Joe, im going to tell you right now your logic is majorly flawed. There is no exact science in CA's. Thankfully, the stock compression is getting more and more consistent. From my experience: I have put a CA170%(like a m120) spring in many a M15A4 rifle. Some get only 340 fps. Then I change the bucking and it gets 360. Then I take the whole thing apart and relube all seals in the top end and bam, 400. And then on others i do that same process and only get 380. THEN there are ones then shoot 410 the moment a spring is swapped. Get the picture?

The TM G36 and CA G36K, we have, that Andew has maintained and modified using the usual procedures and anything else he does, has worked out great! In fact, neither one of our G36 (TM or not) has failed in the area of FPS. We've had them for almost 2 years now and they still run at approximately 390 + FPS! The TM one runs around 350, because it has recently been upgraded for CQB/CQC environments (sorry for not listing what parts he used), but A would know.
