Things I liked:After a lot of research and reading, I bought two of these (one for my 10 year old son and one for me to defend myself LOL). Build quality is great. Solid on the outside. Internals are metal, high quality, and fully repairable and upgradable. I'm an engineer so this was an important criteria. Don’t forget to buy 9.6volt 2000mAH batteries (or higher maH which gives you more operating time). The 2000maH batteries easily survived through 4-5 hours of airsoft at a birthday party, which finished with full auto target shooting, magazine after magazine, until one rifle stopped working-totally dead. The other was fine. I received the inoperative rifle and discovered the batteries were too hot to hold! I let them cool for about 2 hours, plugged them into the charger, and the next day the rifle was good to go. I don’t know if the batteries were the issue or if the rifle has some sort of thermal protection as the motor heat could also be felt through the pistol grip.
If these two rifles can survive 5 hours of 10-11 year olds running around a woods, hills, dirt and dust along with a bunch of full auto shooting, then they have passed the ultimate quality and durability test.
I highly recommend these rifles as a quality alternative to anything available at the big box stores…and I imagine Pyramyd has made some airsoft sales to Colorado Springs and Monument, CO recently as a result of these rifles' performance. Things I would have changed:Make sure the lockscrew on the adjustable stock is secured (it's the nut that that the stock lever pushes against to let you adjust the stock). We lost one nut at the party. Made my own replacement with parts from the local Ace Hardware Store and loctited the nut on the other rifle.
The front sight is not removable---so if you remove the rear sight/handle to install a 30mm red dot sight, you may want to purchase a weaver riser. It doesn't bother me or my son, but the red dot is blocked by the front sight without a riser.
Buy lots of ammo--I only bought 20,000 rounds of biodegradable ammo...and it's all gone---that's not including what the 10 kids brought themselves to the birthday party. What others should know:Bottom line: GREAT Airgun, adjustable stock great for adults or kids, just the right weight.
You should buy at least two "normal" capacity magazines as many places do not allow high capacity magazines. Of course, we are also looking at a 5000 round magazine.......I believe one battery may actually suffice for that!
Also--do NOT use these with only eye protection---USE a FULL face mask that protects your eyes, face, teeth, and ears This is very important. Paintball masks work very well.
Things I liked:Fit great on these rifles

Things I liked:Survived a birthday party (two batteries sets, on per rifle) for 4-5 hours of nonstop play by 10-11 year olds. One got too hot to hold, but survived to play another day!
Works great in our rifles
Things I would have changed:Perhaps a thermal cut off in case of too much full auto firing.....the kids had a blast!
Things I liked:Bought 4 bags....and NO jams after shooting all of them 20,000 through these rifles
and a bunch of others airsoft at a birthday airsoft party.
Can't speak about the biodegradability, but expect that it will take at least a fall/winter season here in Colorado for them to get enough water to disappear...
Green color helps the pellets blend in with the woods greenery.
