Well guys I'm curious to hear some opinions on hopup buckings. Since I've been going through and fixing guns I've run into a couple that are likely to need new bucking's fairly soon since the hopups aren't working great. One is a CA M15A4 that is very likely running the stock CA bucking, which from memory weren't very good especially compared to a TM. In the past I typically ran TM buckings but they seem pretty hard to come by from what I'm seeing. And the brands I'm seeing I've never had any experiences with so some ideas would be appreciated.
Another one is my TM VSR10 G-spec, it's running a TM bucking right now but when I had it torn down I noticed it's got some dimples where the arm makes contact that aren't rebounding. Also it's running fairly consistent but a little light in hopup compared to what I expect with higher weight BB's. I've modded the arm slightly to put pressure across the width of the nub rather than the H style that it used stock. That helped but I suspect a new bucking will be in order soon, so brands on that would be appreciated I'd like something that will be at least on par with the TM in good condition etc.
So I appreciate any insight on some of the buckings out there, I've done a fair bit of reading but haven't found a ton of good info. Allot of the time it seems comparing them to stock bucking's from some of the cheaper clone companies which I suspect are pretty terrible. I'd like to know how they compare to a TM bucking since that's what I have the most experience with, honestly I think around 8 of my current long guns are running TM buckings at the moment.
Thanks!
Luke

Lonex and Maple leaf make good buckings in varying degrees of hardness.

Lonex and Maple leaf make good buckings in varying degrees of hardness. That's good news Lonex was one of the brands I saw quite a few of. Also that brings up another question, hardness. I'm not sure what stock TM buckings are hardness wise, as I understand it the number is durometer for the hardness of the bucking. But I'm not sure what level is better for what application either. From what I read harder buckings last longer but less hop, some guys say soft in higher FPS applications will tear etc. Input on that front would be appreciated as well;) Take care! Luke

I swear by the Modify Flat Hop Bucking/Nub package.

I've been thinking about possibly doing some sort of R-hop or one of the variations on my VSR10. I went ahead and threw a stronger set of sears and higher spring in it a couple weeks back. And I've been hitting pretty dang consistent out a ways, but temps seem to be effecting my bucking as well. I notice that the first several shots are not hopping like they should, then it will get good. If I let it sit for say 10 minutes then it does the same thing. I suspect it's the temp of the friction making the bucking function, then once it cools get's more rigid and less hopup as a result. I've heard those R-hop style buckings and material aren't nearly as effected by temps but I haven't seen much on them yet. I have been reading a bit about them but it's a touch confusing to just read about I need to watch a few more videos to get a feel for it. Right now though with the stock TM bucking I can easily take someone out past 50 yards, and the last game I took a couple at what I would guesstimate is around 75 yards. The 50 yards I verified with my laser range finder, the 75 was a guess in game so might be a touch further or closer but it was certainly a fair bit past the 50 I use to test the gun(old camper outside my shop 50 yards from my door). All in all I'm very interested in getting that VSR to reach out as far as possible while not spending a fortune, I think hopup bucking, maybe a TDC mod should get me a little more out of it. I do have a bug to build an M14 though so I may end up selling one of my other AEG's out of my old school stockpile and putting some money into that project;) I really don't need 10 long guns;) Luke

The IER hop is the rubber compound that they designed for colder temps, so that might be the one to go with if you're concerned about temperature fluctuations. They have many different types of buckings to can choose from. Fitment however is custom to each gun as you have to cut and file the rubber itself. Its not difficult if you know how to use an exacto knife, it took me about 30 minutes to install mine. I WOULD recommend getting the Rhop tools with your order. R-Hop, M-Nub, and the shaping tools total work out to about $30 after shipping. It has been a while since I've ordered and prices may have changed.

I have the Well MB-03 version of the VSR/Bar10, and the hop-up is rather terrible. Back when I was more into airsoft I had the TSD M700 (same thing ish) and had the hopup going really well on that, cured the right hook and very strong up up for >.3g bb's. That gun could really reach out and touch something, but now that I've fixed the hooking problem on my MB03 I don't seem to have the strong hop characteristics to float a heavier BB out far enough to justify carrying it over my M4.
The IER-hop looks exactly like what I was looking for. Ghost, have you used the IER-hop on a spring rifle as well or just the GR25? I might just go buy that hop and see how it goes. I got all giddy once I fixed the classic hook issue, but I still can't run much more than .25's without having the hop to carry them very far.

Prometheus Purple Buckings are very nice for the around 400 FPS area. Their Red Buckings supposedly have some fitment issues though.

Guarder clear buckings, with SCS nubs have found their way into over 50% of my primaries.

I loves me some Guarder clears, nubs and buckings both.

The flat hop bucking and nub is the same basic concept of R-Hop but its just a straight drop in, no custom fitting or anything, less effective than R-Hop but I prefer it due to ease of install. Still an instant boost of 50ft+ to your range.

So if I'm understanding the way that flat hop works, your basically using the hopup sleeve minus the mound lacking a better term that would be in a normal hopup, and a flat nub to press down rather than a normal wire insulator shaped nub?
That's what it looks like and just wanted to confirm I'm seeing it correctly. I might actually put something together like this to test if I've understood it properly.

You're right on the mark there.
