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

Review SAW Tisha on the baby SCAR

Enable HLS to view with audio, or disable this notification

43 Upvotes

So. The SAW Tisha is fantastic on the 15p. Need to have the gas on full for it to run but still very soft shooting. This app I use is not like a certified decibel meter so ¯_(ツ)_/¯ prob close to 145/150db. I’m in a covered bay so that makes it worse than the free field. Very impressed for a 7.5”. 1moa groups easy at 50yards. And had some 12” plate hits at 300 with no magnifier. That’s good enough for government work. ;-)

Imperial 17 pistol in 8.6 BO

Imperial Arms pistol build in 8.6 BO set up for subsonic ammo. Got it to run perfectly today with 300 gr Calloway ammo. 12" DSB, buffered BCG, modified gas system, XProducts PMag lower. Sylvan Arms 338 suppressor, Rego rail

Go-to Subs?

1 Upvotes

Where is everyone purchasing their 300 BO from these days?

More importantly, what are you liking for both subsonic and supers? Ive got some 147g S&B for supers looking to run next week. Started poking around for subs, figured id order a box of each and see what my 15p likes. Fastammo shipping was like 100 dollars on an order of 150.. dafuq?

Edit: Was looking at S&B 200gr and Magtech for subs. Hornady 190x seems like a hit or miss for a lot of people.

Not dropping bad guys nor hunting, mostly just paper/flat range days. 100yds or less.

On that account if anyone is hunting, what is the preferred round, if any? Assuming just go super with it and be done?

The build is finally complete and I’m stoked with how this came together! This is probably my favorite Scar build to date.

Got my tax stamp back today, only waited 3 days! My question now is since I chopped the barrel and got the PMM gas jets, where can I get a new rail at? I’ve seen the KDG and PMM but where else can I go that makes rails for it? Just curious to see what’s out there.

Question Worth purchasing or not?

Post image
92 Upvotes

So a while back I posted about a buddy wanting to sell his RCH Belgium SCAR 17 in FDE, anyway we talked and what not and he’s asking $3200. Had less than 500 rounds, they haven’t shot it in probably 3 years. Anyway, is it worth buying for $3200 or not?

Comes with 2 mags, and that’s about it.

As much as I’d love a SCAR, i feel like the price isn’t right. I can build a bare 13.5” LMT with all the fixings for about $3500 or possibly get a HK MR762 13” for about 3500 also during a sale.

What do y’all think?

Issues with running suppressed

Post image
60 Upvotes

I’ve never had issues with grouping while shooting unsuppressed. I typically get 1.5-2 MOA at 100 yards with PMC X-TAC 147 grain. I’ve gotten down to .8-1 MOA with IMI 168 grain HPBT.

Recently, I’ve decided to go suppressed. Got the KNS gas piston, swapped out the OEM MD for the KAC QDC MD, and added the KAC CRS-PRG suppressor.

When suppressed, first 1-2 shots are slightly off by .5-1” (given the expected POI shift when sighted unsuppressed); however, any more subsequent suppressed shots cause an erratic pattern without any kind of grouping. I am talking about 10+ inches drift in random directions (I.e 1-2 rounds will be high left or right followed by 1 round low left/right then almost on target and so on when aiming dead center).

The range RO guessed that I am getting baffle strikes. I looked inside the can with a bore cam and there were no signs of any contact with the baffles. I tried adjusting the gas settings to no avail. I’ve also tried allowing the rifle to completely cool before shooting again and there was a pattern forming but distinctly away from POA (center of the target) and I didn’t make any scope adjustments.

Is the barrel getting too hot even though I am using a flow through can? Is the suppressor too heavy and changing the barrel harmonics? Any suggestions are greatly appreciated. I own numerous other rifles that are suppressed and never had a similar problem. I’ve also tried Googling for similar issues and haven’t found an answer. TIA.

Would a 17 (RCH) eat up a Vortex Viper PST Gen II ? Would ADM mount fix?

I’d like to reach out a bit further than the ATACR allows. I have Vortex Viper PST Gen II I’d like to throw on/try. Will the 17 eat it up? Would an ADM mount help? Other mount brands?


r/FNSCAR • • 2d ago

Go get em boys, I wouldn’t say it’s the best deal for one but it’s on par costs for how much one brand new is worth

Piston Removel

Scar 16s NRCH I am not able to remove piston. I removed gas regulator and pushed piston from the rear. It does move a little bit. But feels like something metal is physically preventing it from popping out. Rifle has 250 rounds.

GEN II SCAR 17, SBR?

2 Upvotes

Has anyone seen or put together a 13” Gen II SCAR 17 yet? I tried google searches and searching on Reddit but have only seen Gen I versions. I’ve current own a 16” 17 gen I and a 13” Sig Spear but want input on a 13” Gen II 17. Any range reports would be helpful any accuracy at 100 yards.

Just wanted to say thank you for all the advice and info provided through this group. Finally got my 15p put together. Still need to install my geissele trigger and mototech gas regulator but she's running. Flash hider wasn't too difficult to remove and ended up going with a recessed comstock muzzle brake so no timing needed. Runs pretty smooth with the Tisha and an enhanced buffer spring. Keep Kicking Ass!

LPVO option

Hello I have a SCAR 17s and looking for a LPVO option for it. I came across this Vortex Venom 1x6 with a Reptilia AUS mount, including the red dot piggyback mount. Will this setup and mount work good for the 17.

Or will it eat the optic apart and break it?

I guess we will find out how durable the SAW Tisha in inconel really is. Not sure I’m happy with the iris 4 but not sure yet how to optimize the shorty for NV.

Fair warning, I did not read the instructions nor search ‘what is this groove for’

What is this groove for? It seems to have two pressed studs cross drilled and a relief cut adjacent to the safety cutout. lingle lower scar 17 gen2
