Davidson Defense Power Grid 4.5-inch 1:10 9MM AR-9 Freefloat M-Lok Handguard Pistol Full Build Kit, SBR Ready

Davidson Defense Power Grid 4.5 Inch 9MM AR-9 Freefloat M-Lok Handguard Pistol Full Build Kit SBR Ready

The Davidson Defense Power Grid delivers a complete 9MM AR-9 pistol platform in an SBR ready configuration. Featuring a 4.5 inch medium profile barrel constructed from 4150 Chrome Moly Vanadium steel with nitride finish, this kit balances compact dimensions with reliable 9MM performance. The 1 in 10 twist rate stabilizes common 9MM bullet weights while 1/2x36 threads accommodate the included 9MM A2 birdcage flash hider. A 4 inch M-Lok freefloat handguard crafted from black aluminum provides a lightweight and modular platform for accessory mounting. The upper receiver is machined from 7075-T6 aluminum with anodized finish for corrosion resistance and strength. The kit includes a mil-spec AR-15 lower parts kit for complete lower receiver assembly. A 6 position buffer tube and nitride bolt carrier group manufactured from 8620 alloy steel complete the package. This comprehensive build kit delivers coordinated components for assembling a reliable and customizable 9MM AR-9 pistol configuration.

• Builds requiring both upper and complete lower parts

SBR Ready Configuration

Ships without a brace and is intended for customers selecting their own final setup based on configuration preferences and applicable laws. This approach provides flexibility for builders who may choose to add a brace, plan future SBR registration, or configure the pistol according to their specific requirements. Follow applicable laws and do not install a stock unless compliant with regulations.

Complete Lower Parts Kit

The mil-spec AR-15 lower parts kit includes trigger group, safety selector, magazine catch, bolt catch and other components needed to complete a stripped lower receiver. This comprehensive kit eliminates sourcing individual lower parts from multiple suppliers. Mil-spec dimensions ensure compatibility with standard AR-15 lower receivers. The included 6 position buffer tube provides adjustability for future brace or stock installation based on configuration decisions.

8620 Alloy Steel BCG

The nitride bolt carrier group manufactured from 8620 alloy steel provides the strength needed to handle blowback operating forces in 9MM AR platforms. This material choice offers superior toughness compared to standard carbon steels while the nitride coating creates a hard, low friction surface. The coating reduces wear, simplifies cleaning and allows operation with less lubrication. 8620 alloy construction ensures the BCG withstands high round count use common in 9MM training and competition.

Freefloat M-Lok Handguard

The 4 inch freefloat handguard isolates the barrel from external contact, supporting accuracy by preventing shifts in point of impact from grip pressure or mounted accessories. M-Lok slots provide direct mounting for lights, grips and other devices without additional rail sections. Black aluminum construction delivers strength while keeping weight minimal. The freefloat design also aids heat dissipation during sustained fire while the compact length maintains practical dimensions.
