SCAR Minimalist Rail lightweight forend

Not being negative about your product at all it looks really sharp, but could you highlight what makes this a superior option vs something like Midwest Industries, a Mrex or a Lancer Systems set up or even a PMM short mlok extension?

Those are all excellent products, so I would never claim superiority since every design has trade-offs. The SMR being a "minimalist" design is just more focused on ergonomics, weight reduction, and a streamlined profile as priorities.

If you were to compare side-by-side with the other common aluminum forend options you would find that the equivalent SMR is typically narrower, has a smaller grip circumference, a more ergonomic shape, is lighter, and is the only one that completely streamlines the receiver side hardware.

It's not any one of these individual measurement that makes the biggest difference, but the combination of all these features into a single design that really changes the handling of the SCAR. The "blocky" and front heavy feeling of the SCAR is eliminated which is immediately apparent the first time you pick it up.

You can find some interesting photos comparing these measurements with the OE SCAR forend here: SMR-11 Forend FDE - Rego Systems

Thank you for the good questions!

This looks awesome! Is there a variant that works with a 10” SCAR 16 barrel?

Yes! The SMR-9 was designed specifically for 10" barrels. Here is my SBR'd 16S with the factory 10" barrel and the SMR-9 in Black.

Great minds think alike. Here's how I did my version of the idea before Rego came along. I think I like Rego's better though. I had to source the screws, remove the inner support and nuts, and trim up some grip tape to fit.

Great looking 17 @Kansas boy! Yes you would not believe the time and effort I have into designing, manufacturing, revising, and testing just the flush fit receiver hardware. But once I got the idea for a smooth sided receiver I couldn't abandon it. This kit has 11 additional CNC machined components (6 custom screws + 4 custom Delrin bushings + 1 additional horseshoe bridge) just to achieve that. But it results in the narrowest possible forend without any "warts" which was worth it in my opinion.

What’s the point of the 1/2 MLOK slot right past the receiver? I feel like that could’ve been a full MLOK slot like the MREX to make it be utilized for a light mount with a clicky cap.

Are you referring to the slots located at the 2’oclock and 10’oclock positions right by the gas block?

Since the SMR is so narrow there is not enough room in those spots for a full length MLOK slot, as it would prevent you from removing the gas regulator due to how it must be rotated.

So I have designed some MLOK grip panels specifically for those areas to utilize the 1/2 sized slots. They prevent your support hand from contacting the hot gas block, and also serve as a gas deflector, blocking the hot gases that are vented from the gas regulator. It's actually surprising how much gas is vented from that area (especially the left side). I've had it tear up a couple pair of shooting gloves when using a different aftermarket forend that didn't have a gas deflector.

I am working on a light mount that fits in the 2:00/10:00 spots but it’s not completed yet. In the mean time I can take some pictures of different light configurations using some of the other available light mounts on the market.

I had some questions about light setups. So here are a few pictures using Arisaka 300 series scout lights and their mounts to keep everything tucked in nicely.

SMR-9 and a 10" barrel:








SMR-11 and a 14.25" barrel:

@shadowsong43
On my 16S I used the factory 14” barrel and added a .25” spacer before permanently attaching the SiCo flash hider, so mine is basically a 14.25” barrel that ends up at ~16.2" overall with the flash hider.

Here is the SMR-11 with my 14.25" barrel which I think is overall a great fit. The front of the rail ends ~2” behind the base of the flash hider on this setup.




If you like the rail to extend all the way to the barrel shoulder the SMR-13 can also fit depending on your specific barrel length and muzzle device.

SMR-13 + 14.5” barrel: Should be good to go with pretty much any muzzle device.

SMR-13 + 14.25” barrel: Will be close but should clear most common muzzle devices & suppressors (depending on how it attaches). My SiCo SakerK clears by about 0.2” (pictured below).

SMR-13 + 14.0” barrel: Will be very close or potentially too long of a rail. It may not fit with a suppressor (depending on how it attaches) but other muzzle devices might be ok. If you post your setup I can help estimate how it will fit.
