I received Nighthawk's KYDEX cheekrest in Saturday's mail intact & looking good! The HD USPS box & wadded newspaper packing did the trick. He was wise to put one "lip" in the design; two would be completely unnecessary & a PITA to remove. The KYDEX thickness is perfect & the formed angle for a pinch effect works extremely well. The cuts, beveling, shape & size are right on the money. I'd be willing to bet that Kel-Tec CNC makes topcovers that are virtually identical regardless of vintage. The cheekrest WILL fit ALL RFB bullpups with ease & stay put. I'm sold on the KISS Principle... I LOVE simple. I hate to modify a weapon permanently & Nighthawk's design allows a professional appearance w/o drilling, cutting or otherwise modding the host firearm. Pushing the cheek rest down & snapping it in place took all of about 5 seconds without any drama for the intimidated DIY'r. There is absolutely NO movement; it's not going anywhere until you decide to snap it off. It's has a pretty aggressive hold & will not slide back & forth or up & down. It's a precision cut with nicely dressed edges.
Darn, if this thing doesn't look totally awesome. Kel-Tec shouda coulda woulda... but you know Kel-Tec & how they view accessory priorities. That's how an RFB "should" come from the factory. I would imagine that every owner of one of these innovative bullpups will want one.
I'll try to get some high resolution photos this coming week of my gun with it installed. Maybe, I'll put my Raptor NVD on for grins! I need sunlight for decent pics & it's been raining off & on. Bottom line: I HIGHLY recommend this product. I haven't had a chance to put it through the paces of live firing, but all indications are a total WIN! Kydex is an extremely rugged material & the thickness that was chosen for fabrication should take a ton of abuse without damage.
