Magpul MOE SL Mid length handguard

[scooter22]

This is disappointing.

I feel like BCM is the most prolific mid-length around, and both of mine with FSB use the triangle cap.

I wanted one for my Kino

I'd be willing to bet PSA has a stronger hold on the mid-length market. I don't know if they use round end caps, but I wouldn't be surprised if they were a factor in Magpul's decision to go round or triangular.

Yeah, the SL is such a massive improvement over the original, it's hard to explain if someone hasn't held them. I had the Carbine SL on a rifle for awhile, and it's about as perfect as I think a drop-in polymer handguard could be. Don't be afraid to post up a quick review of the B5, I don't see much mention of it at all, and was wondering if it's a decent handguard.

Yeah, I agree. It's got all the features I want, is slimmer, and is an improvement in every way. I'm bummed about not being able to use it.

I kinda expect to be disappointed by the B5 on a comparative basis to the SL, but we'll see. The wife just NEEDS something smaller in diameter than the original MOE handguards. She can't pool cue the original MOE against a barrier... Just too big.

I had a PSA 14.7" mid a while back. It had a triangle handguard cap as well. That was bought back in early 2012.

Does it look like there's a way to mod the handguard to fit triangle caps?

Thats really disappointing. I was under the impression that triangle end caps were the correct one to be used on a mid-length system. What companies are using round ones ?

This link from the TOS has the reasons Magpul decided to use the round handguard end cap with the middy SL handguards. Page 4 and 5. It is what it is. http://www.ar15.com/forums/t_2_124/2...ndguards_.html

I guess it's possible, but I'd worry more about having it "fit", but be just as loose as the original MOE.

Biggy, thank you for posting that. You're right, it is what it is.

EDIT: having read the entire thread and Magpul's response, there will be no triangle handguard version. They have made a wager that i hope pays off for them. They decided to make the SL mold in a fashion that excludes triangle handguards for the midlength version. I doubt they'll have that luxury with the rifle length version, as I've never seen a round handguard cap on a rifle length gas gun.

It is what it is, as Magpul has chosen to not accommodate the triangle handguard in their mold. That's life. But, it makes it difficult for me to understand how a "drop-in" part can still require punching off a taper pinned FSB to replace a handguard cap. That's not drop-in, in my book. Still, it's a superior handguard to the original MOE and I do wish it would have fit my wife's upper. Sh*t happens. Time to deal.

I'll update here on my basic impressions of the B5 Systems keymod handguard when they arrive. Ordered from SKD Tac. $36 shipped.

I ended up ordering the B5 Systems keymod handguard. I would have preferred the MOE SL, but the B5 works with the triangle handguard cap. MOE SL is up on the EE with all my IWC accessories. Somebody is going to get a solid deal on that. Oh well.

Here is a B5 Keymod on a BCM upper I put together last week. The bottom corners of the triangle stick out.
