    I think you underestimate the machining needed to make the slots.

    Also pricing is not just a factor of the amount of work required to produce an item.
    Tell my tale to those who ask. Tell it truly; the ill deeds along with the good, and let me be judged accordingly.

    Excuse my sceptisism, but it cannot be more machining than a quad rail requires. Comparable pricing doesn't pan out.

    Agreed. If the amount of work required to produce a quality key mod rail dictated the price then they would be cheaper.

    Geissele even conceded that the machine time on the Keymod slots was a machine time factor. Honestly.. if the KMR rail cost as much as a DD RIS II, I wouldn't have bought my 10.0. I never owned previous favorite rail, the RIS II because it simply exceeded the price that ANY handguard should cost.

    Price and Weight are the two major plus points for the KMR.

    I typically wear gloves anytime I'm shooting so I suppose it wont be a problem for me when I get one.

An open rail in theory should allow the barrel to cool faster by allowing more air movement. On the other hand a quad rail should take longer to heat up due to its additional surface area and mass. Personally I think this heat thing is being over played! GH
    It most likely is being over played.. I've been shooting with tube handguards for the last few years and even after a few mag dumps the rails arent hot enough to be a problem when wearing a pair of gloves and could probably still be handled without them.. Looking forward to getting s BCM KMR upper soon and finding out for myself.

    Personally, I'm not all that wild about keymod, and the KMR is still hard to overlook as a rail system by itself (in price and weight alone). I understand the keymod system, and I still remain rather neutral about it. That said, I just wanted to throw in the following for the OP.

    About 2 or 3 years ago, my spotter and I were moving through some dense brush just prior to a SW service. Somewhere in that path, I snagged my tape switch cord and it pulled hard enough to render the controls and light (by extension) useless. Knowing I would be needing my white light on the rifle, I pulled the X300 off my duty pistol and clipped it to the rail on my rifle opposite the deadlined Scout. Same goes with my vfg and bipod on that rifle. I like the ability to add or remove either on the fly, without tools.

    While the Keymod is still in it's relative infancy (on weapons), it currently lacks the universality that standard rails have finally just now reached. A new interface represents an investment for the end user....some are cool with that, some aren't.

    I keep unoccupied rail sections on the KMR for that reason. I see what you're saying.... but I have at least one rail section on one or both sides for similar reasons, and a rail section on the bottom for bi pod clamp on.

    True, but to me the whole benefit of the keymod is to do away with unoccupied/unnecessary rail. Again, while I get the keymod theory, bolt-on rail sections don't thrill me either. My situation described above is not a deal-breaker scenario by any means...it just means that if running a KMR in that capacity, I would have to put more thought into my backups/alternatives for contingencies such as that.


    Also, I don't get why so many people are worried about the heat, when it's the cold that concerns me. Often times around here, cold and damp go hand in hand too. Gloves or no, cold, slick (and possibly wet or damp) bare metal rails/handguards are no fun.

    By leaving a rail section or two on the KMR, you have say.. 6" of unused rail space. You still have approximately 30 inches of slick surface (bottom and sides combined) on the middle of the rail.

    You could also simply keep a rail section and wrench stowed in your gear. The real problem is that your pistol isn't keymod light attach!

    This is why I would consider a URX 3.1 with Keymod in place of the slicks the perfect rail. The main place we need rail sections are the top, and the last 2 inches or so on the muzzle end on the sides. By leaving Rail sections there in the base design you give people those options.
