Umarex Octane trigger job

by DMoneyTT

As the cost and availability of firearm ammunition continues to keep many shooters from getting adequate trigger time, scores of shooters are turning to airguns to keep their skills honed. Often, new airgunners will be tempted to put down their hard-earned dollars on a rifle offering the highest advertised velocity. Airgun marketing tends to focus on this aspect of performance over all else; but experienced shooters know that accuracy is paramount, and it takes more than just a good barrel and powerplant to deliver tight groups. Proper fit and trigger control are critical considerations when attempting to extract the maximum potential from any rifle.

Octane combo from Umarex: Part 4

Today’s report is both interesting and a little different. I shot the .22-caliber Octane combo from Umarex at 25 yards and used the Umarex 3-9X40 scope that came in the package. I’ll talk about the scope and mounts first.

The scope is a variable with parallax adjustment from 10 yards to infinity. It features a duplex reticle and comes with 2-piece Weaver rings that have 4 screws per cap. The top of the rifle has a Picatinny adapter clamped on the 11mm dovetails that are cut directly into the spring tube, so the scope rings mounted quickly.

Today is the start of accuracy testing for the Octane combo air rifle, and I’m going to make some changes. For starters, I’m going to give you the summary now. The Octane is a smooth-shooting, accurate air rifle. It’s everything the manufacturer wants it to be, and a couple of things they probably didn’t think about, on top of that. The rest of this report will justify and explain my summary.

Another thing, the Octane is different from any gas spring I’ve ever tested. Gas springs always fire fast, as in instantaneously. When the sear releases, the shot is over, and you usually know it from the sharp crack of sound and the painful slap to your cheek. The Octane fires slowly in comparison. There’s a lot of forward recoil and almost no vibration, and the discharge is very quiet, as I noted in part 2. I attribute this behavior to the Reaxis gas-spring design that’s reversed from the norm, and to the SilencAir silencer on the muzzle. Both apparently work as advertised.

Just a word
Befoere I get started with today’s report, I want to say something about what happened this weekend. Friday’s airsoft report got a lot of comments. Among them are several questions about the technology of the guns. And some admissions that people didn’t think much of airsoft before they tried it, then they found their opinions changed drastically. That also happened to me, so I can relate to it.

But all you who don’t care for the subject don’t need to worry. This isn’t going to become an airsoft blog. I will continue to report on it at a low level, but I know this is an airgun blog, and that’s not going to change. I want to assure the readers for whom the subject of airsoft is not welcome that we are still going to talk about pellet guns and BBs guns for the most part. I will write a few reports on airsoft now and then, and I trust they won’t upset you too much.

Octane combo from Umarex: Part 1

Here’s another new air rifle from Umarex USA. The Octane combo is a breakbarrel air rifle powered by a gas spring. Umarex calls their gas spring the Reaxis gas piston. That title Reaxis signifies that the gas spring unit is mouned in reverse of what’s normal. Instead of the heavier piston going forward with each shot…what would be the tail end of most gas springs…is where the piston seal is mounted. That lowers the reaction mass, which lowers the recoil felt by the shooter. Whether or not it works as advertised is something I’ll test and report.

2013 SHOT Show: Part 3

The SHOT Show is not a gun show — though that is what many attendees call it, and the mainstream media that doesn’t attend also calls it that. Instead, it’s a happening — to use a 1960′s term. Or it’s a Middle Eastern open market. The big booths house the recognized names like Colt, Winchester and Crosman. Their booths are two stories tall with signs hanging from the ceiling that you could see a mile away if there weren’t other signs hanging in front of them.

But the real drama of the show isn’t at those booths. People already know what to expect in those places. It’s the little out-of-the-way booths hugging the walls that have the surprises. I always set aside some time just to cruise the aisles, looking for some rocks to turn over.
