Key Features – Maxim Defense MXM47575 CQB Buttstock Assembly
Ultra-Compact CQB Stock for PDW and AR-15 Builds
The defining trait of the Maxim Defense CQB Buttstock Assembly is its extreme compactness. At its most collapsed, this stock adds only 5.35 inches to your AR-15, making the entire platform significantly shorter than a rifle with a traditional carbine stock. Buds Gun Shop+2Palmetto State Armory+2
This compact profile is ideal for:
Maneuvering around tight corners and doorways
Working inside vehicles or confined spaces
Stowing the firearm in discreet storage locations or compact cases (where lawful)
At the same time, when fully extended, the CQB stock gives you a full carbine-like length of pull so you can shoulder and control the rifle comfortably for precise shots at longer distances. Palmetto State Armory+1
Pull-to-Deploy Design – No Buttons, No Hassle
Unlike traditional collapsible stocks that rely on small buttons or latches, the Maxim CQB stock uses a simple pull-to-deploy mechanism. To extend the stock, you just pull it straight back—no need to hunt for controls under stress or in low light. Buds Gun Shop+2Palmetto State Armory+2
Key advantages:
Extremely rapid deployment: From fully collapsed to shouldered in one smooth motion
Intuitive operation: Fewer fine motor skills required, beneficial in high-stress scenarios
Clean, snag-resistant exterior: Fewer protruding levers to catch on gear or clothing
Once extended to your desired position, the stock locks solidly into one of four adjustable positions, letting you tailor length of pull to your body size, armor, or shooting stance. Palmetto State Armory+2Gun Values Board+2
