"Got one of these to use on my G&G Predator since the standard stock won’t fit the TITANPower batteries. Overall happy with the build quality, there are a few mold lines and there is a little wobble on the buffer tube but nothing major. I love the latch release on the stock, super easy to open. Plenty of space in this stock as well. I run the Titan 11.1v nunchucks and they fit in just fine. The stock won’t click on the position closest to the receiver, but that’s not a big deal for me.

I purchased a PTS EPS to go on my Avalon Calibur and between the two of them for a stock that’s $20 cheaper and waaaaay easier to open the compartment, this would be my go to. Think I’ll pick one up for my new VFC Block II as well since most of the PTS is perpetually out of stock.

"Fantastic battery stock. With a full buffer tube, you can use a Turnigy 2000mAh 3S nunchuck battery. The latch on the back is solid and easy to open, even with gloves on. This stock is my new go-to for a crane style battery stock. For only $25, it's a steal.

"Throw away the BBs that come with it, or better yet use them to practice racking and rapid fire. I almost returned the gun cause it was wildly inaccurate, the BBs that came with it would travel about 20 feet then arch up (yes UP!) about 20 ft. I weighed the BBs and realized they were .12g, I loaded the gun with .20g and it shot noticeably better, but still arched up about 4 feet around 40 feet out. I then loaded it with .25g and it shoots almost perfect, very nice 8-10 inch spread about 50 ft out.
