This seller stinks! We ordered this item on May 31st with a promised delivery date range of June 9-12 which is a long time in my opinion. The worst part - today is June 14th and it's STILL not here! Now the delivery date says June 17th. My son is extremely disappointed. I feel like we should get our money back and get to keep the item. Do NOT buy from this seller!
this is a really good lil pistol. it has great weight and shoot hard. definitely worth it for the money.
i read the description and i was mislead into thinking that it came with bb's as well as a few C02 cans as well as the cheep sight and box.it dosnt. so just know your only buying the gun
i ordered this gun and it came quickly in the mail. people say its missleading and the gun ships alone. i find this is only part true. about 3 days after i got the gun i got an email saying my kit shiped in the mail and is curently in transit. just got the kit today. gun is amazing. definatly recomend this gun.
When I got this gun I. Sounded like it was going to be cheap and stinck but it is the best gun I have so do get this gun
Very surprised to get the 2 grenade loaders and Laser/flashlight(The light/laser retails for 40$). Everything works perfectly and am extremely happy.
This item takes forever I still don't have it  when it's going to get here this takes for ever. Uhh
This is a great product, I love it. It will shoot through both sides of an aluminum soda can with a heavy pellet. Trigger pull is great, not too crunchy, a bit longish, but accurate. Good training device.
This is a good gun it hits very hard  I made 2 of my friends bleed and its c02 as it has 400 fps and metal 15 round mag I have also sawed through a can using .20 grams great gun only thing bad is it only has 15 rds other then that it's amazing
