Our take: This tactical metallic rear stock, which is adjustable (folding), is a great add-on to your M4 or AR-style Airsoft rifle.
Especially functional when modifying your weapon to be more CQB-friendly (folding rear stock effectively reduces your weapon's length in an instant). Made out of durable ABS composite and metal, it is sure to last. A great deal overall, it's a great buy and a must if you want to have a solid and affordable folding rear stock.
Comes with the stock itself and all necessary mounting pieces. Buyer responsible for mounting/installation.
