Review

For experienced players only, a great Marui Clone M4A1 released by Guarder. Pre-upgraded internal and is fully upgradeable. For all the Tokyo Marui Clone M4A1 style AEG in the market: R6 does not have a Marui compatible magazine, the BOYI metal gear box m4 have extreme bad quality control, ICS and Classic Army are twice the price, so if you are looking for a full size M4A1 with metal gear box and is Marui compatible, this is the one!

The gun is pre-upgraded and it is a very popular model. We had a few returns from the past because some buyers refuses to read the description and tries to use a 8.4V battery on the gun, so we are now INCLUDING the 9.6V battery with the gun package. (AIM M4 does not come with battery from the manufacture, but by buying it from us today, we will include an intellect 9.6V 1200mah high output battery!)

We carry this AEG because players want pre-upgraded, Marui compatible M4A1 style AEG with metal gear box at low price. A complete M4 gear box will cost over $150. Not to mention the hi-cap magazine and everything else. An AEG will virtually never break if you know how to replace the parts that wears off or gets mis-aligned. For this reason we will not carry any warranties on this product. All sales are final.
