"I bought this stock on a whim and I was pleasantly surprised. The battery compartment is very easy to access and it can accommodate both stick and numchuck style batteries. It installs on your buffer tube easily and locks securely. It appears to be constructed well, but only time will tell. For what you pay I'd say they're worth it.

Be aware that these will not work with square PEQ style batteries.

"Ordered. Got order. Order part work very good. Many full auto using cheating children at the airsoft field suffered pain. I am a happy customer.

Best part of this stock is the battery compartment and how to access it. No screws or clips necessary. Just press the button and fold the shoulder plate back to swap batteries quickly.

Excellent m4 style stock to improve/repair a airsoft rifle, 0/10. Will buy again.

"Solid stock, looks good, a little heavy but that helps balance put the weight of attachme t on my handguard.
