FX DRS vs Panthera (Dynamic block)

Thank you for posting this, so it’s literally just the different barrel liners they use for everything else? How much did it cost to change barrel length from 700 to 600? Looks like a caliber change of same length would be $400 + mags. Sorry I’m pretty unfamiliar with FX rifles.
Huma air has caliber change kits i think for about 80 bucks plus shipping which i think is pretty steep but that kit a probe and liner would change it to what caliber you want for under 300 i think

There are several parts to consider for Caliber change.
I have just done it on my Panthera.

Huma Caliber conversion is good to start.
If you shoot pellets you will want to add a pellet probe instead of the pin probe.
You will also need as mentioned the liner, and a CF sleeve, and for your shroud you will need a shroud insert as a .22 insert will be a big problem is shooting .30
And for me I like having a second aluminum sleeve so when I change calibers all I have to do is pull the whole barrel out and put the other one in.
Much better than changing all the parts each time.

Oh and the one thing I forgot to ORDER!
New Magazines.

As for longer or shorter barrels figure all the above and also a new shroud.

It can be a bit expensive.
But I can change from 30 cal pellets to 22 slugs now in about 15 minutes.
 
Awhile back I converted my Panthera 22/700 to 30/700 quite easily, then just this week from 30/700 to 30/600 - UA had all parts in stock - rec’d in 3 days.
The parts list / schematics are on FX website under support.
Thought this was interesting, this is from UA when I asked them->

If Utah doesn't want to sell the parts...call Huma.
I bought my DRS because it was advertised as a Dynamic Rifle SYSTEM. To me that meant OPTIONS other than a bigger/smaller plenum and a silly rail. (2 interchangeable part HARDLY constitutes a SYSTEM). We were supposed to have different air tubes (carbon fiber). FX hasn't released anything new for the DRS in 6 months. There is absolutely no reason they cannot sell a barrel kit for these guns.

Set it and forget it..... more like sold it and forgot it.
 
Bagnall and Kirkwood can put a kit together.
