Extremely reducing recoil; only if you do it right and you have to open up your airgun yourself with a compressor.
Most airgun oldfashionschool diehards are sceptic about this cheap method because it is beyond their imagination. Maccarri set sellers / owners?
I have Gamo hunters 1250 and cf 30 what i did is taping the springguides with duct tape; the black one is smoother then the gray one.
Clean your springguides;
tape the rear spring so that it is though to turn the taped guide into the spring, but it goes. Though to pull out.
Put the tape real tight and smooth turning on the springguide, so it won't creap up.
You do the same on the front springguide; extra to the front springguide is that you also tape the outside part so that in fit's real tight in the piston.
with the front bit a bit folded over the edge so that it works as seal preventing metal against metal in the piston.
Use black molycote on the spring and triggerparts inside.
What you get is a very tight and smooth movement within the airgun with hardly any recoil.
Easy cocking.
Accuracy
What to do next; make sure your stock is real tight fitted to the action;
shooting means heavy bangs; so you have to check ALL your screws once in a while.
Next adjust your trigger to a lighter pull or better get a GTXIII.
In the militairy you have regulair checks on your gun but in civil live people seems to forget?
The uncontrolled force of the spring is now reduced but you stil have the big bang forward; a little reduced by the overhanging tape.
Also the tape demps at the well of the force.
A scopemount with pin prevents it moving on the rail.
A dampa mount can help, but needs a pin.
There are springrated scopes that is an option.
Bushnell sportsman helds on my cf 30 (290 m/s)
Gamo 2-7x32 AO on the 1250 .177 using cp heavy pellets
What also very good works is the Gamo 2,5x2 they use it on the hunter 890.
only outside lenses and no inner lenses
That is what get's damaged in a scope. The small inner lens comes loose.
This is a cheap brandless scope that died on a 1250.
Try it yourself and don't listen to critics who know everyting but havent'tried it properly. Teflon kind of new springguide don't damp; the tape does but is more sensitive and needs to be replaced earlier.
My tape lasted at least 5000 shots each and after that i opened the gun and renewed the tape. Stockscrews are adjusted and checked every week. Scope mount also.
You take your car for a MOT! Do your gun also, when taped.
the scope shooting in.
shoot first at 10 yards and then try 20 and the 25-40 yards.
You will notice a very big difference.
Big advantage; you are in control of your gun (and money) and not some-else.
As in the militairy you maintain your gun; do your airgun also. Yourself.
I do not comment on al the proven good professional tuners, but this is something else, you can try yourself, see if it works for you and if this is something you want.
I like it and it works fine.
The cf30 shoots easely small coin groups at 35 yards; Like a hk97k with maccarri set.
and the 1250 at 20 yards.
The 1250 needs a better trigger. Is on its way.
The Hatsan 125 probely also needs that due to the springforce on the trigger.
You need a softpull to get your accuracy better.
See the tape as the rubber joints in your car suspention.
They work great and better than the old springsuspention but need to be replaced after a period of time to keep the car driving smooth.
The Hatsan can be controlled this way just like the Gamo Hunter 1250 and will shoot like a dream come true.
Try it and make some photo's
