Product Information:
The Z kit is very easy to install, and will work for great for those of you playing in snowy environments. These things work wonders! Check my review on the Lancer AK74 w/ RIS! These are come in varying depths, so just cut them to the size of your hop up window and see which one is flush with your inner barrel, then file the outside with a dremel to speed things up and finish up with some 300-400 grit sandpaper, then your done! May need to pop it open again and file it some more if you don't file it enough to begin with. Works great in my M4 too, with the same results as my AK. I am able to hit a 7'x7' target everytime with .30 Bioval BBs..

As a side note to ASGI.... please consider stocking Hunterseeker's barrel laping kits. I don't really want to buy them from other places, and its kind of like polishing a barrel but a bit better.

Increases effective range by about 70 feet or so
Easier to install than the standard r hops
Last forever
Use hard buckings with no added repercussions
Amazes people with your range and accuracy in a cheap gun
3 to install in either 3 different guns, or you have extra if you mess up on your first try

Tad pricey, but worth it
May take a bit of time if you noob around a bit, like I did. But worth it

Product Information:
This is a great kit if you're interested in the r hop system. This set comes with almost everything to be installed. This is a tricky process to install, but if you know what you're doing, or know someone that can install this, you won't be dissapointed.

-nice set of r hops
-can be used in cold
-different selection of sizes for different type barrels
-adds range to your gun!

there is two cons about this product. first being price, for the price you'd expect to get more than 3 peices of rubber, but they do exactly what they're made to, and thats to increase range. the next is the installation process. it is very tedious and time consuming. if you don't know what your doing, you could also risk damaging the barrel in the process, be very careful when installing, or have someone who knows how to do it.

Great but really hard to install. This will increase the effective range and consistency of your gun. Worked great for mine. My KWA CQR Mod 1 came with a bad hop up and I had to replace it, luckily I found this.

Adds effective range
More consistent
More accurate

Very, very hard to install and potentially risky to install if you mess up

Product Information:
After spending many hours finely sanding this part to perfection, I am nearing completion. After test firing to see if I am getting a proper amount of hop, I am quite pleased to say that I have seen a boost in range by about 50-100 feet. My upgraded KWA M4 cqb uses a longer 363mm madbull tight bore and gets perfect compression, so it had long range to begin with (over 200 feet) but now i get very long and flat shots. I am also seeing a jump in velocity; before, my gun shot 344fps, only slightly piercing the bottom of a soda can, but now it is shooting completely through the bottom. My groupings are also tighter. For skeptics and others who are doubtful of how this can make such dramatic improvements, I will now state the theories as to why this works so well:

Range: this is the tough one to explain simply, but i'll paraphrase the theory that I have come to believe. On a traditional hop-up, backspin is applied very quickly, since only the bucking's hop mound protrudes into the barrel. This makes the axis of rotation above the bb's geometric center, causing the bb wobble while in flight, effectively increasing air resistance, and slowing the bb more quickly. On the rhop, backspin is applied much more slowly, allowing the axis of rotation to be directly or at least much closer to the bbs geometric center, significantly reducing wobble, and therefore allowing it to pass through the air more easily. Again, a little theoretical, but it does make sense.

Velocity: with the rhop patch being the contact point of the bb, one can choose the bucking that seals the best without worrying about performance. I was able to use my old KWA bucking which sealed air much better than my 2gx bucking, even though the old bucking was long worn out. Since The contact mound must be removed, I could still use my old and better sealing bucking. I gained a lot of fps as a result, but results can vary greatly in terms of fps.

Accuracy: This is obvious. The patch contours to the bb, fundamentally increasing accuracy. The patch is also pre-fitted to give desired hop, so inaccuracies of the actual hopup unit are eliminated as well.

As great of a product this is, I would ONLY recommend this to more skilled airsoft mechanics because everything must be very precise. I used 400 grit sandpaper and a dremel and sanded and ground this to fit perfectly, as anything less will cause flyers, overall loss in accuracy, etc. There are many guides to install this online, so i'll leave that to the customer to figure out. But overall, this WILL make your gun perform like a champ, but only with the patience and craftsmanship to get it right.

Increases range a lot (id say the average gun should gain 75 feet of range, assuming everything will be done properly
Increased accuracy
Allows the use of the best sealing bucking, so I gained fps in the end (search "aeg floss mod" on youtube for a great way to maximize airseal)

reliability might slightly go down, because the possibility of a pinch jam is greater since the patch is not connected to the bucking. If it does cause problems, just glue the patch to the bucking by following the online instructions mentioned above. I've had no problems with jamming, but i thought it might be good to point that out.

Really, nothing else. Labor, fine tuning, and the need of tools are not cons. they are a part to this product and should be expected. Just be patient with it, and the many hours you could be potentially spending will be worth it. Nothing is more gratifying than watching your bbs fly and fly until you lose track of them when all is said and done.
