ARP 072 - The SCAR

Welcome to Episode #072 of the AR-15 Podcast. I’m your host Reed Snyder and with me today are my co-hosts Anthony Hardy and J.W. Ramp. This is the podcast about your favorite black rifle! This show is for you; whether you're building your first AR or you’ve been building ARs for years. There is something we can all do to take our black rifle to the next level. Brownells helps make this show possible.

Don’t forget that Brownells is there for you anytime you make a mistake, like when Jake shoots a take down pin detent across his avocado green linoleum flooring and it skids under the cabinets.

Main Topic: The SCAR


The Special Operations Forces Combat Assault Rifle (SCAR) is a modular rifle made by FN Herstal (FNH) for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consist of two main types. The SCAR-L, for "light", is chambered in the 5.56×45mm NATO cartridge and the SCAR-H, for "heavy", fires 7.62×51mm NATO. Both are available in Long Barrel and Close Quarters Combat variants. Began operational deployment in Apr 2009. First large unit to receive them was the 75th Ranger Regiment. USSOC has cancelled their order of the SCAR-L but will continue buying the SCAR-H with 5.56 conversion kits.


  • Military rifles built by FN Manufacturing in Columbia, South Carolina.
  • Civilian semi-auto versions built-in Herstal, Belgium and imported through Virginia.
  • Lower is polymer, upper is one piece of aluminum (monolithic rail).
  • Tappet closed gas system, like an M1 Carbine.
  • Bolt carrier similar to an HK G36.
  • Folding stock because there’s no buffer tube needed.

16 VS 17

  • Different roles, weights are fairly similar.
  • Mag compatibility.


Cost - Don’t have to pay for a free-floated quadrail or BUIS. Weight (7.3lb 5.56; 7.9lb 7.62) vs Ruger SR-556 (7.4lb) / Ruger SR-762 (8.6lb) Compatibility - Availability/pricing of spare parts; accessories. 17 has replacement lowers to take different mags. Reliability - Much heavier bolt carrier, mass momentum feeds the new round, rather than just spring tension; also slows the firing rate. Longer bolt cam travel gives the round longer time in the chamber before extraction (cools the fired brass when removing from chamber). Every part of the bolt carrier group is beefed up and is also kept away from combustion gasses, keeping things running cool. When shortening the barrel, the gas system all remains the same, no need to bandaid the overgassing issues with different weight buffers. Accuracy - Lower felt recoil, faster firing pin impact A very detailed review from Hootiewho:


While the SCAR-16 is a very nice upgrade to a standard 5.56 AR-15, the platform doesn’t offer the average civilian enough of a step up to justify its almost 2x price premium. When moving up to the .308 platform offered by the SCAR-17, it’s tougher to beat on price and is a very competitive rifle, capable of long-range accuracy.

Listener Feedback:

Arturo C: Hey Reed, When you send in your Garand to Silencer Co. to get threaded for the 7.62 Saker, get one of these and you'll probably be good to go with any 30-06 ammo.

Ported Gas PlugWoodstock36: Hey Guys, Just listened to your last episode on accessories for the MSR, great coverage and review on everything. I am currently running a 4x32 ACOG on my rifle and also recently just purchased a RMR and a pair of Troy DOA BIS in case the ACOG and RMR some how fail, you never know. Anyway, I was thinking of mounting the RMR on a 45 degree mount and then also mounting the BIS on 45 degree mounts. My question has to do with co-witnessing. Can you explain what co-witnessing is, how to set up co-witnessing, and the benefit of doing so. Also you guys recommended some great options for 45 degree mounts for iron sights, do you have any recommendations on a 45 degree mount for the Trijicon RMR? Keep up the good work.

Ramon: Great interview with Silencer CO. I unfortunately still live in the Republic of CA. I am currently looking for employment in WA, UT, and OR, in that order.

When I move and hopefully to a suppressor friendly state I will be starting my stamp collection for both myself and wife. :-)

Joshua Waldron, thank you for the information about silencers. Looks like I have found the company I will purchase my first suppressor when I can.

Another RIFLE build. Yes!!!! I like to submit a request. When doing each segment on the build, please refer to some of the troubles, / mishaps / things that didn't work. What I have fun a lot on YouTube are perfect segments of builds. No problems. And I live in a world that Mr. Murphy lurks around every corner. By providing this information I believe it will benefit some other new builders like myself.

Thank you Brownells, totally awesome. Tim Li: Hey Guys, I bought a complete Delton Sport at a gun show here in CA 8 months ago and, after listening to your podcast, have started my first build. I was going to drop in a ALG trigger but after comparing them to gneisses I noticed they look completely different. After finding this video on YouTube by Bill Geissele it seems like the only real difference is Geissele springs. Are there any other slightly better than mil spec triggers that will not have me breaking the bank that I could compare with ALG?

Thanks for all you do and please enter me into any/all giveaways.
