Modify Baton Ryusoku Flat Hopup Bucking for Airsoft AEGs (Model: Soft)

"Bought a couple of these before an event to replace the stock bucking.
These work outstanding. I have a G-36c (Ares, Umarex, H&K, by Elite Force) I had to sand down the "legs" on my "arm" that pushes on the nub so that it didn't protrude into the barrel when hop up was fully off, but other than that these are great.

"This bucking... Is amazing! A great price for something that actually works! Buy this bucking and the H-Nub or P* concave nub plus a TBB and you will fall in love with this set up!

"My friend installed this in his VFC HK 416 and was hitting nearly 200' with a fairly tight spread. This bucking is definitely worth a look at for anyone wanting increased accuracy and range.

"This flat hop combo greatly improves the consistency of longer range shots. I had to trim the end of the bucking where the BBs are held in the hop up chamber. It was a couple millimeters too long for my cybergun p90 hop up chamber and was causing some feeding issues. Trimming a couple millimeters off the end didn't seem to affect the overall performance of the bucking. Hops .30g bbs easily and accurately

"Does not fit into KWA VM4 2.5 Rotary Hop, the bucking is just too tight. I did use the nub however with great success with a pink Maple Leaf 75 degree bucking. Also a very very tight fit but everything went together fine and it now overhops .25s and .28s to the moon on the lowest setting so im going to grab some .30s or higher like many recommend. Im sure if the bucking was a little less thick it would fit fine and work flawlessly like others have posted but KWA as always has some fitment issues which i knew beforehand and bought two buckings just in case. Glad i did.

"This bucking is super soft! But is great for improved accuracy. Since this bucking is so soft the durability is not that great. If you are looking for improved accuracy and compression get this bucking but just note the more hop you give the more likely your going to wear it down at a faster rate and create a lovely hole. Had this running around 330fps to 350fps and ripped through the hopup contact in about 2k+ rounds. But I have very high stress builds as well 50-60rps. So I will go out on a limb and say that had something to do with it.

4 stars just for the durability aspect but I guess that is expected with a soft bucking
Overall great accuracy and compression performance.

"I got this bucking about a 2 months ago and have played at two Lion Claws games and one local game and while its good, I cant give it 5/5.

Gun specs:
G&P MOE M4 305fps/ .25's at latest crono
Prommy Barrel
Stock G&P Gearbox (they are dam bullet proof)
Stock G&P hopup chamber (meh only so-so)
BTS Chimera v2 MOSFET

Pros:
-Super consistent horizontal grouping. Seriously, at 150ft with little wind I was hitting a tree 8" wide 9/10 shots if not 10/10 with .32g BB's.

Cons:
-Super hard to adjust with a stock hopup unit. Even with using .32g BB's, they were either dropping at 50ft or zinging upwards. I plan to get either a prowin or a prommy chamber before next year to try and help with that.
-Vertical consistency was terrible. This is due probably a few things. First of all the difficulty setting it from con #1. Second possibly again due to my hopup chamber but I had no consistency issues with a SCS concave spacer w/systema bucking in the same chamber. It was so inconsistent that I was fiddling with the hopup every 30 minutes or so at the Op I was at this past weekend. Very annoying.

A few other points. I saw no added range with this vs. a SCS nub/systema bucking setup or with a custom R hop setup. Very easy to install. For the price though, 4/5.

"The nub is a huge pain to get to fit in some chambers but once you get it in this is a fantastic bucking/nub combo and will out range just about anything. This is the first thing I put into all of my AEGs now.

"Flat hop nub is very nice, the bucking required modification however. The lip was too long and resulted in jamming and not passing the 'bb drop test' in the hop up chamber. Had to sand down the bucking lip until it fed smoothly. Once it did, the bucking and nub combined with my ZCI barrel made for a pretty accurate rifle!

"I know this bucking has potential but I must have gotten a lemon because after 50 rounds it ripped the lip off. I’m no noob and I have put many buckings in my rifles before and have never seen this happen.

"I had high hopes for this bucking and nub after I lost my stock nub. When I installed this on my Matrix SR-25 along with a Madbull tightbore, I was having serious issues with underhop. I would increase the hop up at a regular pace when, suddenly, I was having serious overhop. The adjustment on this nub is so coarse at the higher levels that even the cycling of a gearbox and the slight movement of hopup wheel causes that the BB's to begin under and over hop erratically. I gave this a three because I am new to modifying my guns and it is completely possible that I made the mistake in this installation. If I do find that this was my own error, hopefully, I can correct this and I will promptly change my review. Until then though, very disappointed.

"The bucking itself is pretty decent, it's a fairly soft rubber which means the durability will not be the best. However, the nub is much too hard and does not provide enough squish for consistent performance. I've had better results using a firefly nub or a prometheus flat nub.

"Although I'm happy with some of Modify's other products, this HARD bucking (color: black) was extremely soft. I don't think it's sufficiently durable for use in any of my airsoft collection, whether the muzzle velocity is 300 fps or 500 fps. It is about the same softness as the stock soft bucking that I was looking to replace.
