Ok......what technology does the KAC have that the others don't.....seriously?
Sand Cut serrations on the carrier......sure that *might* be useful if you were in that scenario that requires it.
Their E3 bolt head or what ever they are calling it? I don't think its ever been proven thats more effective than he normal one.
Am I missing anything else?
Maybe you should fire up your google machine and find out for yourself, instead of being lazy and asking others to do it for you.
Since I'm already here you can start with:
Intermediate gas system coupled with propititary RE/Buffe/Spring that results in the softest shooting AR you can buy
Completley amidextrious lowers with QD cups built into the lower (older model) and started this before any other manufacture
One of, if not the best 2 stage trigger on the market. I put it up against any of my Geiselle's.
And as to your E3 Bolt comment.... Show me one E3 bolt that has failed or broken. Show me anothe rmanufacture that will Gaurentee their bolt for atleast 25,000 rounds, including SBR's.
You can do a search for broken AR15 bolts and you will find PLENTY. Do a Search for Broken E3 bolts and let me know what you come up with. Also keep in mind, that people who tend to Own SR15', shoot ALOT.
Most of the features and refinements you see on the AR15/10 platform are there beacuse KAC designed them over the years. They come up with the idea, R&D it, Test it, and put it to the market. Then companies comes along with the benefit of not having to do their own R&D, take those designs and principles and make pretty good guns. If it wasnt for KAC, there would be no MWS, GAP10, OBR, JP07,ect. Want to guess who used to work with KAC to come up with many of these inovations and designs? A man by the name of Eugene Stoner....... You know... The guys who invented the fucking AR15/AR10.
Would you like to know what SR as in SR15 and SR25 stand for?
Yes you missing everything.
