Description
ACM M4 Sideways Stock Kit (Black)
This black ACM kit is listed as a sideways stock kit for M4-pattern rifles. The name points to a stock that sits or folds to the side, an arrangement popular for making M4 replicas more compact for vehicles, storage and close-quarter play. Please check the product images to see exactly how the kit fits and what parts are included.
M4 replicas are the most customised rifles in airsoft, and the stock is one of the easiest areas to change. A different stock setup can shorten the rifle for transport, change the way it sits against your shoulder, and give it a distinctive look.
Why change your stock
A more compact stock arrangement makes a rifle easier to carry in a car, store in a smaller bag and move around tight indoor spaces. For CQB players, a shorter overall length can make a noticeable difference when moving through doorways and around corners.
The stock area on many M4 AEGs is also where the battery is stored, so check how this kit affects battery space before you order.
Fitting
If you are not confident working on your replica, ask an experienced tech to fit it for you. Always remove the battery or empty the gas, and remove the magazine, before starting any work. Because parts like this are made for specific replicas, compare the product images carefully with your own replica before ordering, and ask us if you are unsure.
