Why is deflection important to you....to me, it's in the use of aiming devices such as lasers etc. What causes deflection....here is where it gets sketchy....so your results may vary.
Type of fitment of rail onto barrel nut.
Type of barrel nut and how long, and how much bearing surface it has to the rail.
Upper receiver, how tight the barrel extension goes into the upper, concentricy of face of upper, threads, torque value, heat, demential mass in the upper, etc...can be variables.
Type of fitment between the lower and upper.
Basically if one were to test the "flexibility" in a rail not attached to a barrel/upper, you would not likely see much flexibility to make any real difference.
If you see barrel deflection under a rail load, it's the upper flexing via the threads the nut is attached to.
You have to ask yourself, what is important to you in the way you use your carbine, and how much difference does it really make? Not everyone runs lasers, not everyone loads a bipod, and will a sling and or a barricade effect you enough in a dynamic environment.
I have tested mine, as well as others, we did great, but yet there are others out there who did great as well.
There is no standardized testing that I know about... so yet another variable ��
DD, Geissele, KAC... I've used them all, and all with good results.
Cheers, Jim Hodge
