Improve your FN SCAR With a Geissele Super SCAR Trigger

Hey guys, welcome back. Today I want to talk to you a little bit about Geissele triggers. Geissele makes triggers for a number of different firearms. Mostly they’re noted for their AR-15 triggers but they do make triggers for other firearms, firearms such as the SCAR, which I have here in front of me.

The trigger for the SCAR is called the Super SCAR. It comes in a package like this. They’re not inexpensive, but they are definitely worth the investment. I’m going to put this trigger in my FN Herstal SCAR 16. I already have a Super SCAR on my SCAR 17, which is set up here. I’ll show you first of all what the trigger pull looks like on my 16S before doing the installation.

I’ve got my handy Lyman digital pull gauge here. We’ll get it zeroed out, make sure that’s clear and cocked, hit ready, and let’s see what we get for a trigger pull. The SCARs have decent triggers, some of them. I’ve also seen some with some bad triggers. That one read five pounds, twelve ounces, not too bad for a military trigger.

They are gritty but it’s a usable trigger pull. It’s on par with an AR-15 really. Let me get this to zero here. I’ll do one more. Five pounds six ounces. To give you an idea of what a SCAR or Super SCAR trigger might do for your gun, I’ll come over here to the 17 which already has a Super SCAR installed and do a quick test. It’s a two-stage trigger. You see I just took the slack out.

Now it breaks cleanly, three pounds 15 ounces, zero it out. Do it again. The trigger pull is definitely lighter but what you’ll also notice is first of all, it’s two-stage. It’s a much cleaner, crisper trigger pull, more usable. Three pounds 11 ounces. That’s a fairly light trigger pull but it’s still usable. It’s not like you’re gonna get double taps or anything off the bench.

Sometimes if you get your triggers too light with a semiautomatic rifle, you can actually bump fire it. I’ve had that happen with semiautomatic rifles when shooting off the bench. That’s not too light. This rifle shoots really well. Typically speaking, the better your trigger is, the better your groups are going to be.

If you want to tighten up your groups on a rifle that’s already fairly accurate, putting a better trigger in it can certainly help achieve those tighter grooves. What we’re going to do now is take this Super SCAR trigger and put it into my 16S. You guys may not know this about me but me and tools; we don’t get along so well. I suck with tools.

My camera man is going to put this trigger in. we’ll do a quick collage. I don’t want to go over the entire installation process. That’s not what this video is about. If you do a search here on YouTube, you will find plenty of installation videos that detail the installation of Super SCAR triggers. We’ll show you basically what it looks like and then we’ll do a little bit of shooting with the rifles.

I’ll give you some more commentary and some thoughts on the Super SCAR trigger system. Let’s take a look at it being installed. Before we do the trigger swap let’s fire a group out the rifle using some 69-grain match ammunition from Black Hills. I’m using a Browe BTO. I’m a real big fan of these sights. I love them, bright clear optics.

You will see a full review on this optic coming up here really soon. I think I’ll probably wind up leaving this optic on this particular rifle because it seems to be a great combination. Do a five-shot group. We’ll do a trigger shot—a trigger swap, and then we’ll see what the groups look like afterwards.

Even through this four-power optic at 100 yards, I can see the group. It’s a little bit off center. The rifle was zeroed with M193 Ball. The match ammunition is a little bit off. The point of impact has shifted, but the group’s not that bad. The trigger in my 16S isn’t horrible. Let’s do the trigger swap and see what we’ve gained.

The trigger’s in the SCAR 16S and let’s see what the trigger pull looks like weight wise. You can see that second stage comes in right around two pounds eight ounces and then onto the break, three pounds 15 ounces. Let’s do one more, first stage a little over two pounds, breaks.

That one’s four pounds one ounce. One more. Three pounds 12 ounces. We’re looking at about three pounds 12 ounces on the trigger pull, which is very consistent with what I see out of my 17S and the Geissele trigger that I put in it. Now that we’ve got it installed, let’s do a little bit of shooting, see how it feels.

Now that we have the trigger installed, let’s see what kind of group we can get, and see what that trigger feels like.

I will say that trigger is vastly improved. It will surprise you every time it goes off. Definite improvement. Let’s take a look at the group sizes. Before the Super SCAR installation, this is a five-shot group using the Black Hills 69-grain ammo and we’re looking right at about an inch and one, two, three, four, five eighths, about an inch and five eighths group.

After the installation, we’re looking at about an inch and three eighths, so definite improvement. You’re not seeing a drastic improvement in group sizes. The trigger isn’t horrible or wasn’t horrible in my 16 before the installation of the Super SCAR, but what I will say is—and my camera man will confirm this—before you knew when the gun was going to go off.

I’m just used to shooting cruddy military triggers. After you put the Super SCAR in the gun, it surprises you every time it goes off. It’s a good match-quality trigger. There you have it. It definitely improved the groups a little bit for me. It’ll probably do even better once I shoot a little bit more.
