FS:***TACBLOCK One-Piece Magazine Block for M16

[Tacblock]

We manufacture and sell one-piece magazine blocks for the M16 which are used to convert the weapon from 5.56 mm to 9mm. They are held in place by the magazine catch on the receiver and a detent ball so there is no receiver drilling and no set screws. The block holds the bolt open after the last round for tactical magazine changes. Visit our website at http://sites.netscape.net/tacblock/home

Nifty product and an advancement over Colt's modification, but sales are posted in another forum.
