I was looking at Jim maccarris Beeman r9 kits and found two, one was the Hornet MK6 kit and the other was the High power special order kit?. Has any one here installed this kits in a home tune? and what was the genaral impresion after installation as to power out put and accuaracy improvemen with each kit?.
I might go Vortek but still searching for options.

And go Maccari on one, Vortek on the other. Keep the one you like best, and sell the other to me at half price.

Deal? =P

Devin, Just kiding ( LOL ).
This will be my third R9 well lets say forth if I count the B26 I had. One was tuned the others three were not. They were all great shooters but the tuned one was a killer all the way. All my other hws are tuned,beeman R1 .20 cal and my Hw80 .22 cal great shoters too. I just want a nother R9 tuned, just to make me happy.But this time I want to drop the kit in my self.

JMO, but none of these kits will make any accuracy difference, provided they are all compared at the same power level in the same gun.

If it was my gun, and i was leaning toward a Maccari kit, I'd shoot the gun until it was well broken in. If it developes above average power in stock form it will probably benefit from the Tarantula kit.

When I tune an R-9, I prefer the Tarantual Spring. However I build my own kits and i get exactly what i want for each particular gun.

The VORTEK kit is a pretty elegant solution also, especially if you don't have experience building kits.

And supposedly gone for good.

The Hornet Kit or spring is current choice for R9 and similar applications--it works quite well with as good velocity as the old Tarantula if the piston seal is right. Of course 33 coils of the T spring would allow for max spacing-max power and fit shorter pistons, while minimum spacing was good for FT applications, etc. But, gone is gone except for private stock.

There are still other JM spring options for FT-type applications in the same rifles.


Happy Shooting!

......I haven't been over to JM's site in a while.

At least he has a high power kit based on the Tarantula Spring still.

Too bad, it was a damn good spring. Good thing I have a nice stash of them!

How close is this 32 coil Euro Tarantula compared to the original Tarantula spring?

so I'm guessing that the "NEW" spring with .128 wire wound in a .512 nom ID would be a bit "stiffer" and more highly stressed.

Of course the metallurgy has an affect on this and I have no clue if the wire is the same...probably not.

That is one of two rifles I currently regret selling. It was a real treat. JM kits are very robust you get a definite feeling of longevity & craftsmanship.
