Mid length handguard with FSB

**AAMP84** · 06-23-17, 14:25

I'm throwing together a K.I.S.S. build with a 16 mid length using a fsb. I wanted to use a JP handguard but the length is 9.25", is that too long to work with an fsb?

I measured my midlength with fsb. Looks like it would barely fit, but might depend on tolerance stacking between components.

I know for a fact the Centrurion C4 9" will fit behind and FSB since i had it on a Kino and it is listed at 9.25".

That said, why not the C4 Mid cutout

I don't need picatinny, and I'm trying to keep the handguard slim for when I take my nieces and nephews shooting.

Do you need a free float tube? The Slimline handguards are slim and are long enough to cover the FSB and help protect a stray hand from getting burned

I have the Midwest Gen 2 SS 9.25" on a front sight equipped midlength.

Troy Alpha rail, 9.25" on a mid length with front sight also

I don't need free float, but I would prefer it. I was just trying to verify what the actual length was to fit a mid length with an FSB. Some manufacturers listed their handguards as 9" and some as 9.25".

Thanks fellas

I think the extra quarter inch takes the hand guard cap (or lack there of) into consideration. You'd want 9.25" without it or you will have a noticeable gap (you'll clearly see the gas tube). I think markm had a build that left the cap in place to fill the gap with something.

MistWolf, what brand is that FSB-mounted accessory rail?
