Muzzle Break - JComp Type98

[fyrfytr]

So I decided to upgrade my A2 birdcage. After some looking I opted to go with the Strike Industries JComp Type98.

Installed real easy...except for my OCD about having the logo centered better.

For everything that I saw about how great it was and how it cut down on drastically on the recoil...I sure didn't feel a change. Maybe I was expecting a lot, maybe I have it installed wrong, maybe I am just crazy.

Anyone have experience with this?

I have one on my AR, it deflects the blast out the sides. Have a buddy shoot it and sit next to them, you will feel the concussion. This break also suppresses flash fairly well.

The free recoil energy of an AR15 with a 55gr bullet at 3000fps calculates out to about 3.0 to 4.0 ft-lbs depending on weight of accessories. My experience has been that I can't tell the difference on my shoulder unless the change of free recoil energy is at least 2.0 ft-lbs.

It's doubtful that any brake will give you a 50% reduction in recoil. However, the brake should redirect the muzzle movement during recoil. Some muzzle brakes will actually push the muzzle of an AR down during recoil. The best designed ones will direct recoil straight back, allowing the sights to remain on target.

I don't use a brake on my AR's because I don't care for the redirected muzzle blast. My hearing is bad enough as is.

I spent a fair amount of time reading about brakes/comps before purchasing one. There's always some level of compromise between muzzle rise, muzzle report and flash suppression. No one muzzle device does all the best. I ended up purchasing a Lantac. Remarkable performance reducing muzzle rise with moderate increase of muzzle report and flash. Very pleased. A bit pricey MSRP of $140. I happened across a sale at Primary Arms for $87.

I have never use a J-Comp 89. Why don't you don't think much of it but you read good reviews? No idea. I'm sure the $20 price is a big attraction. Perhaps it provides less muzzle rise management but does a better job of keeping a lid on flash and muzzle blast than other comps? I noticed that the end of the 89 is open like a typical flash hider.

Never could see much use for putting one on a 223/5.56 considering there isn't hardly any recoil to begin with. Not to mention the muzzle blast it pounds any shooter around you with. Muzzle jumping around that much, might want to hold on to it a little better.

For some of us, there is not much of a choice. Its either go thread protector or brake/comp as flash hiders are illegal, unless you want to register an assault weapon. And that's a whole can of worms.

Plus in some forms of competition, .01's of a second can make a difference in how you place.

The price point was what defiantly a factor for making hat choice, and the reviews of it put it as really the best bang (no pun intended) for the buck...so I pulled the trigger (again, no pun intended). I am not a tactical operator nor do I shoot in a competition setting, I just shoot at a range and have fun with friends so I am not looking for a flash reduction. I know that the .223/5.56 doesn't have a lot of recoil but in a fun setting any reduction of recoil makes for a more fun time at the range. One of the reviews on Primary Arms said "...It's almost like shooting a .22 LR...", now I wasn't looking/expecting something like that...but I (in my limited opinion) didn't think that I had any decrease in recoil. I was shooting outdoors from a bench, so I cannot comment on muzzle rise...but like I said, I shoot for fun so I don't mind taking extra half second to comeback on target before firing again.

Like you, I mainly shoot for fun though I did shoot USPSA for several years. I put a comp on my Sport II because of the laws we have to deal with here in Ca; don't want to go through the RAW route. Didn't expect to feel any change at the shoulder despite the vids online that suggest otherwise, and I was right. The small bore AR just doesn't generate the recoil energy to make any small reductions noticeable.

Yup. "Best bang for the buck" and "For the money" in product reviews is quite common with less than impressive optics as well.

Here are the things I have done with an overgassed 16in carbine to reduce felt recoil and muzzle rise.

* Heavier buffer-- Spikes ST-T2. It made a small maybe kinda sorta difference in felt recoil... eh.

* Adjustable gas block-- Syrac Ordnance. Significantly reduced felt recoil. After installing the Syrac I put back the standard buffer.

* Brake-- Lantac. Significantly reduced muzzle rise.

With the Syrac not bleeding off as much gas, I reckon that can only help the Lantac. Probably not much if any. But can't hurt.

"thread protector or brake/comp as flash hiders are illegal"

Witch makes no sense at all (but we already know that )

I've shot competition and understand how that works both ways too.

I knew the claim of "shooting like my 22LR" was a pie on the sky type of reaction, especially at that price point. I guess I was looking for something to take a little of the edge off when I shoot, and make it more appealing to some of my friends to shoot. I also like not having the A2 birdcage on it as I like things a little different, make my gun more of my own so to say. (why I went with the hexmag versus the pmag)

I do like the idea of tuning the gas at the gas block, how did you decide on the brand? Went to look at it and it looks to have been discontinued.

I got the Syrac because I liked the detent design for the adjustment screw rather than a locknut or setscrew lock design on others I was considering. I hadn't heard Syrac was out of business. I had read that Superlative Arms made what Syrac sold. Did some clicking and it looks like they stopped operating sometime in the last quarter 16? Primary Arms sells a Black Rain Ordnance that looks identical in every way including finish and logo color to Syrac Ordnance.

I've read complaints about the detent system and adjustment screw fouling. Been using mine since 2015 and no issues. But I don't crank on the adjustment screw all the time like some do who shoot suppressed. I've left mine alone after I got it where I wanted... and I guess I'll leave it that way. Another way to avoid an overgassed carbine is to use a mid-length, but I liked the idea of tuning it to what I wanted.

Anyway... there are a ton of adjustable gas blocks on the market to choose from.
