I have seen several of this dude"s videos in the past and even subscribed to his U-Tube He conveys enormous amounts of information in a condensed manner. I like his stuff and enjoy having trouble keeping up with his information pace. He hosts a HUGE variety of subject matter and ALL fullnny researched.
By the way, my best factory suppressor for a air rifle has a web site showing it's cross section internals. I was impressed with it's unique over/under design. Incredibly quiet Stoeger XM1 air rifle. Check out their website for a education on how to suppress air from a barrel. Crosman Trail SBD (Silent But Deadly) factory offering is my 2nd favorite. It's rectangular shape is very cool! And finally......Allan Zasadney moderators are mouse fart wonderful devices. I own several.
For my affordable PCP .22 caliber Stoeger XM1 I have a affordable Daisy rear peep sight that works perfect with short eye relief and Stoegers optional bi-pod. Also nice and affordable. Entire kit #310.00 Thumbhole Camo stock. Super accurate, decent trigger and QUIET! Get yourself a Stoeger XM! Camo. Best bang for the buck. I already did all the research for Iron Sight PCP. My Crosman Trail SBD is backyard quiet and super accurate hunter too. Mine has a Sig Sauer $400.00 Red Dot. Sight cost more than the rifle. 2MOA Dot, as good as any 4X scope.
