Davidson Defense High Tide 16.5-inch Mid-Gas 1:7 .223 Wylde AR-15 M-Lok Handguard Rifle Full Build Kit

High Tide 16.5-inch Mid-Gas 1:7 .223 Wylde AR-15 M-Lok Handguard Rifle Full Build Kit

This is a complete AR-15 rifle kit built around a 16.5-inch nitride 4150 CrMoV barrel chambered in .223 Wylde. The kit includes everything except the lower receiver, with a mid-length gas system, freefloat M-Lok handguard, and mil-spec components throughout. The 1:7 twist rate stabilizes a wide range of bullet weights from 55 grains all the way up to 77 grains, making this a versatile platform for both target shooting and defensive applications.

• Shooters needing a complete kit without sourcing individual components

Versatile .223 Wylde Chambering

The .223 Wylde chamber accepts both 5.56 NATO and .223 Remington ammunition, giving you flexibility at the range. The 1:7 twist rate is fast enough to stabilize heavier bullets like 77-grain match rounds while still handling lighter 55-grain loads reliably. This combination makes the High Tide kit equally at home punching paper at distance or maintaining control in dynamic shooting scenarios.

Mid-Length Gas System Design

Mid-length gas systems strike a balance between the softer recoil impulse of rifle-length systems and the faster cycling of carbine-length designs. Paired with the micro low-profile gas block, this setup reduces felt recoil and brass ejection distance compared to carbine-length alternatives. The stainless steel gas tube resists corrosion and extends component life.

Freefloat Handguard with M-Lok Modularity

The 15-inch Avalon handguard floats free from the barrel, eliminating contact that can affect accuracy. The M-Lok attachment system lets you add accessories where you need them without tools. Slant port cutouts reduce weight while maintaining structural rigidity.
