Bullpups I’ve owned:
Maverick Compact 177
Cricket Tactical II 60 25
Snowpeak P35 25 cal
I don’t want another CF bottle gun. Just food for thought. When I want another higher end bullpup, it will be a cylinder gun. The little bit of height the bottles add feels huge to me. I have a Great White to fill mine, so the shot counts aren’t as important to me as a maneuverable platform that shoots from a bench well.
I only suggest you try and hold some stuff and get a feel.
And I would never buy another Maverick. There is plenty you can read in threads about issues people have. Mine was POI shift. I spent more time tuning than shooting.
Your application is very similar to mine.
