LAPCO Locking Feednecks
By Bill Mills - Oct 2005

While LAPCO Lockers has a nice ring to it, and might bring locking differentials or hubs to the mind of four wheelers, LAPCO Paintballs’ locking feednecks replace a paintgun’s stock feedneck and clamp down on a loader, ensuring it won’t go AWOL in the middle of a game.

Like most of LAPCO’s product line, the feednecks are available for a variety of paintguns including Matrix, Shocker, Impulse, Piranha, Intimidator, and AKA.  Slip over versions are available to fit many paintguns, and a Spyder version is also available with flanges to allow mounting screws to hold it in place.

For review, a feedneck was placed on an LCD Matrix.  Installation involved removing the breech from the paintgun, and warming it (not overheating it) with a torch to soften the thread locking compound holding in the existing feedneck.

It should be noted that the feednecks are produced in various sizes for various models, the Matrix neck used was quite short, measuring just over one and a half inches in height when clamped.

As the feedneck is shipped dry, it was disassembled and very lightly lubricated with a small amount of Battle Lube paintgun grease.  This made opening and tightening of the feedneck go much more smoothly.  After cleaning the breech, a small amount of temporary thread locking compound was applied to its threads and the feedneck screwed into place.

The clamping system is a simple collet arrangement.  Eight flanges extend from the base, and are tightened inward as the outer ring is screwed downward.  Their interior surfaces are ridged for a sure grip.

Rather than a knurled surface, as with many brands of clamping necks, the outer ring has a series of smooth edged vertical grooves that provide enough grip surface to loosen it without tools even when snugged tight.

The LAPCO Locking feedneck securely held HALO, Riochet, and ViewLoader loaders though the HALO’s only fit after having been sanded.  Its low-rise placement kept the hoppers tight to the body of the Matrix.

The drawback to the original model LAPCO feednecks is that they are quite hard to find.  LAPCO has halted production of this design, and is gearing up a second generation which is expected to be available in time for Christmas 2005.  The new models are also planned to include the capability to handle unsanded as well as sanded HALO feednecks.
