The M14 presents us with the Version 7
Mechbox in two version's. The top photo is a G&G type V7 and the 2
ND picture presents an
AGM version M14 which is widely known as a TM clone. The
mechbox parts are virtually Identical in size and shape however some clone parts are manufactured from cheaper materials. This can be both a good and bad thing for
airsoft consumers as the clones are much cheaper but will need repair or part replacement sooner than the higher end
AEG's.
The G&G version 7 has some bugs that need to be worked out in my opinion. The design is awesome and simple when compared to the more common V7
mechbox shown below but the selector switch lever has to be modified to obtain a proper trigger pull. On the other hand you have the more common V7 that host a whole slew of levers, springs and switches on the outside of the
mechbox that need to be removed before you can even get to the internals. The M14
variants on the market today are precise, finely tuned
mechboxes that the novice should not
attempt to repair.
Inside the V7 you will find an
in line gear train that differs from other
mechbox versions. The m14 family of
airsoft guns feature specialty parts that are specific to the version 7
mechbox. The tappet plate, gears and trigger switch assembly are specific to each model. All in all the v7
marui style
mechbox is a solid well built long lasting design.
To upgrade or repair a V7 m14 be sure you have the right parts. You will not be able to put your M4 internals in this
mechbox. Shimming is extremely important to the life of your
mechbox and should be done by a qualified
Airsmith or someone
knowledgeable in this area. Poor shimming can get expensive quick in the cost of other repair parts. Properly maintained the V7 is an awesome design delivering as high as 400 FPS
BB's at a rate of fire exceeding 900
bb's a minute. See more detailed pictures of M14 V7 repairs at
