AR-15 – 6.5 Grendel

Description

AR-15 6.5 Grendel Custom Barrel

We make this AR-15 barrel in 6.5 Grendel. Take a look at the listed steel, twist, barrel length, gas-system and finish choices for this product.

Why 6.5 Grendel?

6.5 Grendel is a compact cartridge using 6.5mm bullets. It’s a different chambering from the .223/5.56 family associated with many AR-15 rifles.

The 6.5mm bullet diameter doesn’t mean the cartridge is the same as 6.5 Creedmoor. They’re different cartridges with different case dimensions, and their ammunition isn’t interchangeable.

Customize Your AR-15 Barrel

• Barrel material and twist: Check the options offered for this chambering.
• Length and muzzle: Choose among the listed lengths, crowns and muzzle finishes.
• Gas system: Review the gas-system lengths and optional gas tubes displayed for the selected barrel.
• Profile and gas block: Check the barrel profile, gas-block diameter and any optional fixed or adjustable gas blocks.
• Finish: Fluting, Cerakote and other finish choices depend on the configuration.
• Related components: Review any matching-bolt or customer-supplied part selections. Don’t assume every optional component is included.

Before You Order

• Confirm your rifle: This product is for an AR-15-pattern configuration chambered in 6.5 Grendel. Verify any related receiver, bolt and other component requirements.
• Check ammunition: Use the cartridge marked for the barrel’s chamber, not a different cartridge with a similar name.
• Review every selection: This is a made-to-order barrel. Check the options and separately selected components before checkout.

Barrel Options Explained

CM and SS: CM means chrome-moly steel, which needs corrosion protection. SS is stainless steel, which resists corrosion better but still needs normal maintenance. The rifling twist and steel combinations are listed with the product choices.

Twist rate: A marking such as 1:7 means one complete turn of the rifling every seven inches; it isn’t a barrel-length measurement.

Gas-system length: Pistol, carbine, mid-length, rifle and magnum name different nominal gas-system layouts. The specific options depend on the product.

What is a gas tube? In a conventional AR gas system, the gas block routes gas from the barrel through a small tube toward the action. The gas tube is separate from both the barrel and the block. Review the Add Gas Tube? option if you need one included where offered; its type corresponds to the gas-system layout.

Barrel profile: Light, SOCOM, HBAR and Bull are common names for outside barrel contours. The profile describes barrel thickness and material distribution, which affect the weight.

Gas block and mounting diameter: Measurements such as .750 and .875 identify the outside diameter of the barrel where a gas block fits, not the caliber. A block can be fixed or adjustable, depending on the product choices. If you already have your own suitable gas block, look for the None selection where offered. Diameter alone doesn’t guarantee compatibility with the entire system.

Muzzle treatments: A target crown is an unthreaded muzzle finish. Threaded muzzles have a defined thread size and pitch. Magna Port is a muzzle-porting style, while Gill Cut refers to a specialty cut pattern. Ask us to confirm which finishes apply to the barrel you are considering.

Q / SIG taper (optional, no extra taper charge): Standard 5/8×24 muzzle threads typically have a flat, 90-degree shoulder behind them. The Q / SIG option uses those same threads with a 25-degree angled shoulder instead. Certain Q- and SIG-style muzzle devices and suppressor mounts are made to seat against this taper, giving the mount its intended contact surface. Why choose it? It is a fitment choice: select 5/8×24 Threads + Q/SIG Taper if your specific mount calls for a 25-degree taper, or choose standard 5/8×24 threads if it calls for a flat shoulder. The taper does not change the thread size or automatically improve accuracy. There is no extra taper charge beyond any existing threading cost. Check your mount specifications or ask Deadshot if you are unsure.

Barrel extension: The steel part at the rear of the barrel contains the locking surfaces for the bolt. It’s different from the gas block.

Fluting and finishes: Fluting refers to grooves cut into the exterior of the barrel. Cerakote and other finishes affect appearance and surface protection.
