Just received a really nice vintage .177 Beeman R11 MKI and a Bushnell 6-18 Trophy scope, data base dates it to 1993. The MKI has a unique safety & trigger system compared to any of the other R11/HW98's. The safety is not the typical push button that is pushed left to right to release but a lever on the right side that is moved forward to disengage. The safety also acts as an anti beartrap not allowing the rifle to be uncocked. The trigger has no first stage tab to adjust so the trigger blade can have bit of play if adjusted for a light pull. The MKI has a screw on compression tube end block as opposed to the 4 tab and twist out system in all other versions and a separate raised scope rail. The MKI's also have a very short forearm sitting about an inch to the rear of the barrel pivot bolt. All together I have found 4 variations of the R11 although listed in the Blue Book only as a MKI & MKII, I refer to them as MKI-IV here. The MKI as described above, the MKII has the very short stock but a push button safety and dovetail scope grooves, MKIII has a slightly longer stock notched out for the barrel pivot bolt and the MKIV has a stock that covers the entire barrel/breech block. I'm waiting on a tophat for the spring to arrive before I look inside but fps seem good and consistent over the chrony @870 w/FTS pellets.
