CMMG vs High Desert Dog vs Tros

Honestly I think I could. You see my barrel was 10.5 that I put on my ps90, and I had to choose what to leave on it (p90 FH, or suppressor adapter) due to the spring loaded barrel. In having both muzzle devices I have to in set the barrel to switch them out. In doing so-- the barrel is simply ready to slide out of the upper. I like the idea of switching them out, as there really is a performance issue in the 5.7 round with the barrel going from 16 to 10. I also have explored the idea of threading the longer barrel to accept a suppressor. The Sbr ps90 is awesome and I really enjoy it, don't get me wrong. For example with the long vs short barel- 5.7x28 197 will pierce soft body armour, where as with the short barrel it won't, as a result of the decreased velocity (knowing I wiill get comments here and request to post- my source: has been YouTube videos - realizing and accepting claims for aunthencity) even withy he argument that it does not-- there is a big drop in velocity from one barel to the other. One other thing. My Sbr barrel is 1:9, where as stock is 1:7. Knowing this- we know that a 1:7 twist will perform differently than a 1:9.

HDD did my barrel in 07 and it is a great shooter. I can't call it a tack driver because no PS90 in either flavor is really a "tack driver". Other members have had dealings with HDD recently and some have had difficulties.

TROS is an option and I have bought a couple of adapters from him and his products are fine. I can not speak for the SBR though, although many members like the work that he does.

Stryker is releasing a short barrel for the PS90 and if like his other items, it will be worth the wait while he gets this product off the ground.

CMMG did a bunch of barrels then left the market. They decided to come back into the market not long ago. I have one of their newer barrels but am not sure what to do with it considering the adapter I got for it is not concentric (according to them) and they sent me an email indicating that they will replace the faulty adapter soon. I am still waiting, though they indicated replacement sometimes in Feb. I have concerns that it may be the threading of the barrel as well as the threading of the adapter that is causing the baffle strikes in silencers that have been reported. The only way to be sure (for me at least due to testing equipment constraints) is to wait for the new adapter and mount the barrel and if there are other reports of baffle strikes, then it is the threading on the barrel that is the problem. Don't know if I want to sacrifice one of my cans to try this option though. I have to admit that CMMG when they finally admitted to this problem, has been working to solve it and they did not report that there was any problems with the barrels. BTW, the adapter in question is the 1/2X28 TPI one.

These are the options that I know about. Of the four mentioned above, only Stryker is a forum vendor at this time.
