5 of 5 Great starter gun November 27, 2015
Reviewer: Michael H from San Diego, CA  
I have just purchased my fourth one of this model.  Had purchased 3 for myself, my son and however came along with us.  Had to drop the spring to M110 as the factory model was shooting to hot (440FPS) for the local fields in southern California. The battery compartment is small but I'm using 7.4 Lipo's which fit well and last the day for me.  I have gotten several complements on the quality of these guns. No failures so far.

4 of 5 JP M4 April 1, 2015
Reviewer: Jeff gregory from cocoa beach, FL United States  
This is too soon, just got it. The rubber ring serves no purpose (as stated in the manual) as it does not open or keep closed the battery compartment. There are two screws that require a screwdriver to get the battery compartment open and closed. The batter barely fits. Gun is nice, good power, heavy, but the entire battery experience is off putting. No way you should need tools to get the batter in and out.

5 of 5 Great gun March 9, 2015
Reviewer: Bryce  
had the gun for 3 days so can't really say much long term durability but so far it's a great gun.  It is kind of heavy and I would definately recommend getting a grip, I would check ebay they are the cheapest place I could find them at.  Also I would 100% recommend the tenergy smart charger.  The charger it comes with isn't good at all and could potentially ruin your battery if not used correctly.  I bought an extra battery along with the gun an 1100 mah one for 10 bucks and would completely reccomend it as the battery it comes with is extremely hard to put in and make it fit vs the one I bought is a tad bit smaller.  The majority of the gun is metal which is nice durability wise and the only plastic parts (the stock, grip,reciever) are all made of an extremely durable plastic and will not break.  Overall amazing gun.

Mostly metal
Great fps
Stock is very sturdy
Iron sights are nice
Hop up adjustment

Pretty heavy (an ebay grip will fix this)
Semi loud

5 of 5 Excellent Service November 5, 2014
Reviewer: E. Harris from Lufkin, TX United States  
I bought this airsoft gun for my son's birthday.  I had a little confusion with placing my order.  The customer service I received from this group exceeded my expectations.  The price was competitive.  My son was thrilled, and the quality of the gun is good.  I would order from this company again.
