Our take:  It's been a long wait for the 2010 A&K MK43 Full Metal AEG, but we're glad to inform you that it was well worth it.  The A&K MK43 is the latest and greatest from A&K, the originators of the M249-series, and with it comes a history of excellence.  This variant is one of the most famous military squad automatic weapons in recent history. 

The A&K MK43 offers a lot of unique and down-right cool features at a reasonable cost.  Our favorite is hands down the adjustable ROF (rate of fire) switch located underneath the barrel.  With a twist of this switch, you are able to actually INCREASE or DECREASE the rate of fire of this rifle to best fit your shooting needs.  Adjusting this switch accordingly produces a varying rate of fire, from 11-20 RPS (rounds per second).  It's an extremely useful and neat feature by all accounts, and is STANDARD on the A&K MK43.

As it so happens, rate of fire is one of the MK43's most outstanding attributes, as it tops out shooting over 1,100 rounds per minute on fully automatic mode!

An adjustable length/retractable bipod also comes integrated onto the gun itself, as users will find it very useful in times of varying Airsoft combat scenarios.  There is also a vertical foregrip hand guard at the front of the rifle that is every bit as unique as it is functional.  Overall length of the rifle has been shortened from the original M60 to provide superior manuverability and improve overall balance.

The drum magazine holds a whopping 4,000 rounds of BBs, so you can pick off your opponents all-day-long.
