When it comes to building a compact AR-style pistol with maximum firepower and style, the 5 inch ARP kit is quickly becoming a favorite among gun enthusiasts. At AR15-Overstock.com, we’ve seen demand skyrocket for these ultra-compact kits—and for good reason.

What is a 5 Inch ARP Kit?

A 5 inch ARP kit typically includes:

• A 5" 5.56 NATO barrel for close-quarters performance

• A compact M-LOK handguard (usually 4" or 5")

• Forged or billet upper receiver (standard or side-cut options)

• Buffer tube assembly

• Lower parts kit

• Optional BCG and charging handle

• Custom cerakote finishes available

"ARP" stands for Advanced Rifle Pistol, and this configuration is built for shooters who want a short, maneuverable platform without sacrificing the reliability of the AR-15 design.
