The amazing R-hop test project!

Where are you playing that AEG full auto are permitted to shoot up to 2.25j?

the typical limits in Alberta are ~1.65 or 425 fps.

Super heavy to me is >0.43g IE shooting .8x steel bbs

I run 500fps bolt action. Lotta guys play "big boy" games 500fps on aegs. As far as i know some places play 450-500 fps on aegs all the time.
Im guessing manitoba is one of those places that use higher fps limits.
I personally have no issue with 450 for aegs and 500 for un certified snipers and 550 for lvl2 600 for lvl3 alass i am but one in many and cant change the rules on my own. Plus with the recent influx of "n00bs" especially younger ones i think we are likely better of as is for now (400aeg 450BA)
500 is 2.32j fyi

Their is a hardball group in Edmonton, we play 550 minimum auto, no limit bolt. We picked the 550 minimum to discourage newbies from getting in not that it mattered as we are invite only, I suspect the bottom will rise to 600-680 as most guns off the shelf can shoot into the 550 range nowadays.

2.25j is 495 fps which EAR's Bolt action limit (manual operated bolt no semi auto's or locked to semi electrics).

[ThunderCactus]

max field limit anywhere is always bolt action
max fps of bolt actions is typically 470-500fps
I never said anything about AEG's at 500fps.

.36s are rare enough to come across, I've never even seen a bag of .43s in person lol

Also, Big boy games? IN MANITOBA?? BAHAHAHAHAHA!!!!
Guys here used to complain and force chrono guns that were shooting 310-350fps, the province is not known for having thick skin LOL

Out of curiosity, has the nub that comes with this bucking ever been tried with the R hop?

[Azathoth]

I would look at ASM articles for that information. I use a 3M pad cut to length

[ThunderCactus]

no, but I've used a ryusoku baton and I'd say it works better than the M-nub, at least in theory.
Because it's round on the arm side, it's actually maintaining perfect perpundicular pressure on the Rhop. Whereas the M-nub maintains slight angular pressure.
The difference probably isn't even noticeable, but it would be worth trying a side by side comparison

Also, update, what I'm getting back from the half dozen Rhops in the field;
Most of them are just noticing greater accuracy, not particularly better range
one noticed a "fantastic range" difference, likely because his PDI-W was too tight on the seal and preventing proper feeding lol
And one noticed a big difference because his hop rubber was both stock and crap.

That is what I use with my R-Hop, won't compare it to other anytime soon. It works, shooting great, I'm happy.

I'm guessing the ER-Hop is exclusively only useful for super heavy BBs then...

Yup! One day I'll pick up some .4's+ and give it a whirl, just to see how it performs then. I'm very pleased with how it all works now, even on .28's. I don't see the need for anything "better" just yet. Whether it be this potential part or BB.

I'd love to really test and fuss with the setup, see what it can take... but not now

HS5 actually addressed that directly (I think it's in his video on the LTH unit)

the pivot on hop ups (the m4 ones anyway) is so far back of the actual window that the force applied is near enough to perfect for it to not matter. the material of the m-nub should also even out the pressure considerably (that's what it was designed for). if that's not enough, you can use a snibble or a hop up unit with level travel (but if the fitment is poor, the whole situation can be reversed with the nub applying pressure unevenly in the opposite direction)

[ThunderCactus]

Good to know!
Has anyone else been doing before and after comparisons?
I haven't had the chance to do much since I have no range in my backyard, Wrath is really going to have the best test results since he's right next to a good range.
But so far the comments coming back from my customers are very consistent, if not technically precise; the R-hop is better.

I installed my first all custom r-hop with flat nub the other night in my completely stock G&G mp5 sd6 @ 380~ fps on .20's

Tested today with .28's and a 100' tape.

The gun was shooting decently before hand with the same weight and brand of bb's with an effective range around 160-170 feet. While the bb would fall to he ground around 180 feet.

Tests today with the r-hop had effective range out to 200-210 feet with the bb's falling to the ground around the 220 foot mark.

This was with the hop to the off position and very slightly over hopping the .28g bb's
I plan on getting some .30g or heavier rounds and testing again.

Keep in mind, this was my first attempt at this mod ever... I'm sure there are areas of it that I could improve on. Needless to say I am pretty pleased with the results. Shot to shot consistency was great, accuracy was great, and effective range was an eye opener. 200' with .28's out of an all stock mp5?! @ 380 fps !? I'm sold on the idea. My ptw only bested that by about 20' on .28's and that was @ 420 fps

Yes I'm sure that a pimped out setup with a nice normal hop setup could achieve the same or slightly better results. But bang for your buck, hands down this is it. Hell mine was free plus the time it took to install it.

My custom patch is a section cut out of an old TM gbb pistol bucking from my old 226. Same with the flat nub to match.

[ThunderCactus]

I'm curious to see how your MP5 would have done with a PDI-W rubber as well
We've been finding the difference between an R-hop and PDI-W is fairly minimal on the same weight. Never did get to test both with .36s though.

So far with the same weight of ammo, you're looking at 10-15ft extra with an R-hop, but a much flatter trajectory, and less fps loss from applying hopup

I think this is the biggest reason for the extended range.
I've found PDI W-Holds simply cannot lift .32g BBs without applying a great deal of hop - sacrificing raw range due to loss in velocity.


BTW - we're still looking for a 200ft indoor range. Got the lights, cameras, guns and equipment, if you're in the GTA with access to such a facility, contact us. We'll make it worth your while.

I'll be R-hopping my 249 this winter, I've been waiting for a quality 6.08 barrel since I got my 249 years ago, now I'm torn between a 6.13 orga and a 6.08 PDI =/

[Junky]

Il probably end up using .30g or .32g bb's in the mp5 just to keep the bb travel time to target down a bit. The .28's were getting there relatively quickly so that's also a plus for me.

Not quite the same as with my mp5k doing only 300 fps. But the flat hop mod I've got in there is sending .28's out to 150' accurately... I might try the r-hop patch in that gun too just to see what it would do.
