Best Hop-up

Recommended Posts

I am looking to upgrade my ICS AK74 hop-up unit. I am looking for something geared specifically towards Rhop, as I am also going to get a Prometheus 6.03mm x 509mm inner barrel, possibly with the Rhop patch pre-installed. I have searched Evike, Redwolf Airsoft, Amazon and Ebay (the last two I don't usually trust for qualityairsoft parts), but to no avail. Are there any specific units I should get/avoid? Ultimately I am looking for maximum consistancy and range. Any Ideas? Help would be greatly appreciated. Thanks.

Any reason why you want a barrel that long?

You do realize with R-HOP you lose ammo flexibility, right?  

Now if you want 93% of RHOP performance, yet have ammo flexibility and not needing a 509mm barrel.  You can just put on a MR AEG packing at 50 degree durometer, shoot .28g medium polish bbs on your stock barrel and you can range out to 90 yards with a 400fps AEG.

The stock barrel on my ICS AK74 is 509mm. What do you mean: "MR AEG packing at 50 degree durometer"? Is that a specific product?

Is that barrel running through the Hider?  Most end at the outer barrel and thus AK's average 455mm.

Yes sir, the latest and the greatest from Maple Leaf for R-Hop type performance with slip-on simplicity.  Came out last Feb in Asia and with the right barrel...it has pushed long range consistency quite well.

No, the barrel does not go through the flash hider. I made the mistake of trusting the description where I got it, and not measuring it. A thorough measurement shows that sure enough, it is 455mm. Darn you, Evike! Good thing I didn't purchase any replacement barrel.

Anyway, do you know where I can get this Maple Leaf R-Hop-like product? I googled "maple leaf airsoft hop-up" and only came up with what I assume are older versions. Is it true that just changing your bucking/packing can so dramatically improve your range? Does the nub need any changing/adjusting? And if I did find it, what price range am I looking at?

MR Hop-Up rubbers can be found at Airsoft Atlanta and on eBay being sold by a guy that helps the little fellows out named Gugesmk3.

You can get a Packing and Nub for 22.00 shipped.  You may have to enlarge the window to accommodate the better packing/Rubber though.  because it is R-Hop like in performance and not like the traditional legacy type.

If you use a MR and a ML Omega nub hollow or solid.  It works far better than a MR and a traditional round nub.

You can ask the Refugees of ASF that went to Airsoft Society when ASF went down 2.5 years ago and never came back.  Many have used the ML packings/rubbers and nubs to effect that is better than the legacy system without the hassles of an actual R-Hop.

Here is developing thread about the latest marketing shenanigans and how the packings look on the inside.

Thanks, I found the product on eBay. I just need the "MR 50" and the "Omega Nub Hollow", right?

I also noticed some rather disappointing FPS issues with the same AK. The internals consist of:

SHS Metal Toothed Piston (swiss cheesed),

SHS Double O-ring Cylinder Head,

Crossman Tappet Plate,

Lonex A2 High Torque Motor,

Maddog M140 Spring (reported to give me 459 FPS),

SHS Metal Spring Guide,

Maxx Aluminum Double O-ring Piston Head

**The Maxx Piston Head was a bit of a mistake, good quality but heavy and with the unnecessary ball-bearings.**

The issue is that even with all these upgrade parts, I can't seem to get more than 270 - 300 FPS (w/ .25g BBs). 

I don't know what Maddog springs are (hard, semi-hard, etc.), but with this result I suspect that they are soft. I'm not sure of the FPS immediately after installing the new spring (since I just got a chronograph), but I suspect it hasn't changed much. The Maddog spring is pretty easy to compress into the gearbox, maybe even easier than the stock spring (M130?). I did disassemble the gun and check the compression, and was not impressed. It was terrible. After checking the piston head I adjusted the O-ring (enlarged it) and reassembled the gun. If anything, the FPS dropped! 

Do you have any idea why I can't get more than 300 FPS with these internals?

Don't know who the heck is "Maddog", could they have put the wrong spring in the wrong bag.

That happens more often than not for these "off" brands.

You don't need a double bearing in the mechbox.  Heck, you don't even need bearings.  Bearings in the mechbox is a throw back to a design mistake with SystemA springs.

 

How long is your stock barrel, have you tried the magwell tissue test?
