M4A2 looks with SPR accuracy.
This AR-15 kit features classic M4 carbine furniture and a precision 416R stainless barrel with a heavier profile and mid-length gas for maximum accuracy and more reliable cycling.
The A2-style split handguard offers a lightweight and low profile, while the A2 front sight base pairs easily with any flip-up or fixed rear iron sight of your choice.
Pair this rifle kit with any stripped lower receiver, and you'll be ready to punch sub-MOA holes at the range. Includes all other components required for assembly.
