P-rod in .177? Who has done it?

[JMJ in NC]

I was thinking of getting a P-rod and converting it to .177. This will be for my son, swapping parts from his 1377-based target gun onto the P-rod so he will have a PCP.



Just wondering who has done it already or if there’s an easier path to convert the MSP to PCP. Maybe using a Discovery lower assembly?

Multi-shot capability is not critical.

Thx. JMJinNC

If you can just pick up a 1720t. I have had a few and they are incredibly accurate.

With that configuration, all you need is a Disco tube, probably a shortened one, and its parts.

How long is that barrel?

[JMJ in NC]

19” LW.

I'm pretty sure you are capable of reducing the tube length yourself, Mr. John.

Mine is a low power Disco/2260 with a .038 MAP hammer spring and a Challenger transfer port.

Baker Airguns has that tube if Crosman does not have them in stock.

Great info. Thx!

Yes, that one too, but they are now very expensive and not even available.

I have one, a 1720T with a 10" 1701P barrel.

There were no 1720T barrels when I built it, so I went for the shorter barrel.

Again, mine is set up for short range, about 25 to 28 yards, so it's a low power build.

It has a .038" MAP hammer spring and a red transfer port, the smallest.

With a PROD shroud,  it's very quiet even w/o a "can".

It likes JSBs and AAs, but is even better with H & N FTT 4.52 pellets.

After months of not shooting anything, I shot it today and was so impressed, as it was drilling the same spot with the aforesaid H & N.

I like my Don Cothran stainless builds, but the 17xx platform feels much sleeker and is so much easier to load.

Built a few Prods from parts.
Both are great guns.

The 17 cal uses a 9 ci bottle.

The 22 cal has a Huma regulator, recently added a 500 mm FX barrel liner.

Can also mod your 13xx.

As mentioned, using a shorty disco tube would allow you to use most of the 13xx parts.
With that said, I really like the multi shot function of the Prod breech.

Might get more response in the PCP section.
