New to SCS - Shaving hop-up sleeve mound?

[Rabbit]

Recently installed an SCS into my hop-up after reading numerous times about the drastic improvements in range etc.

I'm only now finding a graveyard post on ASC from 2009 that states you should clear off the mound inside the hop-up sleeve in order to get the best "shape" by Shredder himself.

Upon further investigation i've also read that you should shave off the mound AND rectangular strip and turn your sleeve 90degrees for the best flat surface for the SCS to work properly.

Can anyone attest to this?

I'll be working with a guarder "improved" black sleeve and madbull python.

My teammate Ding (buddy of mine you saw at our last game with A-TACS) is using this setup and has definitely cleared the internal mound and I can verify having fired his rifle that it resulted in some very impressive accuracy and distance compared to the stock G&P setup it had beforehand. I am unsure about the other parts of your question though.. I'll have to ask.

Yes, you should get better results. This works with soft buckings better than hard ones. If you install a Firefly Flat nub, or simply make one, you can get even better results than with a SCS.

So I decided to try a stock VFC hop-up sleeve for the shaving - super squishy soft to the touch - shaving off the mound went perfect - better than perfect - its almost as if it were never there.

After piecing together the inner barrel, sleeve, hop-up unit etc. I slip in the SCS and as shown in the picture - when pressing down on the arm this is the most amount of hop with the SCS I can get.

I tried 3 more different hop up arms with the SCS and received the same results

Help!



Should I be aiming for this??? (taken from Shredder's site)

Use a drop of hot glue to raise where the SCS sits on the arm. I shaped mine with a Micro screwdriver while being sure it was perfectly perpendicular, worked like a charm.

You will get an adjustment range that is far better

I personally think that if you're going through the trouble to put in a 'proper' moundless SCS install, you'd be even better off with an R-hop.

I did a moundless SCS install recently, and while it was quite accurate, I couldn't get enough hop to toss 0.30g+ without encountering jamming and extremely accelerated wear on the hop up bucking/sleeve.
For reference, the way I solved the problem you are having right now was to use a dab of hot glue as flack suggested to keep the SCS orientation fixed, and also to super glue a thin layer of plastic on the inside of the opening in the hop arm that the adjustment cams against, shimming the whole arm adjustment range lower.
The setup eventually died by stripping a piston due to a hard jam.

*for reference, I was using a Guarder Clear bucking. That might have exacerbated some of the problems I was having; they're pretty well known for not being the most durable things around.

I'm definitely just going straight to R-hops in the future. They're far less susceptible to these problems and almost impossible to wear out, as well as offering similar (arguably superior) accuracy potential.
-bonus, the work you put into shaving the mound off is equally applied to an R-hop, which also uses a moundless bucking.

[iKliiu]

Having done both, SCS/Flat nub installs are definitely easier than a R-hop install. However, once you get the R-hop installed, results are absolutely amazing.

Only thing is, if you screw up, there goes 1 of your 3 patches.

Man i sat at my work table for like a good hour trying to get the hot glue method to work. I crumbled and gave up. I couldn't get the SCS exactly straight - it was always crooked.

Mind you im dealing with a JG 2 piece hop-up and this gave me some time to really pick out the minor flaws - so being a 2 piece getting anything better is fairly limited.

R-Hop will have to wait - im going to see how the local gundoc goes on his first install so maybe after -

Edit: FUCK IT. Too much tinkering - not enough patience! Going to just try SCS with ARS sleeve and let it wear down.

I use a SCS in my G3. This is the first I have heard of "shaving the mound". Just installed one in my m14 this morning as well without touching the rubber. Both guns shoots amazingly. If I have a moment I will take a pic of my g3 hop up.

I remember your G3 from FR - picked me off from a mile away it was insane.

What inner barrel and hop-up bucking combo were you using?

Madbull 6.03 with a guarder black
