how i modified a nerf rival zeus mxv-1200 blaster.

modified (though impossible to discern from the exterior) nerf rival zeus mxv-1200 with additional magazine.

i've successfully modified the nerf rival zeus mxv-1200 blaster, removing practically all of its annoying mechanical and electrical "safety features ".  the following is how i did such....

this nerf blaster (like most nerf blasters) has a few "safety features" which i find annoying.  with nothing more than a phillips head screwdriver and a rubber band, these safety features can be defeated.  and unlike other nerf blaster modifications, they can be reversed (with nothing more than a phillips head screwdriver).

one "safety feature" is that of the blaster not firing without a magazine being loaded.  this is determined by a tab which is depressed when a magazine is loaded.

another "safety feature" is that of the "trigger lock" which is tantamount to a handgun safety.  the circle pictograph represents "on" while the 'x' through the circle pictograph represents "off".

this may or may not be a "safety feature", by intention anyway.  this firm rubbery/foamy barrel insert may be to make true the flight of the projectile.  if that's its intention, i believe it also, even if only slightly, slows down the speed of the projectile which to me sounds like something related to safety... despite being able to reportedly, unaltered, fire projectiles at near 70 mph .

to defeat all of these "safety features" (plus another not yet mentioned), the blaster has to be taken apart.  first, the battery tray should be removed.  then, the 15 case screws, as indicated in the enlarged photograph , need to be removed (or at least loosened to the point of removal).  the screws in the tactical rail between the flip-up sights have no bearing on the ability to take apart the blaster casing.

now the four screws, as indicated in the enlarged photograph , need to be removed.  this allows removal of the barrel and access to the tab which is depressed when a magazine is loaded.  it also allows access to the switch which while open, due to the "jam clearing door" being open, prevents the blaster from firing, another "safety feature".

flipping over the assembly which had been held in place by fours screws reveals a panel held in place by one screw.  removal of this screw and panel gives access to aforementioned tab and switch.

all of the plastic pieces and the spring can be removed.

using a rubber band, the switch can be kept closed.  this allows the blaster to fire without a magazine being loaded and with the "jam clearing door" open.  at this point, the panel can be replaced and secured with the screw, turning the assembly back around but not securing it yet.

update: i had used the same kind of rubber band to bind slack from straps on a backpack (i've since switched to velcro).  some of them have since broken but this may be due to direct and indirect exposure to sunlight, likely damaged from heat and/or uv.  they were in use since about the time as i made the mod.  for the first time since making this mod, my blaster has stopped working.  unsure if solely a battery issue, i took it apart again thinking the rubber band may have broke, it didn't.  it was solely a battery issue.  i did notice though that given how the one end is anchored to a post under a panel, it gets pinched.  it may be more beneficial to anchor it to the post outside the panel as shown in this enlarged photograph .

the barrel is in two pieces, an inner piece and an outer piece.  the inner piece will give access to the firm rubbery/foamy insert which is glued in place.  slowly pulling on the section of the insert exposed on the outside should dislodge it.

now the barrel can be put back together and placed back into the casing, as well as the aforementioned assembly, securing it with the fours screws.

the other half of the blaster casing has the "trigger lock".  removing the two screws, as indicated in the enlarged photograph , removes its functionality.

tightening the screw, as indicated in the enlarged photograph , which allows the "trigger lock" to swing, disallows just that.  then the blaster casing can be secured together again with the 15 screws.

and voila!
