The ACE M4-7 features a light carry weight while retaining superior strength and durability. The specially designed extension tube is significantly stronger than other collapsible stocks. Requires a standard carbine length buffer and spring (not included). Stock has a stop screw and a shim screw. Until these are installed, when the stock is extended, it will come off the extension tube.
This is not a defect - it is the way the stock is designed. Once the screws are installed, stock will function as expected.
Stock uses the carbine spring and buffer -- not included.
Stock does not have a separate recoil pad
Gusset reinforced receiver extension tube reinforces the receiver.
When gusset screw is tightened, the gusset is pulled into the receiver for additional strength.
