New Convert with .25 Marauder Questions

[Harpoon1]

First PCP, trying to get up to speed, learn the lingo, walk the talk!

Getting a new .25 SynRod and need some hand holding.

I would like to throttle it back some, down to 30 FPE or so, for backyard use. Think 30 fpe is enough power and more importantly, want it as quiet as possible. Next on the list is consistency of power and low ES/SD.

So, with that in mind, Im assuming I'll want a regulator, possibly a Huma? Gauge or No-gauge? And a springand/or hammer kit to tune the power? No idea were to begin there! 

Anywhere sell the regulator and spring/hammer kits, for one stop shopping?

Thanks

First of all, good luck with your new rifle.
I also have a 25 synrod. I have read every post on the dark side with Marauder in the title. What I have learned is the very few people regulate 25s. Marauders have 215 cc air tube. A regulated gun requires a small space for the regulated air to feed the valve. This is called the plenum.  If it is too small then the air pressure will drop when the valve is open, resulting in a weak shot. So the regulator, the plenum and the valve use space in the air reservoir.  While this does make the velocity consistent, it also reduces shot count because it reduces air volume in the reservoir.
 Your rifle may work well at 30 fpe. I will be interested to know how this works for you.

Welcome to the M-rod world!

Yep.  Yep, and yep.   I agree.  A regulator is not the best use of space and air. There's not enough advantages to make it worth adding.

To make it quieter there are are a bunch of EASY tweaks, but here are three quick ones.   
1)  back the power off and tune for a lower fps....which you're already going to do. 
2)  open up the vents on the air stripper. (I almost doubled the size of mine) 
3)  back your metering screw completely out of the air flow.  (4-5 turns out from completely closed)
There are many, many threads, on this site and a couple of others, addressing the possibilities and how-to's, but those 3 quick things will get you going down that proverbial rabbit hole.

Good luck and good shooting!

Getting a new .25 SynRod and [...]

I've been here about a month and a half and learned a lot, but I keep seeing these mystery terms.  I get that "Mrod" is the Benjamin Marauder, and "Prod" seems to be the pistol Marauder, but what is "SynRod"?  (I didn't want to clutter the forum with a new topic just for this.)

"Synthetic" stock Marauder.

At least thats what I think it means. And it is what I meant.

Yep, synrod is for a synthetic stock Marauder. This link will prove very useful in the future. There are tons of abbreviations, slang and acronyms.

Thankyou!  Very helpful.

[HunterWhite]

BTW L.D.C. means Lead Dust Collector, to avoid the more recognizable term muffler. Yes synrod = synthetic stock marauder.

Definitely want one of those too. Which one do you have and where can I get one?

There are plenty of regulated .25 Mrods out there.  40/40fpe, 24/50fpe, are pretty good shot counts and within reach.

[HunterWhite]

Do you think 45 shots at 30 fpe is possible?

Jsar I think is where I got my ldc from

Search for Brian's Low Power Tune (BLT) on MarauderAirRifle.com. It gets you 25-30 shot at 800ish fps on a 2500 psi fill, great if you are hand pumping and really quiet.
When I first got mine I set it up this way and had no problem dropping starlings at 65 yards. If you would like to try it I will look for my notes for the settings I used which would get you in the neighborhood.
Also with the .25, you'll find the impact is much louder than the report from the gun.

Great advise.

Being your first PCP, I would not jump into extensive mods right off the bat.  There is allot to learn.  The oem rifle can be tuned to 30fpe for 24 or more shots.  Also, at this lower power, you may find a LDC is not necessary.  Learn the gun, learn about pcps, figure out what you want to do with it exactly, then start down the modification rabbit hole.

Yes the old adage was that regulation wasn't beneficial on the 25 Mrod.  That barrier has been broken.  Regulation can provide benefit in the 25 cal Mrod, especially if your power level is less than 50fpe.  Many have documented that here on GTA.  It does require other mods, include valve and transfer port, hammers and springs.  This becomes another whole level of tuning and learning.  Not recommending you jump into that end of the pool yet.

Thanks dude, didnt know about MarauderAirRifle.com! Good stuff, between MAR.com and Hajimoto's excellent YouTube tutorials, feel like I have a pretty good grip on it now.

Thanks again.
