I'd like to build an A1 type, triangle handguard, retro type that is sort of a sleeper "boomer" at the range.
Anyone know of a big bore barrel that has a FSB - even if I have to use a clamp/set screw type. I'm running out of ideas, if you can't tell. I don't want to stop building stuff - but building the same thing over and over is getting stale.

they would have barrel thickness less than 1/8"
so no is the answer |

Maybe it would be possible? https://www.kakindustry.com/ar-15-parts/upper-parts/barrels/458-socom/16-inch/contract-458-16-inch-carbine-melonite-barrel Is there any real reason I shouldn't be able to use a barrel like this - a set screw FSB - A triangle end cap, etc? |

Maybe I'll do a dissipator... That way the FSB is up front, with set screw, for show and to hold the handguard - with a hidden low pro gas block further back...
Hmmm... |

Set screw FSB?  Or - I guess you could tap the vertical hole up through under the sling point and put one in there on an undrilled one. |

I think that's what I'm going to do. Dissy type A1 rig.
I'll let you know how it works out. I guess the answer is, no one makes one - so I'm going to try.

Here's a couple of retro looking ones I built. I'm planning on another A1, triangle handguard type for the .450. I used the RRA entry A2 stock on these - I love the length. I'm a nose to charging handle kind of guy - so that compact design really works for me. This is an older pic, as the bottom one now has a Rambo type Lone Star forend. |

I got a .936 set screw FSB from blackethorne for my .50 dissapator. https://www.AR15.Com/media/mediaFiles/181809/3BF8C628-1691-4DA7-839A-22FDE663119D_jpeg-704445.JPG That's what I'm talking about. Did you tap the gas hole in the FSB and secure the triangle handguard cap to it with a bolt, or is it just pinched up there between the FSB and the handguards? |

Cool. Thanks. That's what I was thinking. You don't happen to remember the size you used?

I swapped the trigger guard back out for a standard one. That other one is just too big.
