How to- masterkey m870 on m4 ris

[clayton]

Just completed a sucessful masterkey breaching system for the m4 ris.

you will need
-x4 scope ring rail grabbers
-x1 DE/ m3000 m870 or maruzen springer shotgun w/ris
-x1 screw driver

step 1.
place the bottom rail of the m4 flush with the rail on the shotgun.

2, place the 2 sets of scope rail grabbers on each side of the flush rails on both guns together.

3. screw the flush rails together in order to fit under the barrel of the m4
note- you may need to saw a part of the grip assembly off of the shotgun befor doing this. and, you may also first need to remove whatever stock/ or grip yo have on the shotty with a screw driver

What's the point of this really?

[clayton]

the original post is supposed to be a toutorial for anyone who ewants to take the cheaper option in a masterkey , rather than going the 300+ route with g&p and maruzen. the point for this undermounted shotgun, is to provide a quick transition for cqc and breaching, rather than carrying a shotgun seperate that will get caught on stuff, snag, and dangle.

I thinks it's a pretty cool idea plus i've never seen it done on an airsoft gun
