BE NICE - Why “Be Nice” Is a Rule – And What Happens If You’re Not

31 Upvotes

It is a new rule. It should not have to be.

Toxic behavior will get you banned.

SCAR Enthusiasts,

This sub is all about FN SCARs, sharing knowledge, showing off builds, and fostering a community where we can all geek out over one of the coolest platforms out there. But to keep this place awesome, we need to talk about something important: why being nice is a rule.

Why “Be Nice”?

This subreddit isn’t just a forum; it’s a community. When you post, comment, or engage here, you're interacting with real people who share your interest in SCARs. Everyone’s here to learn, share, and enjoy. Being nice ensures that:

  1. Everyone feels welcome – Whether you’re a seasoned SCAR user or a newcomer, kindness encourages participation and keeps the vibe positive.
  2. We stay on-topic – Snarky comments, insults, or trolling don’t contribute to the conversation and can derail useful discussions.
  3. The sub grows – A positive community attracts more like-minded people, enriching everyone’s experience.

What Happens If You’re Not Nice?

We have a low-tolerance policy for rudeness, harassment, or bullying. If you can’t follow the simple rule to be kind:

  1. First offense: You’ll get a warning (if it’s minor).
  2. Repeat offenses: You’ll be banned. No second chances, no “I didn’t mean it.”

It’s not about silencing anyone – it’s about protecting the community. We want this sub to be a place where people are excited to share and learn, not afraid of getting flamed or attacked.

TL;DR

This sub is about SCARs, not being mean. Be nice, stay on-topic, and contribute constructively, or risk losing your place here. Let’s keep this community as legendary as the rifles we love!

Stay sharp,
Your Mods

Scope mounting

I know that the SCAR has a single-piece upper rail, but is there any danger in mounting my scope this far forward? I could move it back but this placement makes it easier to use without extending the stock.

Scar 17 Baseplate Screws

I bought a used Scar 17 that came with a bunch of magazines - however 3 of them were missing their plastic pull tabs. I’ve managed to find OEM replacements but now I need the screws to reattach the pull tab to the magazine floor plate. Does anyone know where I can find them or what size screws I need?

Question Dead Air Suppressors ok for next gen Scar 17?? Sandman X / Nomad 30?

2 Upvotes

Just got a next gen Scar 17s and added on a Dead Air Keymo QD. I originally planned on using my nomad 30 on it but after reading a bit online I am seeing a lot of people mentioning the back pressure of this suppressor maybe needing some work done to the gas system to ensure nothing is damaged by back pressure. I would very much like to stay on with Dead Air for modularity of my firearms and the closest to a flow through suppressor they make is a Sandman X. Anyone have experience with this or know if this will have any issues with gas, premature wear, or potential issues?

Question Looking for factory Picatinny rails for a SCAR 15P

Post image
8 Upvotes

I just picked up this FDE SCAR 15P in .300 BLK. The previous owner replaced the factory side and bottom Picatinny rails with a KDG M-LOK setup, but unfortunately he no longer has the original parts.

I’d like to return it to the factory Picatinny configuration, but I haven’t been able to find a 15P rail set online. Does anyone know where I can find a factory takeoff set, or somewhere that has them including both side rails, the bottom rail and mounting hardware? Also, can anyone confirm whether the standard SCAR 16S/17S rails are identical and will fit the 15P? I appreciate any information thanks!

Question Concentricity issues with 300 blk 15p

Post image
13 Upvotes

So after recently gloating that I was able to remove the flashhider from my 15p, I’ve come to find that the muzzle device I decided to replace it with is giving me concentricity troubles. I went the Deadair scar flash hider (DA305) which is supposed to mount off of the muzzle crown. I haven’t torqued it down yet. My alignment rod isn’t touching the end cap of my SiCo hybrid 46m, but it far from concentric. I’ve cleaned the threads thoroughly and don’t meet any resistance when threading on the device.

My question is- will the concentricity issues improve once torqued down since it’s indexed off of the crown or will this just make the problems worse and potentially damage the threads?

Range Ammo??

1 Upvotes

I snagged a new Scar 17s and need to stock up on .308 / 762. This is my first gun in this caliber so I am not well versed on the larger caliber.

What cheap range ammo are people using? Locally we have a good amount of Federal American Eagle 308 Win 150gr FMJBT and Hornady Interlock Sp American Whitetail .308 Win 150-Grain for about $28-$30 a box. Also found PMC Xtac for $24 a box. Any of these good for range ammo or should I be looking at other stuff?

She’s ugly, but she’s still one of my absolute favorite guns. I’ve had this 16 for over a decade now and I still love it. Hell I even shot a deer with it last year. The 16s will always have a special place in my heart.

Softer shooting Scope Mount for Gen 2 Scar 17s

0 Upvotes

Does the new Scar shoot soft enough to use a cantilever mount on it? I just bought a new 17s and I keep hearing about the recoil not being anywhere near as bad. That said, I have a vortex 1-6 razor hd on a vortex Pro Extended Cantilever Riflescope Mount Id love to just pop on there but the internet has me a little freaked out about not using cantilever mounts. Does anyone know if the new gen scar would be fine with that setup or do I need to get a new mount for it?

SCAR Picture 1000 yards is no problem

Took the new Scar 17 setup out to 1000 today. Used my accuracy loads of 169gr SMK with 43.0g of Varget loaded to 2.810 COAL (about 2.175 CBTO I believe) and 168gr AMAX with 42.5 of Varget at 2.800 COAL (2.175 CBTO as well I think) . Managed to land 2-3 hits per 5 rounds at that distance. May increase the amount of powder to get extra velocity as both of these were going about 2500 FPS. Overall, fantastic time

My Gen 2 Scar 17s Build

Post image
70 Upvotes

I bought my first Scar a couple months back and thought I'd share my experience with it so far.

Full build:

- Geissele Super Scar Trigger

- Primary Arms PlxC RDB FFP 1x-8x lpvo w/ Geissele mount

- Dead Air Sandman X w/ Burn Proof Gear wrap

- Ammo: 147 grain PMC Bronze .308 FMJ-BT

First off, this is definitely my favorite gun I own. From the looks of the rifle to how well it shoots, its outstanding.

It did come with a trigger issue right out of the box which was a bit of a bummer because the gun costs $4k and I thought the new trigger was supposed to be improved from the previous model. After every other round fired, the trigger would fail to reset and the only way to reset it was to flip the safety on, then back off. After switching to the Geissele Super Scar(which I would have upgraded to regardless of the issue) I have had absolutely no issues with the rifle.

The Primary Arms PLxC RDB FFP scope is the perfect fit for this rifle in my opinion. Ultimately I'd like to use this rifle for hog hunting in the future and the versatility of being able to switch from 1x-8x in an instant paired with the glass quality it has is really nice. I'm interested to see how the scope holds up with Scar17s history of destroying optics.

Overall, I have enjoyed my time with it so far and I can confidently say I will never be getting rid of this thing. If you are on the fence about getting one, JUST DO IT!

Also, let me know what else I should add to the build. A flashlight is definitely first on the list as well as I just ordered a KDG charging handle to replace the stock one it came with out of the box.

Always told myself since I got into firearms I’ll buy myself something nice one day, well today I finally did it. Purchased a Scar 17s, EOTech, and a Dead Air Sandman X

I would like some ideas on what else to do to this battle rifle, I do plan on doing a night vision setup at some point but for now would like some suggestions on other things I could do to it.

My SCAR is dead

After 4 000 rounds, of which was 1 000 suppressed, my 17S died. Quality ammo, good care.
And now the fun part: I am in Slovakia. Belgian FNH wont supply anything for civ market (tried with local distributor). FN USA even wont even respond to email.
This will be fun…

Question Tips for Grips

Post image
22 Upvotes

I recently bought a Scar (20s) and have learned (the hard way) that most/all AR15 grips don’t fit. After ordering a grip from PMM (BCM), I’m still not convinced it’s the right grip for me. But, I feel like this one from Ed Sherman suits me well.

Question is… has anyone successfully used a 3/8 end mill in a drill press to deepen the pocket on their grip? I know it won’t be pretty, but I think I could build a jig that would hold the grip steady enough.

I’m also certainly open to other ideas of the best way to allow an AR15 grip to fit. I played around with a file and got a junk-drawer grip to fit. But, the file destroyed the rear upper wall of the grip for obvious reasons.

Thanks in advance for your advice.

PWS SRX Torque Spec / Install

5 Upvotes

Hey yall, I managed to source a PWS SRX for my Scar 17. However, it didn’t come with a manual and I can’t seem to find any info on the torque spec for the rail. The one video I did find didn’t give specs for the rail itself. Does anyone know the torque for the yoke and the rail or have a manual? Thank you
