Amazing!

The sh..., stuff one learns about guns that are the absolute hotness with huge fan followings and yet remain locked in the dirty little secrets box until,

“Hey, I just got this new gun that everyone’s talking about, but in the fine print in Swahili on a sheet that was under the Styrofoam it says it won’t work unless lubricated with unicorn tears, and will blow up if you use oil. That can’t be right, can it?”

“Oh, yeah, it’s always been like that. But it’s a great gun.”

Also, they kill optics with the recoil impulse (specifically the 17S).

That problem has mostly been addressed, but if you buy any scope/red dot mounts, read up or ask the vendor if they're "SCAR Rated" as when they were released the bolt carrier slamming into the receiver would bugger up scope glass and red dot electronics at both ends of the price spectrum.

You're definitely gonna hate it,best to send it to one of us for disposal but seriously, congrats. I have wanted one of those since they first came out but the prices have scared me away.

First I don't get the issue on FN warranty and a suppressor. They exclude modifying the firearm. That would happen to include any modification but you don't hear about the fact that the geissle trigger also voids the warranty.
But so does almost everyone other mfg. Look at Sig..."This limited warranty is null and void if ... any alteration, including of a cosmetic nature, has been performed on the firearm."

Second, the SCAR is as good as it gets as a suppressor host. None of the problems of about what size is my gas port, or getting a gas reducing gas tube or a new modified gas valve. It has an internal replaceable gas port with a huge range of sizes available. Unscrew it, put in what size you need for your configuration and be happy. That's in addition to an externally adjustable gas valve.

I've never shot a SCAR, but I'm curious...if the action of the bolt cycling is that hard on optics, what is the felt recoil like?

Oddly enough, not bad

Definitely softer shooting than the LMT MWS and AR10 builds I have shot. The Tavor 7 is an even softer shooter, by a noticeable margin.

There are reports that the SCAR's recoil impulse somewhat mimics that of a springer air rifle -- springers are notorious for being hard on poorly-designed optics. From the little I've shot SCARs, I don't find the SCAR recoil all that odd. I find that my AR10s have smoother recoil pulses than SCARs, but it's likely splitting hairs.

I think there's more meat in some slow motion videos of the SCAR 17 while cycling. The ones I saw revealed that the SCAR's upper receiver has a boatload more flex during recoil than an AR10. If an optic is mounted to the receiver using two separate rings (think many bolt action hunting rifles), then the optic flexes with the receiver. I suspect that a beefy one-piece optic mount stiffens the upper receiver enough that scope tube flex is minimized, and most quality scopes won't have issues on a SCAR 17.

Nice rifle. Geissele was a must on mine, or shooting sight, or Timney trigger. Angled charging handle is helpful when running optics. Magpul safety levers are helpful. I like a larger grip but your preference may differ. You’re going to love this rifle. Amazingly light and accurate. Don’t be tempted to put a metal stock adapter on it. The system needs the polymer to flex or you can egg-out the rear receiver screws. The OEM brake is very effective but very obnoxious as noted above. I put the AAC MITER 51T on mine for looks mostly.

UPDATE
Mini range report
Went out Sunday for a quick range trip
Threw an Aimpoint Pro I had in the safe on it just something on it
Me and the son ran a couple mags each through it

Wow!

I have a shot a few AR10s and a sig 716 over the years, but thing is next level nice, I see why you rarely see them for sale on the used market

The son is a Marine reservist (infsntry) and was suprised by the weight, or lack thereof.
I thought it was a very soft shooter in 308 as well.
We were running some CBC M80, and juts shooting 25-50 yds with the red dot.

I’m not stingy when buying glass, but some of the LPVO in the 1-8/10 range are pricey, anyone have a suggestion under $2k in the 1-6 range ?

The son wants the will amended to include this rifle he likes it so much lol.
Maybe I should make him buy the optic, he does get a good discount with Vortex.

Does anyone monitoring this thread have anything to say about the recoil of the SCAR17 with and without the factory muzzle device? There are so many comments online about how the SCAR17 is such a soft shooter; and I agree with them, having shot one myself (with the factory device). However, if a user switches to flash hider, what can he expect?

I don't have experience with the SCAR, in this context, but I have experienced it elsewhere. The SIG 552, for example, does better with a plastic recoil guide rod for the same reason. Some folks say plastic=bad in firearms; not always the case.

Congrats on the new SCAR! Another fellow addict here.

As already mentioned, the Geissele trigger is a great first upgrade.

In my opinion the second most important step is to tune your gas system as it addresses many of the other complaints and concerns with the SCAR (hard on optics, compatibility with suppressors, etc). The ability to do this is one of the best features of the SCAR. Most SCARs come overgassed from the factory when shooting full power ammo. You can purchase a selection of Gas Control Screws from MGW to tune it to your ammo and setup. https://www.midwestgunworks.com/page/mgwi/prod/FNSGCL

This is especially important if you will be running suppressed. I have run my SCARs suppressed for over a decade and have never broken anything. This is due to having a properly tuned gas system. The SCAR has a very heavy BCG when compared with an AR15, so if it's overgassed this is a lot of mass moving very quickly.

Next I would look at forend upgrades. Having a forend that improves ergonomics and also saves weight completely changes how the SCAR feels and handles. After years of being unsatisfied with the other aftermarket options I developed my own solution for this. I don't want to derail your thread so the link is in my signature, if you have any questions just let me know.

Yes. I've used a 17s with and without the factory PWS brake. I've tried a YHM Phantom flash hider (indexes on the muzzle), a Surefire Warcomp, and an SF3P. My round counts are not super high though, we are talking 3-400 rounds max on surefire setups with an RC2 can.

The Warcomp is great without a can and shoots very flat and soft on a 17S. With a can, it is a no-go for me because it leaks tons of gas at the top of the locking ring. It took a while to clean all of the fouling off of the upper and handguard from this leakage. The SF3P is much better at sealing off gas with a can, but you do notice increased recoil to an extent.

With a flash hider, the 17s recoil is on par with an AR10 without an adjustable gas system and heavy buffer.

From some of the stuff I have read, if you are indexing on a PMM shoulder ring, you need to check alignment with a graphite rod regularly to make sure. Baffle and end cap strikes suck with a rifle caliber.

I swapped muzzle devices to an OPS inc 30 brake/mount. It runs fine suppressed with the OPs 12th in .30.

For the optics issue, my understanding was that it was the offset, cantilever rings that did it. I mounted my optic in an ADM delta which has rings directly over the mount and I've had no issues.

The stock trigger on mine was actually pretty good however the Gieselle is a worthwhile upgrade still.

My understanding, and I am open to correction, is that the backplate for mounting a buttstock (I don't have a manual in front of me) is designed to be plastic and that a metal one will cause damage to the screws and upper as the backplate goes from flexible to nonflexible with metal. I wonder if they could have used a hydraulic buffer ala B&T.

Its a great gun, I'm quite happy with mine.

I shot the 5.56 version right when they came out many years ago.

The recoil impulse was overall smooth but there was a slightly abrupt moment when the carrier stopped rearward travel.

I would stick a Vortex Razor 1-6 on that thing. They are tough as nails.

So kind of like an MCX (although I don't recall feeling the stop at the end of travel with the Sig)?

I can't really say for sure as I don't think I have ever shot an MCX.

The recoil impulse of the SCAR-L that I shot was definitely different than a DI AR. Not worse, just different. I remember noticing that there was a brief moment where the impulse was a little more pronounced. I assume that is when the carrier is bottoming out at the fully rearward position.

Most of my ARs are tuned with adjustable gas blocks, so when I shoot a standard AR, especially carbine gassed, they feel noticeably harsher. The SCAR, compared to an M4gery, felt smooth overall.

This is correct. There is an aluminum back plate that bolts to the receiver with 4 screws, and which provides the U-shaped interface for the polymer stock to slide onto.

https://www.midwestgunworks.co...mgwi/prod/F142150020

The portion of the stock adapter that the carrier impacts at the rearward end of the stroke is intentionally polymer to absorb some of these impact forces. If you replace this with an aluminum stock adapter then the recoil impulse of the carrier is transmitted directly to the 4 receiver screws thru this back plate. This is why the screws become canted and eventually the receiver holes become oval shaped.

This issue is much more pronounced on the 17S due to the heaver BCG, and is also a bigger issue if the rifle is overgassed from running a high back pressure suppressor without properly tuning the gas system. A well tuned 16S without a suppressor can sometimes get away with an aluminum stock adapter for a while without causing canted screws. But it's recommended to keep a polymer stock adapter, and tune the gas system if running suppressed, to avoid this issue altogether.
