ProMag PM242 AR-15 Carbine Quad Rail Handguard

ProMag PM242 Quad Rail Handguard

The ProMag PM242 is a two-piece quad rail handguard designed for AR-15 carbines. It delivers the accessory mounting flexibility modern shooters demand without breaking the bank.

Construction & Design

Built from high-impact, glass-filled nylon polymer, this handguard combines durability with lightweight handling. Integral aluminum heat shield inserts protect your hands from barrel heat during extended shooting sessions—a practical feature that matters when you're running drills or working through ammunition.

Accessory Mounting

Mil-spec Picatinny rails run the full length at the 12, 3, 6, and 9 o'clock positions. This four-rail configuration gives you genuine flexibility:

• Top rail (12 o'clock): Mount optics, backup sights, or forward-mounted lights
• Side rails (3 and 9 o'clock): Attach tactical lights, lasers, or vertical grips
• Bottom rail (6 o'clock): Install bipods or additional accessories

Practical Value

If you're building or upgrading an AR-15 carbine and want solid accessory mounting without premium pricing, the ProMag PM242 delivers. It's a no-nonsense handguard that does the job.
