Granted it's very cool, but a tad steep on price.
If I ever get an AR-15 I'll get one of those.
An interesting concept. Neat. I like that idea way better than the AR Combo Tool multitool (Image removed from quote.)
Hmmmm, apparently its also called the MK-16 Combo Tool. There's a video too, but I haven't checked it out yet: http://www.cjweapons.com/
I also recently found myself hunting for a multi-tool that was outside the box but fit the bill. Take a look at a review I did on this option. http://m4carbine.net/showthread.php?t=32713 My dad has one of the samson field survivor. I havent had a chance to run it through its paces, though I dont have a stock grip. I've got a magpul MIAD which carries an extra bolt/firing pin. I'll be glad to post the review here in full if theres interest.Teaser(Image removed from quote.)
