28rd magazine for R615 TTI Sand Viper [JAG Arms]

Incredibly good price on those, can't beat it.
Unlike the "EMG" branded versions, the Army mags will work with any hi-capa pistol no issues. Made the mistake to buy the "baba yaga" combat master mag once thinking the same should be true, but it wasn't, so these working in everything else was a nice and welcomed change. Don't have a chrono to see actual fps, but so far they seem to hold a reasonable amount of gas and don't leak, even after dropping them from my Pit Viper (that mag release is a crime) from 1,5 meters on hard floor several times, the base plates didn't break and the mags still work..

I picked up the 28-round magazine for the R615 TTI Sand Viper by JAG Arms to use with my R614 TTI JW4 Pit Viper GBB Pistol, and it works perfectly. Fitment is excellent, locking into the pistol securely with no wobble. Feeding has been flawless, and I haven't experienced any jams or misfires during use.

The magazine feels solid and well-made, holding gas efficiently and providing consistent performance throughout each fill. Reloading is smooth, and it inserts and releases just as it should. It's always nice to have an extra magazine during games, and this one has proven to be completely reliable.

Overall, I'm very happy with this purchase. If you own the R614 TTI JW4 Pit Viper GBB Pistol, this magazine is a great option. It has worked perfectly for me, and I wouldn't hesitate to buy more in the future.

Nice inexpensive mags for Hi-capa. I bought them for my jag arms Sand Viper, but they fit other Hi-capa models as well. The main pro is that the mags are relatively cheap. They work perfect and I bought a lot as spares.

This magazine is the perfect companion for the Pit Viper. The gas seal is excellent and the feeding is flawless from the first to the last BB. I really appreciate the matte finish, which matches the pistol's aesthetics perfectly.
Compared to the extended version, it makes the pistol much more compact and easier to holster, while still providing enough gas for more than two full rounds of BBs. No leaks so far—JAG Arms quality is consistent and dependable.

The "28rd magazine for R615 TTI Sand Viper [JAG Arms]" is fully compatible( cycling and lock the slide back when the mag is empty) with the "R601 JW3 TTI Combat Master - Black [JAG Arms]". I took the risk and try it so no worries

Had one leak on me pretty soon. All I needed to do was to resecure the valve. However, the baseplate doesn't colour match the AA TTI Sand Viper Upgraded version.

Be aware of that when you purchase the packaged deal with the Sand Viper from Action Army (upgraded version).

A great magazine that works perfectly with my JAG arms Sand Viper replica. Smooth and easy to reload with green gas. Comes with a little gas in for leak testing. I recommend this as a backup magazine for shooting sessions.

As expected. They are very oiled from the factory and needs to be taken apart, dried off and re-lubricated. They look awesome.

Haven't been out with it yet, so I don't know how they feed, but they look right.

This is my second time buying this maginze and I bought 3. It is very well made and compatible with different tti 2011 replicas.

With lower price, it is even better than double bell magazines.

One fill, I can shoot 2 full mag of bbs and the slide kicks hard. No leakage from 4 I bought so far.


The buttom slide is wobbly and that is the only thing I can complain for it.

Really good mags. They look nice, the fitting with R615 Sand Viper is almost perfect, feeds well, slides in and out smoothly. Holds around 2 mags of bbs in gas, which means you dont need to refill gas everytime. So far I have not noticed any gas leaks. The mags are pretty sturdy, have dropped them accidentally on concrete and they still work very well, but cosmetically the damage doesnt look too good.

I would be careful with mag pouch selection, as these mags are pretty large so they dont fit very well with 9mm mag pouches and they are heavy so they can fall out when moving if not properly secured.

They can barely get through the whole magazine without running out of gas. Also, these magazines aren't compatible with HPA adapters (FUKU-2 specifically) as they have different bottom parts than TM or WE mags.
