- High density polymer
- Grippy rubber butt plate
- For M4/AR-15 AEG & GBBR
If you're bored with your current stock and seek a change, the Specna Arms Adjustable Tactical Stock for M4/AR-15 is the style-up your gat needs! Made from strong, high-density polymer with a high-quality textured finish, this stock is based on an evolution of the OG "Crane" stock, also known as the SOPMOD stock.
Like the Crane, the Adjustable Tactical Stock features sloped cheek rests for a comfortable cheek weld when looking down sights, but unlike the Crane, this is a slimline stock with no internal battery compartment. This means if you're installing this on a rear-wired M4 AEG, you'll need to use your buffer tube to store your battery.
Also on board the Adjustable Tactical Stock is a pair of steel QD sling sockets and two "footman loop" sling slots, ready for whichever sling solution you opt for, whether modern or old-school. The butt plate is made from grippy rubber, ensuring it won't slip off your shoulder in wet weather or when you're rocking a plate carrier. Available in several colour options to suit any aesthetic taste, the Specna Arms Adjustable Tactical Stock for M4/AR-15 is a great way to make your M4/AR-15 truly yours!
