Team,
I am glad to see that the Old Marauder is still of interest and desire. The M-Mod has stood the test of time like a Timex, takes a licking and keeps on ticking. I have several M-Rods ranging from tuned stock to extreme mods, they all have a specific purpose. I must agree with the information in this string, you can't properly tune a rig without a chrono, you can't safely do ANY work on a air rifle without knowing the dangers. Not releasing compressed air is like playing with a 3000+psi bomb that could result in an UNWANTED event. Please learn your equipment before trying to tune it. This forum is an endless source of information and ideas, you just have to ask the right question. "How do I ???" just ask. There are MANY members who have set person records that are hard to believe, but are true. I still find myself surprised by new small gains rather in ammo, ammo prepping, or even barrel cleaning. I feel that I have reached the end of my mods and tunes; I am very happy with my Beast collection. Accurate and Powerful, Purpose Built. Have Fun and be SAFE.
