I found a few remaining Titanium flash suppressors misplaced on the wrong shelf – after these are gone there will be no more – cost on titanium has gone thru the roof to the point that my cost today to fabricate new ones, would nearly equal what these are retailing for.
I have some for the HK MK23 (16X1MM Right hand threads), HK USP Tactical 40 (14.5X1MM Left hand) and the USP 9MM SD (13X1mm Left Hand threads) – price is $149.95.
The CCF Accurizer / Flash suppressor were originally designed for us overseas in late 1995 by a retired engineer from HK Oberndorf, for use with the HK MK23 SOCOM 45 pistol. In our Initial testing, with light intensifier night vision equipment we measured a flash signature reduction of 80% on the MK23 with muzzle flip reduced to virtually zero, making the MK23 as tame to operate as a sewing machine, and making second shot target acquisition a total non-event. We made some for the HK Tactical 45 and found the same flash reduction but muzzle flip on the Tactical was reduced 50% (measured with a high speed camera) - bear in mind the Tactical 45's natural muzzle flip is more than twice that of the MK23 due to it's lighter mass.
In December of 1999, after having received a number of user reports that their accurizer / flash suppressor tightened their groups, we tested both the MK23 and Tactical 45 on a Ranson Rest and measured groups tightening by 30 - 35%. Bear in mind, both of these pistols are already known for tight groups due to HK’s O ring bushing system.
This was a benefit we definitely were not expecting to find, but, looking back on it, up to 1999 we must have gotten a hundred + calls from customers indicating their groups had tightened when they started using the flash suppressor. It was definitely nice to hear, but, not knowing the source, we were unsure how much value to give those statements. When we heard from two different ranking IPSC shooters indicating their groups had gone from 1.50" down to 1.00" at the 25 yard line, we decided to investigate, firing groups from a Ranson Rest at both the 15 and 25 yard lines with and without the flash suppressor . Our customers' reports were definitely confirmed. The explanation for the accuracy enhancement has to be the flash suppressor eliminating "dirty air" from being created ahead of the bullet by preventing the expansion gas from getting out in front of the bullet. If you watch a slow motion video of a bullet leaving a barrel you will notice for the first couple of inches out a barrel, the expansion gases actually speed forward past the bullet. We surmised that either one or both of the following two scenarios were taking place - 1st, expansion gases were creating dirty air ahead of the bullet or 2nd, as the expansion gases break past the rear edge of the bullet's base, they torque the bullet and give it a yaw and destabilizing it. When you have the flash suppressor on the barrel, while the bullet is in the flash suppressor, the expansion gases are channeled or vortexed off to the side where they can't torque the bullet and by the time the bullet has exited the flash suppressor, whatever expansion gas remains behind the bullet has lost most of its energy (gas having very little mass dissipates its energy quickly). If you're looking to print 1" groups at 25yds with your Tactical 45 then this is the ticket.
MORE ENERGY ON TARGET WITHOUT INCREASING YOUR POWDER LOAD!!!
We have only confirmed this by elimination, but on the chronograph, we measured a 40 - 42 fps increase in velocity with Winchester 230 gr RN "USA" ammo. This increase in velocity can only be from the elimination of the dirty air in front of the slug as we know dirty air robs energy and velocity.
Doing the math of energy = mass X velocity divided by 2 squared, a 5% increase in velocity means an 11% increase in energy on target. While that may not be that critical to a 45 as it's already carrying sufficient energy, to a 9MM 124 gr slug, 11% is a lot more energy to have. Even more interesting, if the velocity of a 230 gr slug increases by 5%, the velocity of a 115 or 124 gr has to increase even more as dirty air would be robbing more velocity from a lighter mass bullet. We haven't choreographed it yet, but if velocity enhancement on a 124 grain 9MM bullet is to the order of 7-8%, that will mean about a 15-16% increase in energy on target from the same bullet WITHOUT AN INCREASE CHAMBER PRESSURE!! Basically, a standard 115 gr 9MM round goes to +P velocity and energy rating, a +P goes to +P+ energy delivery, etc and all without increasing chamber pressure.
