Otter Creek Labs Infinity 7.62

Description

This is going to be a lot of words but hang with me here, it’s worth it.

BYOM – Buy Your Own Mount. This suppressor does not come with a mount, this suppressor does not come with a mount, this suppressor does not come with a mount. If you email me and say “Hey man I just got my infinity out of jail and there’s no mount in the box” I’m going to make fun of you, just keeping it real. We surveyed around 3000 customers and 78% of them said they don’t use the direct thread mounts that usually come in the box with suppressors. They throw it in a parts box to be forgotten or throw it away and buy their own mounting system. So we decided to just not include a direct thread mount with the infinity so we could reduce the cost and you’re not paying for something you’re not going to use. It’s already an expensive suppressor, no need to add to that cost unnecessarily. It is 1.375×24 HUB threaded which is the industry standard universal mounting system. There’s hundreds of combinations of mounts and stuff that work in this suppressor, if you need help picking one out feel free to email us.

Infinity — We decided to call this project Infinity early on because we wanted this to be a suppressor that will last you forever, you can pass down to your grandchildren and it last them forever too. Also because of it’s adjustability and ability to be configured to any host you have. It’s also marks our entry into the low back pressure market. Notice I didn’t say no back pressure, I said lowER back pressure.

We wanted this suppressor to straddle the line of suppressors with zero back pressure that sound like a pipe bomb and suppressors with high back pressure that sound great. There’s no free lunch when it comes to sound suppression. You either have a suppressor that’s loud with zero gas to the face or you have a suppressor that’s quiet with some uncomfortable gas to the face, it just is what it is. We wanted a suppressor that could ride the middle ground line and venture to both sides of the line depending on what the user wanted.

There’s all kinds of fancy marketing words you could come up with for it that will make you sound smart. Hybrid adjustable flow path technology being calculated by a super computer in a lab and optimized by an AI program in real time. Engineers applying echolocation quantum mechanics for the absolute refraction of performance. Don’t forget to throw something about aerospace or secret military teams and operators in there somewhere. But it’s all so generic, predictable, typical, boring and most of all… bullshit.

So let’s cut through the bull shit and get down to the nitty gritty of what this suppressor does and what makes it unique. We knew we wanted it to be 7.62 bore with changeable end caps. We knew we wanted it to have great 7.62 performance but let’s not kid ourselves, 99% of users buying a 7.62 bore suppressor are using it on 5.56 most of the time. So the 5.56 performance also had to be on point. We developed the general sound profile using 7.62 and then further dialed it in and refined it using 5.56 – we made over 100 prototypes in almost 2 years of testing finding just the right combination that does just as good on 5.56 as an actual 5.56 bore suppressor while still offering great 7.62 performance AND works well being vented or unvented.

It has 3 different end caps that come in the box to adjust the back pressure and flow rate based on what host you want to use it on. Additional end caps are available for purchase separately. Other suppressors in the past have tried this idea, adjusting back pressure by changing end caps that allow it to vent from other chambers. But in our opinion they didn’t do a good job – great idea but poor execution. So we wanted to take that idea and make it good and I believe we’ve done that. How we did it is the inside of the infinity is actually divided up into 4 chambers. The first initial expansion chamber vents gas straight off of the muzzle as it enters the suppressor > the second is a high back pressure chamber that holds the gas while allowing a small amount of controlled flow into the third chamber > the third chamber is where gasses coming down the bore and gasses from the high back pressure chamber combine before going into the fourth chamber > the fourth and final chamber is a low back pressure high flow rate zone that moves gasses down the side wall. When you use the vented end cap it’s only venting gasses out of the fourth chamber which allows it to be very balanced. When using the vented end cap the pattern is vent > hold > combine > vent. When using the solid end cap the pattern is vent > hold > combine > hold.

Solid 5.56 end cap (included in box) — The highest back pressure setting for this suppressor. Sound suppression similar to a Polonium or Polonium-K and depending on the host you might need to tune it. BUT if you’re one of those people who don’t care to tune a gun and you want max quiet on your 5.56 rifles this is the end cap you’ll want to use. It offers excellent sound performance and flash reduction. It can also be used on 6mm/243 bolt action rifles.

Vented 7.62 end cap (included in box) — The lowEST back pressure setting for this suppressor. If you are running on a back pressure sensitive 5.56 host or any semi auto 7.62 rifle this is the end cap you want to be using. This end cap is going to be for your MCX, Scar, AR10, Tavor, AK platform guns and over gassed AR15 pattern guns with gas ports so gaped it would make a pornstar blush. Basically any gun or any use case where you want the least amount of back pressure this is the end cap you want to be using.

Solid 7.62 end cap (included in box) — This is the goldilocks end cap, the middle child. It’s right between the other two we just went over. On 5.56 rifles it offers a medium back pressure setting and works great on guns that aren’t gas sensitive but aren’t necessarily tuned either. This is also the end cap you’re going to want to use on 6.5mm, 7mm or 7.62mm bolt guns or subsonic 300 blackout.

Vented 5.56 end cap (available for purchase separately) — This is kind of a niche end cap. It reduces back pressure when compared to the 5.56 solid end cap or 7.62 solid end cap but not as much as the 7.62 vented end cap. If you have a gun where it needs to be a little less back pressure than the 5.56 solid but a little more back pressure than the 7.62 vented this fills that gap. Most users will not need this end cap in our opinion which is why it’s not included.

So there you have it, that’s the end cap system explained and you have an end cap to optimize the suppressor for just about whatever you want to do with it. Changing end caps is quick and easy and comes with a wrench in the box to do it with.

Being made from DMLS 3D printed & heat treated 718 inconel this thing is tough as nails. No barrel length restrictions, no firing schedule restrictions on magazine fed guns. On belt fed 5.56 guns we recommend not exceeding a 300 round solid string of non stop fire without a cool down period. On 7.62 belt fed guns we do not recommend exceeding a 200 round solid string of non stop fire without a cooldown period. If you are running it on a belt fed you need to be using the vented end cap. This suppressor has been tested to the most brutal extremes we can think of and has handled anything we’ve thrown at it. Yea yea yea it’s a little on the “heavy” side, there’s plenty of lightweight less durable options if that’s your thing. But this thing is built to last.
