Let me be the first to say that RRA builds a quality product. I carry an Entry Tactical as my duty rifle everyday. It has never failed me, the only failures I have had are those that I induced during training.
I also have a factory RRA sbr as well as a Colt 6933, Noveske Diplomat, and Larue OBR Lite sbr. I would not hesitate for a minute to use my RRA sbr on duty and trust my life to it. It works and takes all the abuse I can dish out to it.
I will tell you that the new SWR Specwar Suppressor is showing some pretty awesome specs. SWR is claiming to have specs of 135db with a 10.5 barrel and 133bd out of a 14.5" barrel. Quick attach method and includes the mount for 700.00! Length is 7.2" long, 1.5" diameter, and weights 19 oz. The weight of the Specwar is close to the SS phantom at 20 oz. The 308 Phantom ss phantom is 28 oz.
The titanium suppressors have shooting restrictions, last time I spoke to YHM it was 2 mags on full auto then let cool to touch. It should not be a problem on a semi sbr.
I do have a Specwar on order as I want to compare it to my M4-2000. (M4-2K seems to set the standard) Since the M4 2k is right at 1k (can be had cheaper) and the specwar is 700.00, I really hoping it works out. I also ordered it with the muzzle break to keep the erosion down as its going to be primarily on my sbr's.
