B5 Systems AK Stock 4.5mm – Plum Polymer for AK-47/74 Rifles

The B5 Systems AK Stock 4.5mm in Plum delivers enhanced shoulder stability and cheek weld consistency for AK-pattern rifles. Engineered with a modern ergonomic profile, this stock reduces felt recoil and improves sight alignment for faster follow-up shots. The 4.5mm folding trunnion compatibility ensures proper fitment on standard AK variants while maintaining a secure lockup when deployed.

Constructed from reinforced polymer with a distinctive plum finish, this stock installs on AK-47 and AK-74 rifles equipped with 4.5mm rear trunnions. The textured surface provides positive grip in wet or cold conditions, and the material resists impact and temperature extremes. Installation requires basic tools and follows standard AK stock mounting procedures. Verify your receiver's trunnion specification before ordering—this stock is designed specifically for 4.5mm folding trunnion systems.
