I've been eyeballing the Puncher Jumbo Synthetic. Maybe in .22 to sling some Redesigns.
I ordered a synthetic from Krale and so far so good. The cheek riser rocks back and forth in its mount. Shoots crosman 14.3 at 917 fps fully open. I thought the gun would be smaller but it is pretty decent size. Shroud ends right at the barrel end so no sound suppression there. Definitely needs a moderator. I picked up a used huma for it and looking to open up the pathways to turn into a slug gun. Mags are nice and deep so they should work.
Other point: I compared weights once of alu vs carbon fiber bottles. Found that the difference of 100 grams or so really could not justify the big cost difference. (Got my 250 cc alu bottle off Aliexpress for less than 30 bucks shipped ...) Carb Fiber easily costs 100 more. You can pump it up to higher bar than the alu, but that puts more pressure on the seals etc plus I don't care for the look. But that's personal of course ...
I am thinking about getting a smaller 250cc carbon fiber bottle and then installing a regulator with the thought I could pump it up more, it would weigh less and be smaller in size and the regulator would prevent higher pressure to the seals, etc. Would that work?
