Just bought a bsa r10 mk2....

They are long and I think the same but all the nice rifles are long....example raw,cricket rifle,air arms 510(not the carbine standard) ,streamline after you install ldc,mrod only a inch shorter and even all hatsan rifles are 43 inch plus . I'm using this one for basically my deck benchrest ....look at the write up about that red wolf and after LCD is installed 51 inches. I have a compatto and a condor ss for the woods and hunting.
 
They look really long in pics. You can also cut the shroud off to match up in length to the shoulder of the threads on the barrel and use a suppressor or you can completely remove the shroud if you want to be able to go back to stock form and use just the suppressor. I lost an inch or more doing that and its quieter than the shroud. They dont vent the bushing in the shroud so none of the shroud behind the muzzle is used to capture air. Overall length with the shroud cut and a 6" suppressor is 42"
 
I did the same deal 15% off $40.00 in Bonus Bucks A regulated 177. for under $500.00 bucks ya. Iv had mine for 3 weeks and love it very accurate and quite the single shot tray is worth the price also.So far seems to like H+N Barracudas and JSB both 10.gr. Haven't shot it over the chrono. yet do to lack of air,filling all 3 of my tanks this weekend and will run some strings. So far no problems at all I like mine A LOT
