Video Added! AEG (A&K) Atlas Custom Works MK46 M249 Saw Machine Gun Airsoft Gun

Description

EBAY DISCLAIMER: This is an airsoft gun THIS IS NOT A REAL GUN.  Orange tip removed for photos, but will be installed for shipping, original will be included.
EDITED AND UPDATED: Added video and corrected mistakes in listing (green sack mag is brand new!).  Video should populate in a day or two after ebay "reviews" it.
This is an Atlas Custom (A&K) polymer receiver MK46/M249 Airsoft gun.  It has been modified as described below and used but functions really well.  It has a purposefully worn camo paint finish that really looks good in person.  I have 100% feedback because I try to explain everything in extreme detail.  Please read and ask questions as needed.
NOTE: Fake/prop bullets are not included
due to regulations but will add metal connector links so you can make/add your own.
The good:
Shoots great! about 330FPS with .28/.30 bbs.
Quick change spring system.
13+ pounds fully loaded!
aluminum aftermarket hop up chamber and bucking.
Red dot sight was 5 and is a shake awake/auto off design intended for real steel.
Krydex multicam padded sling.
camo sack mag works best with a pressure switch as the sound operation on this mag doesn't always pick up the gun firing and keep feeding. The pressure switch lets you control when it feeds. It uses included JST connector rechargeable batteries. (you'll need a charger/connector adapter)
Green sack mag is brand new and only tested, never used in a game!  Works perfect! (sorry i had my information wrong when i originally wrote this.  It is literally brand new from Evike and functions as it should.)  Uses the included (lipo and nimh) rechargeable style batteries with JST connectors.
Large 1500 round green drum mag works great! uses 2 AA batteries The sound activation on this mag works amazing.
includes most of the original parts when purchased new
includes pressure switches to operate the electric mags manually if needed, never used, sound activated works great!
includes 11.1v 3s 2000mah lipo in handguard to power the airsoft gun
Real grip pod deployable bipod grip included
I replaced the plastic rear iron sights with a metal/adjustable model!
The bad:
This model is known to have a loose cover for the battery compartment which is inside the lower forgrip.  To fix this, I have zip tied it closed and can connect/disconnect the battery by quickly popping off the barrel to access connecters and for charging.  You could just as easily clip the zip tie and swap batteries and rezip tie back on. This poses no issues and has been used this way since purchased.
This model is also known to have a tilted hop up which makes bbs curve slightly off center.  This has been fixed and is part of the reason the aftermarket aluminum hop up was added.  Gun now shoots great and straight.
The drum mags are known to be fragile around the feed springs because the external springs contain the wires for the sound operated mics.  Just know that you should try to be gentle when loading and unloading them into the airsoft gun.
The receiver is polymer and not completely full metal.  Many parts are metal but it is not the full metal version.  This version can be looked up with the search term "Atlas Custom Works MK46 M249 SAW POLYMER RECIEVER AIRSOFT LIGHT MACHINE GUN AEG - BLACK".
Having said all of this, the airsoft gun operates amazing and shoots great as well.  Please purchase with confidence that my information is correct and that the airsoft gun will shoot just fine, understanding the details above. Consider it a project if you want and add, subtract, change whatever you like to make it your own design.  I tried to replicate Tig's mk46 from the movie 13 hours.  What you see is included.  If it is not in the pictures, it is not included.  Again, ask questions.  Also shipping will be ground shipping due to lipo battery regulations.  This could mean 5-7 days in transit.  Shipping is to the continental United States only, and you are responsible for knowing whether you can own this due to local laws and regulations. Airsoft gun will be shipped with orange tip, painted one will still be included.
