If you're looking for the ultimate close-quarter M4 AEG, here it is. The Elite Force M4 CQC is not "just another M4" as many might think. For example, how about reinforced internal parts or redesigned external furniture like the 6-position crane stock with a unique simple-access battery compartment? Not only does our M4 CQB come with a micro-switch trigger inside for snappy trigger response, but the extremely compact size of the rifle itself allows to the shooter to move rapidly through tight areas in order to achieve the objective and take down any targets along the way. This particular model has gone through seven (yes, 7) generations of improvements both inside and out. We care about the shooting experience of our customers and as a way of demonstrating that, we listen to feedback, review and revise, test and retest, ultimately creating a better product so that you can enjoy a better class of airsoft products. We also back our work with a 60-day replacement warranty just in case. Buy with confidence, shoot with pride.
