’ billet BAD-GS receiver and lightweight 9mm blowback system, the Xiphos delivers soft recoil, fast handling, and AR-style ergonomics in a compact 9mm package.
If you’re looking for a feature-rich 9mm AR-style platform with modern furniture, an 8.5" barrel, and 30+1 capacity, the Xiphos XIPHOS004 is built to run hard and shoot flat.
Purpose-Built 9mm Pistol Caliber Platform
Unlike simple conversions, the Xiphos series is designed as a dedicated 9mm blowback firearm from day one:
Caliber: 9mm Luger
Capacity: 30+1 (ships with 30- or 33-round magazine depending on configuration and market)
Operating System: Straight blowback, tuned for reliability and controllability
Accepts Glock-pattern 9mm magazines, giving you widely available, easy-to-source mags for the platform
The result is a compact 9mm carbine that feels natural to any AR-15 shooter but runs inexpensive, easy-to-control 9mm ammunition.
8.5" Black Nitride 4150 CMV Barrel – Compact & Accurate
At the heart of the Xiphos is an 8–8.5" lightweight 4150 chrome-moly vanadium barrel with a black nitride finish:
Length: 8.0–8.5" – an ideal sweet spot for 9mm velocity, balance, and maneuverability
Material: 4150 CM/CMV steel for durability and long barrel life
Finish: Black nitride for excellent corrosion resistance and easy cleaning
Twist Rate: 1:10" optimized for a broad range of 9mm bullet weights
Threaded muzzle (typically 1/2x36 TPI) with an A2-style flash hider, allowing you to add suppressors or other muzzle devices where legal
That combination of premium barrel steel, nitride finish, and compact length makes the Xiphos at home in tight interiors, vehicles, or fast-paced competitive stages.
Combat Gray Billet Aluminum Receiver & M-LOK Free-Float Handguard
The BAD-GS billet 7075-T6 aluminum receiver set is the structural heart of the Xiphos series:
Receiver: Precision-machined 7075-T6 billet aluminum
Finish: BATTLEARMS® Combat Gray for a modern, durable, low-glare appearance
Handguard: Free-float WORKHORSE® M-LOK handguard (approx. 6.7"–9.5" depending on version) with M-LOK slots at 3, 6, and 9 o’clock
Top Rail: Full-length Picatinny rail at 12 o’clock with Battle Arms’ signature notch that perfectly matches the upper receiver for a seamless look
The free-float M-LOK system lets you mount lights, lasers, vertical grips, and sling hardware without adding excess weight or interfering with barrel harmonics.
Lightweight, Soft-Shooting 9mm Buffer System
Battle Arms equips each Xiphos with its patented 9mm buffer system, engineered specifically for the platform:
Reduces felt recoil compared to typical blowback 9mm AR setups
Minimizes bolt speed and wear, increasing long-term durability
Helps keep the gun flat for faster follow-up shots in competition or defensive use
Combined with the 9mm cartridge’s inherently mild recoil, this buffer system makes the Xiphos extremely controllable for shooters of all experience levels.
Enhanced Controls & Ambidextrous Charging Handle
The Xiphos is loaded with upgraded controls that enhance usability out of the box:
RACK™ ambidextrous charging handle with monolithic handle and side-sliding latch, built to withstand hard use
Extended magazine release for faster reloads
Enhanced bolt catch and one-piece magazine catch
Enhanced takedown and pivot pins for tool-less breakdown and maintenance
Enhanced single-side safety for positive on/off engagement
All of this makes the Xiphos feel more like a fully custom build than a standard factory gun.
Adjustable Black Synthetic Stock & Adjustable Grip
This configuration of the Xiphos features black synthetic furniture focused on ergonomics and adaptability:
Adjustable black synthetic stock – lets you fine-tune length of pull for different shooters, gear, and shooting positions
User-adjustable three-position pistol grip so you can set the grip angle that feels best for defensive, patrol, or competition work
Textured grip surfaces for secure control in wet or gloved conditions
These features make it easy to fit the gun to your body and shooting style, improving comfort and speed on target.
Optics-Ready, AR-Style Interface
The full-length top Picatinny rail makes the Xiphos fully optics-ready:
Mount red dots, prism scopes, LPVOs, or irons exactly where you want them
AR-15 style controls and layout ensure instant familiarity for anyone used to the AR platform
Ideal for close-to-mid-range shooting in home defense, PCC competition, or training roles
With no fixed sights in the way, you’re free to choose the exact sighting solution that matches your mission.
Compact, Lightweight & Ready for Work
Despite its full feature set, the Xiphos remains light and maneuverable:
Weight: around 5.5 lbs, unloaded
Overall length: approximately 23.25" collapsed to 26" extended, depending on stock position
That makes it easy to manage in vehicles, hallways, and tight spaces, while still offering a stable platform for shoulder-fired accuracy.
Ideal Uses – Defense, Duty, Training & PCC Competition
The Battle Arms Development Xiphos 9mm XIPHOS004 is a flexible platform that excels in multiple roles:
Home & personal defense: 9mm chambering, AR controls, and low recoil make it intuitive and fast
Law enforcement or security duty: rugged billet receiver, enhanced controls, and Glock-mag compatibility
Pistol caliber carbine competition: soft recoil, fast handling, and M-LOK rail space for match-ready accessories
Training & range work: cheaper 9mm ammo lets you train more without changing your manual of arms
If you want a premium 9mm AR-style carbine that’s built like a custom gun but ready straight from the box, the Xiphos is a standout option.
