Here is the reference picture I used this time for it.
And easy access to my lego version.
Here is a shot with everything visible from the new muzzel break to the redone butt and everything in between. The gun is full size at 5'6" or 167cm (about 2cm too long).
The middle of the gun featuring the removeable magazine, the pistol grip, the spring loaded trigger, the spring loaded cocking bolt, and part of the scope. On this gun, the scope does not have a view hole due to it being a monitor in the game.
The front of the gun before the barrel with the weird rectangle thing in front of the scope, the 'camera' on the scope (the red piece), the bipod, the back end of the barrel, and the mini-barrel-thing under the barrel.
The new muzzel break with the two holes on the side to channel some of the explosion back towards the operator and reduce the recoil.
The middle again featuring everything it did before but this time with the magazine out and the gun resting on the back and the two display stands.
The spring loaded cocking bolt being held back. When released, it return back to the front as fast as the rubber band can make it.
Lastly, me holding this massive thing! I am 5'11" and this gun being 5'6" makes it 'rather' big, even for me. Not sure what it weighs, but it is a lot for legos.
I hope you have enjoyed this and will rate it 5 stars!
