I have a JP LRP-07 and even with the adjustable gas block you will want a can that minimizes the back pressure. The tight tolerances in the JP won't like a lot of gas being blown back into the gun....the AAC and LRP are a great mix....no real affects on accuracy once you zero with the can on the gun. The combo works for me....you can squeeze a tiny bit more long range accuracy out with the cyclone. </div></div>
Maybe dumb question but how do you determine how much back pressure one can will have vs another? Or if the adjustable gas block is able to compensate?
I contacted TBAC about the possibility of a demo 30P </div></div>
The term "additional back pressure" is somewhat of a misnomer. The pressure will not increase in the bore due to a suppressor being on the end of the rifle.
Without going into it, the suppressor mimics a longer barrel using the same gas system. The ability of the suppressor to work within the parameters of the rifle gas system is determined by its pressure curve on a given barrel length.
The suppressor is basically increasing the duration of the high pressure gas at the barrel gas port. It does not increase the pressure. What you get as a result is an increased gas impulse acting on the piston. You then are looking at an action that may open earlier or have increased bolt speed. If the action opens early enough before the pressure in the chamber has dropped, you may experience difficult extraction or gas exiting through the chamber.
Our BREVIS 7.62 compact suppressor works well in actions where some suppressors do not, but any design you choose will be a compromise. The key is choosing a suppressor based on a needs basis. If you have the option to use one of the JP adjustable gas blocks with your rifle, it can go a long way toward making the suppressor you choose compatible for the platform.
I might suggest listing everything you would like the suppressor to do, then weight these goals. This will give you the ability to choose between the different designs and their differing performance.
Hope that helps. Best of luck with your project. And always, shooting the suppressors on your short list is best if possible!
