My new P-Rod arrived today, sure do like it!

Man, this Benjamin Marauder Air Pistol is NICE!. Slapped on a 3-9x40 Hawke Vantage AO scope. I tool the scope off one of my other air rifle to see how I liked in on the p-rod. I liked it just fine. To check zero, I shot it at a 10-yard target and the pellet hit an inch to the left of the red bullseye on the splatter target. Then I shifted to a 25-yard target and zeroed it in. Time and time again, I put pellets in the red bullseye, sometimes holes touching.

I was shooting a 14.3 gr pellet and will try a lighter pellet tomorrow. I wonder if lighter is the way to go with a p-rod?

I understand that they don't make a .177 p-rod, I wish they did - did they ever make one in the "old" days?

It doesn't seem very loud to me, so I may or may not look into a DonnyFL silencer for it, maybe a TANTO.
 
Still have 2 of them — one was my 1st Airgun! My favorite Airgun to this day is a carbine .22 due to the influence of my fully-modded Critter Getter! To this day I still love to shoot a Prod and yes, the Polymags are awesome—-love the noise they make when popping a squirrel!! Next was a 25 Marauder but the Prods get shot more than anything I own to this day! They are awesome for beginners and kids when you don’t want your Daystate or FX scratched up. My original Prod shoots most every pellet well and kids (supervised) love to shoot it as it is not a heavyweight. Also mouse-fart quiet with an extremely inexpensive moderator(TKO).
 
If you can live with single loading? The 1720T is a 177 p rod without a magazine. It's tac driver with its LW barrel. Iv been through many a rifle. But have never considered getting rid of the 1720T.

I have a pair of them, one is day rig over five years old with Tim Hill insides and his LDC very quiet and snappy . The other is a factory stock night shift rig with a sight mark IR scope. Both have worked out as a great deal for a sub $400 priced pcp that can be customized to transport it's owner to nirvana and targets to that Big Sleep.💀

Congrats on your new p-rod! Awesome pistols!!

Love both of my P-rods. Roy at Mountain Custom made a LW barrel for one of mine. Tightened up the groups even further. I slapped a Tatsu on one and a tanto on another. The tatsu is great for sound ( pistol is power tuned) but needs removal to remove the fill cap. The tanto with the cone cap does not have that problem, not as quiet for power tune but does great on the stock config. Tim Hill makes great moderators as well and no clearance issues. I love his rifle version. 

Hill parts kits are amazing in any Marauder. Highly recommend IF you want to go the mod route but the P-rod is a damm fine gun out of the box. 

Polymags are my go to for hunting with a P-rod. Metalmags are a close second, same with Hornets , but Ive had some Hornets that pinch/dislodge the breech o-ring when mag fed. For bench it loves JSB exacts 15’s. 

Enjoy your new friend! 
 
Congratulations on your Prod. Mine likes Crosman 14.3 domed and hollow points fine and that's mostly what I shoot because they are nice and cheap. It seems to shoot a little smaller groups with less fliers with H&N FTT copper plated. It also shoots H&N Barracudas well but the trajectory is loopier so I stay with the 14+grain pellets. I get good groups with metal mags too.

I made my own stock for this gun. It is just a piece of 7/8 OD aluminum tubing with a 5/16 fine thread bolt sticking out of one end to mate to the gun and with a 1/4 coarse thread t-nut in the other end to attach a butt pad. Works better than the stock it came with and lighter too.

Mine is tuned to about 750 fps and sighted in at 30 yards, the maximum to get a rise no more than 1/4 inch at shorter ranges. That lets me pretty much ignore the distance for backyard shots. On targets at 25 I hold a little low - like 1/4 inch. I can get to about 800 fps but the shot count falls off quickly. My 700 fps+ tune gives me about 20 full power shots. I am waiting on a debounce kit I hope will improve that.

I really like the trigger on my Prod. It is adjustable but so good out of the box I haven't messed with it.

I just sold my prod, a sick p70 with part no longer available parts made for a large bill with my tuner/machinist. They are awesome guns and extremely versatile. The new owner hasn’t picked this one up yet so it got in a little pigeon control this morning. It doesn’t always wear the huge fart can but when it does it is about as backyard friendly as you can get. ;)

My first and only pcp (for now). Shooting smaller than dime size groups with JSB 14.35 and H&N FTT 14.66 at 32 yards zero. Shoots walmart CPHP well enough to be my general backyard plinking pellet of choice. No internal mods but did tune 3 3/4 turn clockwise from full counter clockwise hammer spring preload for max power for 3 magazines at average of 675fps. You can even tune it for 60 shots at average of 550fps before fill. Great little gun for sure. 
 
I was a bit late to the Prod party, as I am usually pretty far behind the trends... But here is one I am working on. The tune is 95% done so it's time to start working on aesthetics. As is, she is an ugly duckling to say the least. 36" long and almost silent with a Tanto mounted. Note by using Donnyfl's tapered end cap fills are possible without removing the moderator.

31" long without the Tanto and still quiet enough to not disturb neighbors.

Here is a target of 5 mags of CHP's, tune is 4 mags @750fps, shot from a 3000psi starting pressure. The last mag was shot at the center bull, well below reg setting. Distance is 40 yards. it will shoot much tighter groups than this with 5.54 diameter FTT's, but that's not necessarily the point of sharing this target. I am just tickled to finally have a barrel that will decently shoot cheap ammo such as CHP's.

It is regulated with a Huma set at ~90 bar, using the larger Discovery plenum. Valve has been heavily modified with a .240 OD peek poppet on a 2mm stem, with a Cobra chamber. Transfer port drilled to .155. Hammer is solid peek, weighs in at a whopping 9.5 grams including the pin. Valve/hammer system is largely my interpretation of methods shared by Motorhead/Scott over the years. Cocking effort is very similar to OEM. The barely-there peek poppet is pretty easy to open. I used a Gen 1 Mrod trigger (with shim) and mounted the action in an old QB stock.

These mods make for a very quiet, snappy shot cycle with zero vibration from the hammer strike. Pretty miserly in the air consumption department as well.

I am working on a .177 version of basically the same tuning package, but it is mounted in a second gen Rapid-70 Bullpup kit.
 
Here is my Rapid-70 in 1720 form. Hopefully I can pull off the .177 Mrod magazine conversion. Worst case, it just stays single shot. Those 1720 barrels are tack drivers out to 40 yards or so. Currently regulated and tuned for 45 shots of Crosman 10.5's @ 725fps Virtually silent with the Tanto on the muzzle, which doubles as hand protection for such a short gun. I'm sure someone is likely to put a pellet through a finger at some point in time and I hope it isn't me!
