sscoyote: Hey XO--how do you open the transfer ports? I saw you mentioned a dremel
tool. What bit size are you using? And at what angle?
Terry Koss: I'm a newbie to the air pistol. I'm just about to pull the trigger (sorry)
and buy the Marauder. Point being, though you've explained how to modify
it, I'm still lost. It'd be great if you made a step-by-step vid on the
mods you did...including the porting you mentioned in a comment a year ago
(where you state you're getting 1100 fps with the 14.3gr pellet). I'd like
to know what the slugs fps are with all your mods.
bwnj42: fps,,,,is one thing wheres the most important thing ACCURACY
Eric A: Can you please share what mods you have added to achieve this FPS? I Know
you opened your transfer ports, but to what diameter? Also what hammer
spring are you using? And is there anything else or just tuning the pistol
to max power/less shot count?
Xxoo0o0o0ooxX: @shield400 Vinyl tube? I don't see why not give it a try & see what
happens. I would love to know if drilling holes would help the sound.
miketheknife2: very nice now how was it done.so when i get mine i know what to do.
Xxoo0o0o0ooxX: @spr00sem00se I have been shooting with the stock spring last few mouths it
requires less pumping that way. It still has more power then most if not
all spring .22 rifles.
Xxoo0o0o0ooxX: To port the air from the valve to the barrel. There will be a blue metal
port that you replace with poly tube of the same size. Remove all rubber
seals as well.
Xxoo0o0o0ooxX: The poly tubing you need is OD 14"x.170" ID
Xxoo0o0o0ooxX: @xavierblaq It is very easy to do your self. Order a stronger 2240 hammer
spring. Then replace transfer tube with poly tubing that is used for
refrigerator ice maker line.
CHANMIandDAVID: what size is the poly tubing? and all you do is take a piece of tubing and
replace the factory port? or do you have to do other things
I'm Simon: Great power & you obviously know what you're doing around air guns. That
said, I look at the gauge at around 2000 psi after just a few shots & I'm
thinking I would have to be pumping the gun up again already. I like to
shoot a lot of pellets; I guess PCP guns are just not in my immediate
future. The little CO2 bottles cost me around fifty cents each (when buying
40 at a clip). The pellets (Crosman Premier Hollow Points cost about 1.5
cents each; so at about 50 shots each bottle 2.5 cents per.
Greggg57: I want something quiet and strong enough to kill a Turkey. It needs to be
at least as powerful as a 22 short. I have a Whisper pellet gun and am not
a good enough shot to do a head shot and anywhere else doesn't even phase
those big birds.
Airat: What external diameter Quick Disocnnect Male Nipple in a working part?
MischievousIQ: @shield400 I don't think he actually knows...judging from his previous
replies it sounds like he had some spare springs lying around, stuck one in
and got lucky. which is probably why he doesn't go into details about it.
check the different airgun forums you'll find more details and help...not
just someone showing it off.
Xxoo0o0o0ooxX: @shipyardbob My new goal is to get 50 foot pounds out of this pistol. Great
gun nice to see air pistols catching up with firearms.
Xxoo0o0o0ooxX: @zen260 Thank you :-) There are a lot of dumb laws I am sorry to hear about
sorstudios: That's a good dream. Only bad thing about the TalonP is the recoil and
Xxoo0o0o0ooxX: The only mods done to this pistol shown in the video here are. Poly tubing
transfer port seal & stronger hammer spring thats it. I since bored out &
ported the valve. I also bored out the barrel port to the same ID of the
poly tubing. She now does 1100 FPS with 14.3gr CPHP pellets.
EliteAmericans: LOLZ that thing is powerfull enough to kill a large dog without needing a
Xxoo0o0o0ooxX: Yes she agrees with you. She will make a point to stop anyone from having
fun. Huh? Interesting kinda like a women??
Xxoo0o0o0ooxX: I have been waiting & waiting almost gave up on after market parts. BTW cat
sitting on lap says hi also :-) I started modifying my pistol way before
anything else was heard of. I know you have a rifle stock now but have you
rested your gun on a bench or even some pillows? Because I still am
impressed how accurate this gun is. Even fully decked out 10/22 targets
cant out perform this gun with it's short barrel. Your stock barrel is
chocked just like the Walther.
Xxoo0o0o0ooxX: @spr00sem00se 16 full power shots at 3000 PSI 24 full power shots at 3600
PSI Can shot pellets thew pellet holes. Stock you get 3-4 pellet clips at
EliteAmericans: 25 fl pounds is basicly the same as a CB short round. But if that's going
985 fps it will have a longer range than the cb shorts (29 g 700fps)
phantomshtter: You need a Discovery rifle then or the Maurader rifle. Not this.
lee ewa: How did you modify it ?
Andy J: Shoot the cat with a hollow point, now that would rock.
DressUpYourPet2: Beretta the cat wants to see what you are paying so much attention to that
Bannanaslicer: "You gotta move" "Meow!!!" LOL
Xxoo0o0o0ooxX: Not out of a pistol.
Xxoo0o0o0ooxX: @Lyecdevf Good very powerful pistol. It will out perform your Gamo rifle.
But to keep things silent stay under 700 FPS with this pistol.
Xxoo0o0o0ooxX: @EliteAmericans Easily I got rid of that red/green dot scope & ordered a
2-7x32mm Pistol scope with a 20 inch eye relief.
Hepotter: Please tell me 220Swift still makes those air tube extensions, and is it
your or Swift making the extended shroud and baffle? I love tricking out
the Prods. They make a wonderful little carbine and have power to spare.
Can't wait for a .25 caliber. Anyway, can I obtain that extended air
cylinder, long shroud/baffle at this time? I would appreciate any help.
Ray Klefstad: How is the accuracy of your Marauder pistol with this power upgrade? I'd
really like to hear that you get 8 shots in a single hole at 30 yards - at
least with some pellet. My 25 Marauder rifle gets 8 pellets in a single
hole to 50 yards, but my Marauder pistol was spraying pellets all over the
place, so I sent it in for warrantee repair. I'm still hoping they can sort
it all out as I really like the basics of the Marauder pistol.
Xxoo0o0o0ooxX: @romancetech The power shown in the video is nothing now. All I did before
was stronger hammer spring & poly tubing. When you dremel the valve port &
barrel add polly tubing transfer port along with a stronger hammer
spring....... 1100 FPS with 14.3gr pellets! Best part you get 16 good
shots. If tuned lower you get 1000 FPS with 24 good shots!
Greggg57: Ok. Thanks. I will try some CPHPs.
Xxoo0o0o0ooxX: @1942nuclear I never got to see the internals of the P-23 but most airguns
are under powered. So I could see it being done :-)
shield400: Is that a single shot adapter in your Marauder, where did you get it?
Looking forward to your extended brass safety video. \m/
Chuck Asher: I understand all of the other mods but I am confused about how the poly
tubing is used. What do you do with it? I'd really appreciate the advice.
Thanks, Chuck Asher
Xxoo0o0o0ooxX: @TheJohnnyairgun Say what??
Xxoo0o0o0ooxX: Yup thats with just a stronger hammer spring & poly tubing. I then opened
up the valve angled the transfer port.Transfer port on barrel also opened
up. Then it was shooting 1100 FPS with a 14.3 pellet & 664 FPS with a 40gr
pellet. I was only getting 8 shots out of it with a rainbow shot curve. I
installed the O-ring buffer mod & was getting 1000 FPS with a 14.3 gr
pellet with 16 shots & a flat shot curve. I can turn it down & get 5 mags
out of it at 550 FPS with 14.3 gr pellet so silent on low.
sorstudios: So you just put in a new valve? And where did you get it?
Xxoo0o0o0ooxX: The only mods I have done to my P-rod are valve port, poly tubing, barrel
intake port, hammer spring. Every thing else is stock! Including the 12inch
barrel. If you tune it down a bit you get 2 mags of 1000-950 FPS Otherwise
about 14 shots at 1100.
Xxoo0o0o0ooxX: No, this mod is just poly tubing and a harder spring. After valve work, it
does 1100 fps with a 14.3 gr pellet
sorstudios: After valve work what size valve .118 ?
Xxoo0o0o0ooxX: Yes I got it tune how I like it now I get two 8 shot mags out of it now.
But yes you will be pumping a lot. It is good for you but I know how you
feel. I picked up a supercharger pistol that breaks open for fast reloads.
But otherwise get a rifle that can hold lots of shots.
romancetech: your claiming to modify the gun but you never claim what you did and your
always shooting roosteried across the chrony if your not going straight thru
the field you will always get a faulse reading if your getting this kind of
power thats great but your not really showing anything most stock guns can
be adjusted to the same levels as you are showing so what exactly is your
mod turning screws or what ?
Xxoo0o0o0ooxX: @dt45acp Yes the Mrod pistols have a regulator this is very cool keeps the
Xxoo0o0o0ooxX: @ckddudaos5 Does 1100 FPS now with lead.
Xxoo0o0o0ooxX: I does 700 FPS now with the 30gr pellets. But the big advantages are it is
quiet & low cost to shoot. Also there is just so many pellets to choose
EMT: Thanks! They sometimes skip corners and take the easy way. If they ever did that, I suggest you consult with a paralegal or lawyer. This way they won't be able to cheat you.
