Reviews & Ratings for V Seven Extreme Environment Gas Tube — 15 reviews — Page 1

I like it. Definitely well built very sturdy. Pricey for a gas tube. But well worth it.

I used this for a build of mine. Works so nicely, I've had no problems with them at all. They're a bit pricey, but it's a super cool material.

If you are building something that cost a lot what’s a little extra for some peace of mind knowing your gas tube will not fail. I use this on all my builds and to me the peace of mind is worth and the quality of materials speaks for itself

These gas tubes have a taper and larger diameter than other gas tubes. Will NOT fit the gas tube hole in Aero M5 upper receivers. You could drill out the hole so it fits but when you go to use normal gas tubes they will rattle around and not align with the gas key. If you try to install one of these in an Aero M5 you will scratch up your barrel & gas tube in the process.

Overall, this is an outstanding gas tube. The build quality and design improvements are apparent just by looking at the gas tube. The gas tube body is slightly thicker than a standard stainless steel gas tube. And the gas key collar is not just a widening at the bolt carrier end of the gas tube. It's a thickened lug that machine (or molded) into the gas tube.

Yes, this robust construction can cause fit issues with certain upper receivers and barrel nuts (notably, the SLR Rifleworks barrel nut). V Seven says this is not compatible with Aero Precision M4E1 upper receivers. But I had no fit issues using this gas tube in an M4E1 upper. Your mileage may vary.

In any case, as long as this gas tube fits, it's an impressively high quality part. And could be worth the rather high price if you're after a bombproof gas system. Though, most people don't NEED a gas tube this robust, since most people don't shoot full-auto or do high volumes of suppressed fire.

There's no penalty for having too much durability, in most cases, though.

I've tried just about every gas tube available. The fitment for a standard tube vs this aftermarket aren't completely universal depending on your gas block. Out of the 8 different gas blocks I tried, all were a great fit. The only downside to this gas tube is the gas tube is designed to fail first in an overheating situation to prevent a gas block fatal failure. This gas tube will outlast most barrels and gas blocks. It is lighter, beefier than a standard tube. It isn't necessary but definitely adds to your lightweight or shtf build. I wanted the most durable materials for my build. With this, I have it. Good luck finding a better gas tube.

Most ar15 owners will likely never need to replace a regular gas tube. But if you want one that you guarantee that then this is the one for you.
If running full auto, binary trigger, etc. this also would be a good gas tube but would need to keep an eye on barrel temperature to make sure you don't over heat the barrel in too short period of time since this gas tube likely won't be the first thing to malfunction like it was designed to. If you can afford to dump magazine after magazine with ammo prices as high as they are right now I mean.
It's thicker than the average gas tube leading up to where it enters the upper receiver so will not be compatible with all barrel nuts for all hand guards without maybe some modifications to the barrel and/or hand guard. It fit Midwest industries SP rail and aero precisions enhanced gen 2 hand guard without any modifications.

Does not fit Mega Arms uppers. The description did not say anything about not fitting this upper (both on OpticsPlanet and V Sevens Website), so I thought I would be good. I have to use a standard gas tube. This item arrived promptly when I ordered it in March, but had to wait several months on a barrel. Since OpticsPlanet had almost a year wait time on the barrel (after first posting it was only going to be a month) I had to order from someone else, but that put me outside the 30 day return window for the gas tube when I found out things would not fit. I now have a very expensive drinking straw.

If you're looking for the ultimate gas tube that will last or outlast the life of your rifle, look no further. This gas tube is made of the same material most modern suppressors are made of. Suppressors capable of withstanding full-auto fire need inconel in order to last, leave it to V Seven to use that same material to model the toughest gas tube out of. Not only will it survive temperatures that would render your standard gas tubes into a curly noodle of scrap metal, it won't ever rust or corrode. I use these in all of my builds and love the quality of the construction and the fit and finish. When you hold it in your hands you can just feel that this is one bad mama-bama that has no equal. OpticsPlanet was quick to get this shipped out to me as well, so there's that. Is this gas tube worth the premium it commands? If you want the weakest link of your rifle to no longer be a possible liability when you need it most, YES- absolutely!

Amazing gas tube 99.9% of people don't need. I will never get the gun hot enough to pop a regular gas tube, but I like to overbuild things and waste money on parts to get that warm and fuzzy feeling. All jokes aside, people buying these tubes do not understand how the AR-15 is meant to operate. The gas tube IS supposed to be your point of failure and you won't be shooting enough rounds to reach that point regardless. Unless you are doing 20 30round mag dumps on a full auto lower this item is pointless, not to mention your barrel will be scrap metal after said activity. Spend your money on ammo and training maybe even a book about the very system you are using.
