p-rod barrel

[pyroboy33]

I was wondering if any of you fine folks know where I could purchase a drop in full length barrel for my p-rod. I know the m-rod uses crossmans factory 7/16" diameter barrel but I am not sure about the p-rod, Jim Gaska sells the drop in l&w barrel but I am itching for a rifle-length barrel verses a 12" pistol size. I know that the barrel must be machined to accomodate the p-rods shrouds and what not but I'm just  curious, any input is welcome

I read some wear of someone selling a prod with an mrod barrel installed. That would be the least expensive option if it is just a drop in swap.

I'm a little confused here.  If it's a full length rifle barrel, why worry about the P-Rod issue shroud that's not going to work on it anyway?

Jim gaska sells custom p-rod shrouds that can be cut to any desired length. Thinking it over now I might just buy a .22 m-rod barrel send it to JG for machining, then order the custom shroud (also from JG).

OK, that makes sense.

Believe M-rod barrels are an easier fit to P-Rods (at least the issue .177 and .22 barrels are, haven’t worked with a .25 which I believe is a bit fatter).  That and a full length P-Rod diameter should work.

Jim machines the rear and the front on the drop in LW P-Rod replacement barrel, but leaves the middle section “fat”. Can get the issue shroud parts to work this way, and he keeps the cost down this way (although his  shroud extention is certainly worth the p5rice of admission).

Muzzle to the left/breech end to the right (gold tint the product of indoor lighting):

So I'm guessing the transfer port is under the right side where I cant see?

[Rescue35]

A factory .177 or .22 Mrod barrel will fit a Prod. The only thing I didn't check was the transfer port location on the Prod as I am not up for tearing mine down at the moment.

[Ribbonstone]

Yes…on the other side.

Well cut (and with a flash, no gold tint):


Clean and burr-free on the inside:


Suspect some of this will seem odd.



LW barrel shots great, but had an occasional “twich shot” that I suspected was NOT my fault.

Got a bit better OVERALL accuracy  (losing the “twich shots”) when the shroud was “dampened” to the barrel. Figured that the barrel vibrations and shround vibrations could be damped out a bit by using some o-rings (with a bit of tape ahead and behind them to keep them from sliding).  For me, it worked for a bit better overall accuracy.



Have had it up to +20 foot pounds, but wasn’t real happy with the shot count. Down tuned the P-rod to about 12 foot pounds.  Know that goes against the grain of most P-Rod buyers, but for everything I use the gun for (including squirrel hunting) it’s worked out great.




Also tossed the problematic magazine and made a single shot tray.  Suspect the good magazine is still someplace in the shop, but I’ve not seen or used it in a year.


Got talked out of the Al. shot tray and had to make another.  To do that, dug out the problem magazine, opened it, filled it with epoxy, put it back together (minus spring), cut off the bottom section, and shaped it into a single shot tray. Nice thing here is that it slides in and out just like the magazine (and i hope Crosman is listening here...they could make a part like this for next to nothing).




So not what most people do with their P-Rod, but that’s kin of the point (and the point of you wanting a rifle barrel):

They can be what you want them to be.

That sure is a sweet lookin p-rod, I really like that cheek riser looks like it came from the factory like that. My p-rod is pushing 14.3 cphp's at about 745 fps average for 2 mags or 16 good solid shots. The main reason for wanting the rifle barrel is partly for the small velocity increase (without losing shots it is basically tax free  ) and also for the increase in longer range accuracy that a 12" barrel just cant provide. Also imo my p-rod coupled with a m-rod barrel and one of the new double tube kits from lloyd will make a mean little carbine tuned to around 24 fpe for 2 mags, but that's just my opinion. Btw do you guys know how much the m-rod .22 barrel costs from crossman and what the part # is?? thanks 

[Ribbonstone]

Cheep riser: two lengths of Al rod, a shaped and painted length of wooden dowel, 4 blind holes, put together with a bit of epoxy. Only "tick" is getting the blind holes (1) in the right spot and (2) vertical (careful use of a tape measure and a level would take care of that).
 Have not ordered an M-Rod barrel, so no idea of the cost...other than typical Crosman-reasonable compared to any other airgun replacement barrel.

As a pump filler, haven't made up my mind about the double tube versions.  More shots, but figure the number of pump-strokes to refill per shot would be about the same.  Cranked up, if I needed 40 strokes for 12 shots or 80 strokes for 24 shots wouldn't make much difference to me at the end of a day's shooting.

hey-Hey!!!,
The barrel length will get about a 15 fps increase per additional inch of length. I put a 24" barrel on my Mrod and got about 50 fps more with the same air. Sounds like a fine project.

IMHO I think you should get an Mrod 25 and live the good life.

Bob, it *IS* difficult to put out a fire with gasoline you know...

Haha I wish  , but right now a Thompson/Center Venture .223 is on the top of my purchase list 

[bnowlin]

Good gun I hope it works out for you.
