Just like the rest of Lapco's accessories, these front blocks are made to very exacting specifications. LAPCO's tolerances are very tight making this a beautiful fitting accessory for your TPX paintball pistol. TiPX and TPX are the same thing, just a name change from Tippmann.
With the mil-spec picatinny rail on top of your gun now you can mount a laser sight, scope, or tactical flashlight to the top of your gun. The molded rail is a special fiber reinforce composite material that won't absorb moisture or freeze so once you get your sights zeroed in, they'll stay that way.
