KM have released their own hop rubber for VSR type hopunits. The other day I ordered one from WGC (KM RH55 hard version) hop rubber, seeing there are a few aftermarket hop rubbers for the VSR i thought i should get to try them all out, having used the Nineball one, the firefly hard, and now the KM RH55, i thought it fitting to write up a small review of the KM one.
First part; KM RH55 Hop Rubber
Initial Impressions:
Feels quite nice and rubbery, more so than the firefly, and definatly feels 'harder'
in comparason the firefly nipples seems to stick lower than the KM one, this gave me reservations as i thought if im having trouble with the firefly overhopping .36 this KM one isnt going to do the job.
Fitting:
Fitted the hop rubber and added a few layers of PTFE tape as normal but i was a bit concerned with this:
as you can see there looks to be a bit of space around the hop rubber and the cylidner head. this could be sorted with some tape around the nozzle. my fps recordings on the chrono were fluctuating 10fps though, from 480-490fps
with the firefly im getting spot on 499-501fps
Shooting:
Next up is the range:
thats the range im shooting, each bottle is slightly smaller than a human torso and the ranges are listed there.
Our engagement distance is 20m, but i personaly think thats to low and as such use a self imposed of 30m even at the 37m target i hit where im aiming every time so ass/leg shots are popular as they hurt less.
55m how ever running .36 Digicon non coated, im getting bout 8/10 shots hitting the bottle or the tree or going an inch to the right, there was a slight breeze which was crossing the shooting range how ever.
the SGM's at this range were pretty much equal with consistancy but were more affected by the wind and was more like 7/10 hitting.
The tree with the red dot is 60m the .36 were hitting this and going straighter a hella lot more than the SGM's this wasnt shooting into the crosswind though. but still, as ive said previously ive always found the digicon ammo to be more consistant in my pdi 6.01mm barrel than the SGM's every one raves about.
the main thing is i can over hop .36 now which allows me to get maximum range which is bout 60-65m straight before dropping this is at just under 500fps.
pretty much guaranteed first hit at 40-50m then 50 - 60m first or 2nd shot.
Edit - August 2009: Ive been running this hop rubber since the original review, and once it bedded in its been running great, I personally prefer it over the firefly one, so next time you order from WGC chuck one in on the order and take a look yourself. (currently using madbull .4 with it, with great results).
