Elvish TacR-Hopped ZCI 6.02mm Tightbore Barrel + Modify Flat-Hop Bucking AEG R-Hop RHop

I put this in my Kythera/Krytac build. Replaced some homemade rhop I received. All you have to do is add a little tech grease on the barrel for the bucking, and then on the outside of the bucking for the HopUp. Everything slid on, and it is easily over hopping. .32’s. I can still use them, but to fully use this setup and maximize my range with my Prowin HopUp, heavier bbs like .43’s will be needed. Easily reaching 150ft plus with 32’s.

Ive bought several of these barrels now. Every single one has performed way over my expectations. zci hop is great but the rhop patches and barrel combo are crazy nice for the price. Just finished slapping a p* f2 into my vfc mp7 with just this barrel setup and bucking . im shooting lasers at 200 ft +. I would ignore the negative reviews. As long as you install them correctly and make sure the hop and barrel are aligned you will have no problem whatsoever.

I am absolutely blown away by the quality of the product and the customer service. The product arrived within three days of my purchase date with free shipping, which is already incredible. The product arrived with the r hop patch installed, and came with an extra r hop patch as well. The barrel is a top quality barrel, and is steel as advertized. This product includes the flat hop bucking and flat hop nub which are both made by Modify. The barrel is completely secured in a tube, and comes with 2 o rings for barrel stabalization. They even provided an instruction manuel that describes the best way to secure the product in the hopup chamber. The only thing I will do the increase accuracy is to use barrel lapping to smooth the barrel to perfection, which is already possible because the barrel is steel. I highly recommend this product over all other barrels do to everything that is included.

I have a kwa vm4 2.5 and could not use the included bucking because it was too soft and jammed up and stretched when I installed it. I tried all types of lube and even tried freezing it to try to get it to slide in my proprietary kwa hop up unit. Just didnt trust it so I used the stock kwa bucking with the nubs sanded down very thoroughly and used the nub included with the modify bucking. I have yet to field it but slings .25s and .32s with pretty good accuracy and consistency. I had to actually adjust my red dot up because the bbs werent being dropped so low. Im impressed and will report back when I take it to the field this weekend. Also Elvish Tac is there any aftermarket flat bucking you know that works with kwa rotary hop up units?

I bought this for a Tippman V2 airsoft rifle. The barrel and installed R-HOP cover are fantastic, but I personally had issues with the bucking, as it was too long to allow proper feeding on the Tippman V2. I'd assume this wouldn't be the case on an AEG, but still, something to keep in mind.

I put this in my HPA rifle with an Umbralla Armory Maxx hop with Modify flat bucking. This barrel has made a huge difference in the overall accuracy and performance of my HPA.

Even with hop completely off I could not drop a BB down the barrel. After 70 feet the BBs shoot upwards. Purchased this item to improve range, now I have less.

Product showed up ready to install. Once installed, very pleased with the results.
