They did indeed - but that was my .177 version. Mr Dave Mercer [ looks to the north and bows ] DM80 on here, did a bit of fettling on my .177 version which made the rifle easier to cock and quieter. Maybe worth while giving Dave a PM on here as he is VERY busy.
One slight niggle with both my KRALs is a slight leak. Nothing serious but Ive had similar very slow leaks on brand new rifles costing four times as much.
Re Polos. I did try to explain I went through the hole but my fellow shooters are no suckers.
