Premo. I have the Beeman R-1 with 66R Scope since new. She's likely due for some quality tuning-overhaul. That's a can of worms at current day with who to trust.
Yeah, I've drooled over rifles like TOTL Daystate. I sort of liken it to a very expensive state of the art Road Racing Bicycle. You're gonna spend some wicked money. Yep, the Compressor, this and that, scopes, mounts, scope stops, this add on, and that add on, etc, probably not that hard a gun to maintain, but surely a high precision air rifle. One with a lot of investment of money and time.
Imagine one in .25-30 caliber? These are then Air Rifles in another realm of performance and lethality.
Top Flight Match Air Rifles never were cheap.
Cost per dollar, as for performance, upkeep, simplicity, ease of use, build quality, I'd say the Spinger reigns king.
I know I've taken some mighty fine shots and at quite long distances with my R-1 when she was in fine tune.....and after I "settled" her down and she wasn't rattling-vibrating herself apart. It was a Rifle that required some good use of #242 Loctite just about everywhere.
Downside with these conventional springers, that loudish Twack, and that bit of vibration and forward lunge. Opposite of a Firearm.
