Benjamin 397P Phase 1

[--ped--]

you don't see many of those eb stocks in the UK
there was a lot of new/old stock ones on the bay a few years back in the US but shipping was a bit pricey i thought

I remember them for a short period in the old airgun magazine adverts. I ordered some parts from the US and combined the shipping.



The parcel included a new plastic sheridan hand guard. Which makes the pumping a bit easier on your hand stops the finish wearing off.

Another nice sunny day for a few shots on my now favourite carbine. The trigger pull is still very clunky and heavy and unlike the 13xx and 22xx there's not a lot you can do about it. I was having so much fun I forgot to chronograph it.

I recently collected this Benjamin AS392 with an empty 88 gram canister still attached. I didn't bother trying it with a fresh 88gram as I wanted to use the more economical 12 gram co2 via an adaptor.

Without test firing I went straight ahead with stripping it down for a clean and new seals, everything was there except the end plug with a grommet in it's place. As the cylinder is redundant it didn't matter other than looking unfinished and luckily I had held on to a spare. The valve and adaptor screw was chewed up, so I replaced it with one from Chambers.

The hammer strike on dry firing felt very weak, there wasn't any old grease slowing it down but It had improved with polishing the striker and stretching the main spring.

I got all the parts clean with Isopropyl and fitted new seals with silicon grease.

Once again Ped helped me out with an obsolete seal and supplied the ones prone to damage in Polyurethane. There were 12 seals in all including the one on the valve stem and adaptor.

I used the best fittings co2 adaptor as this has an updated design using an oring around the bulb nose instead of the sealing face. I never had much luck with the original type but this may have been due to the poor quality supplied seals.These adaptors can be bought cheaper on from China but best fitting's have alway's been a good company to deal with.

I've mounted a bugbuster 3-9x32 ready for testing the accuracy at short range. It's a good solid rifle thats much more sturdy than the Ratcatcher and just as easy to work on.

the Buccaneer is one of the best co2 rifles in the the crosman benjamin stable
on mine i always alter the trigger so i can decock them along with bonding the pins into one side of the trigger unit
i also fit an adjuster so i can take up trigger slag and weaken the sear spring
i'm just in the process of making a regulated air tank for one

Great idea, I like being able to de-cock. I think Crosman changed it for safety/liability. With the older stuff you can. I haven't found the trigger to be too bad, the double sear for dual power is a good idea.
I'd like to see one with a regulated bottle!

I spent some time trying to improve the bad EB20 trigger by smoothing out rough spots, greasing, shimming and adding a trigger shoe. The trigger shoe is a really nice addition, which I got about 10 years ago from SD custom designs, Steve Darrel? The trigger is still bad but feels nicer to shoot.
I shot it over the chrono it was quite cold this morning but still produced 5fpe. I'll add a hammer spring guide and check the power. The .22 version must sit very close to the limit.
