Easy and Quick

I was browsing the web looking for a range toy and stumbled on gunprime.com. They had great prices on everything and the best price I’ve seen for what I picked up. I was told that I would receive my package in a week but I got it in 3 days. No hidden shipment fees or trying to sell me on something. They also kept me updated every time there was a change and progress with my order. I will definitely be shopping with them a lot more in the future.

Overall it’s a good price

I done had my ar pistol for over 4 weeks if you ever wanted to own a ar pistol but can’t afford it for 700 to 1000 dollars this might be your interest

200 rounds at range

This thing is fun to shoot from the first round! Shot between 150-200 rounds with no issues or malfunctions. The handguard is metal and heated up within that range of rounds. To be expected. I wish I had my glove to shoot a few more rounds! Overall very satisfied with the look, function and price of this firearm. Great deal!
