Black Aces Tactical "Impractical" fix mod / Moss 930

[xtriggerman]

Just did a complete reconfigure on a Black Aces rail for a guy's 930. The ridiculous thing about putting this other wise nice rail on your shot gun is it must be completely removed to give the gun a standard break down cleaning. That entails removing 4 screws & washers at the FCG (that incidentally freeze the action if to tight), and also remove the barrel/mag block up front by its 4 screws and only then can you get the extended mag tube off and FCG out. Pure ridiculousness. Soooo some serious mods were in order to allow the original take down procedure to be performed while not disturbing the rail system.
   Heres the stock unit advertised  http://www.blackacestactical.com/_p/prd3/2394217881/product/mossberg-930-quad-rail

 In this shot you can see the saddle plates are cut off and the rail is lowered by nearly 1/4" onto the top of the receiver.

To get the rail anchored solidly, a alloy filler block was machined to precisely fill the tunnel space under the rail and it and the rail were drilled for the Mossberg scope base pattern.

Here, the bottom half of the wrap around rail is cut off and the rear portion of the side rails are trimmed forward so you can get your fingers on the mag tube nut. The attaching split block there hits the round file...

 The heart of the mod is to allow the barrel to be pulled directly off the gun as you would normaly but yet once its in placed, it would fix the rail solidly in place and provide a recoil plate so the rail could not possible stress the scope mount screws in heavy recoil situations.
  Luckily, Mossberg made the integral muzzle break exactly 1" in diameter at this point. I used a Ruger steel med ring as my rail anchor with a heaily modified base that acts as a 0 tolerance claw to the front edge of the rail.
 
 
 Once the barrel is seated within the receiver, the claw fabricated on the bottom of the Ruger ring locks the front end of the rail down with zero wobble.... Rock solid. The owner really loves this thing now!
