I actually recently purchased the Factor RC, from Krale in the Netherlands. With shipping, it ended up $1063 USD to my address in MI. I ordered it on a Tuesday evening and it arrived that Friday before noon.
I’ve had it for a few weeks now, around 400 rds and the barrel is getting nice- hole-in-hole @ 30 yds with a BOG Death Grip tripod set to standing position, with or without suppressor (suppressor needs 2 minute scope elevation adjustment over non-suppressed, no windage needed- DonnyFL Sumo). At 30 yds, poi is same with transfer port set medium or high, it starts changing farther out, but I keep it medium most of the time since I’m usually just shooting paper or chipmunks.
BTW- as it already has a fully-shrouded barrel, it’s not very noisy at all, but by adding the DonnyFL Sumo, all I can really make out clearly at this point is hammer-slap and pellet impact- and I’m pretty content with that!
I did disassemble and polish some moving parts, and applied some Wilson Ultima lube to those moving parts (I’m a firearm guy, just getting into airgunning myself).
It’s actually a very good and accurate rifle so far- I’ve been warned by some here that it’ll end up in the scrap heap (probably because it shoots like a $2000 rifle BUT it’s made by Hatsan), however, I’ve had no issues so far. This rifle, when it’s generally available in the US, might hurt a few folks’ feelings and change a few attitudes, for sure.
Good luck!
