    This comment was submitted from Mr Morgen while the web site was being updated. We are happy to post his review! :

    I purchased this rifle because I saw some of Mr. Keller’s videos and related to his philosophy on the basics and training. I have a friend with a similar background who explained to me what they had at their disposal with regards to tailoring weapon systems, and when Mr. Keller said “this is the best rifle I have ever shot” I was immediately impressed.

    My background. I have been firing the AR platform for 30 years from the M-16A1 to M-16A2 to the M-4, and personally some of the Ruger, Daniel Defense, and M&P AR offerings. While those are all capable rifles, The “Bob Keller” rifle is unlike anything I have ever experienced.

    I have only zeroed it with the MBUS Pro(I prefer them over the regular MBUS due to the smaller front sight post, and well.. they are metal) and I mounted a Leupold LCO (pricey but my other optic is an AimPoint Comp-M4 and the LCO is superior IMO) and done a few “ready up” drills or “get sight on target and shoot” drills.

    First of all, at 25 yards with iron sights my shot groups were a thumbnail apart. With the LCO I suddenly found out that my fundamentals were weak so when I focused and paid attention, my final group was 1/4″ with 62 grain ammunition.
    This rifle is very light, and feels like a precision instrument. The fit and finish is excellent, and the balance is hard to understand until you have held it. Due to the gas system and the muzzle brake, there is basically no recoil. With other rifles I shoot, stabilize, reacquire the target and fire again. With this rifle I fired and then realized i was still on target, shocked at that fact, then realized I could fire again. I believe I am above average in skill, but after firing 120 rounds through this rifle I realized I was slower than this rifle. I did not have the opportunity to zero the rifle at 100 yards as I like to, (static range and too many yahoos the day I went) but this is simply an excellent weapon.

    This is the first AR type rifle I have fired that requires me to up my game and training in order to maximize its capabilities. Thanks to the manufacturer for creating such an outstanding firearm, and thank you to Mr. Keller for being an individual of integrity and not putting his name on something that wasn’t excellent. I highly recommend this rifle. Now that I have fired it I am not sure I will be able to use my other AR again, because this is such a fantastic work of art.

    Love the rifle. It is so smooth to shoot. Wife and I took a class from Bob this past weekend. She used the SOT rifle in it. She was saying how she could keep the red dot in the small circles even during recoil. She is a new AR shooter. Now spoiled with this rifle. Have to buy another one so I can have my own. She is not giving it up. Great service from SOT. Very nice owners. Can’t wait to get more from them.

    I know Bob personally…..He was and will Always be one of my Best Friends and men that I served with.
    I would fight satan with a plastic fork with this man.
    I will Always have his six.
    If Bob says the weapon is good….I can assure you that the weapon will be good.
    End of story……
