While I don't know the actual rail length I would guess neither of. Your proposed barrel lengths. I do know it's relatively easy to cut and rethread a barrel, so I say whatever length gives you enough room beyond the end of the rail that will allow for the chosen muzzle device and can while maintaining a minimal gap is what you want.

Id say the A.R.M.S counts as a fsb, it maintains the classic A frame silhouette, is availible with sling loop and bayonet lug and is attached directly to the barrel. It is also one of only two classic A frame styles that straight cross bolt clamps to barrel vs set screws left on the market. JP is the only other option Im aware of now that Armalite no longer makes theirs. Damn shame too, set screw attachment has been known to be capable of deforming the bore by concentrating stress into a relatively small area and degrading accuracy. A true clamp on, like the A.R.M.S or JP will distribute that clamping force more evenly around the circumference and over a much larger area. Clamp on is where its at for a precision build, taper pinned would be the worst (for precision) due to the pins wedging against the barrel.

Quoted: Looks good. While I can't say I'm doing backflips on the rail selection, it should definitely do the trick for you. (Just my personal preference - not a jab.) What I am impressed with is the low profile of the YHM gas block sight. It looks even lower than the A.R.M.S. 41-B and is almost level with your top rail. How beefy is the profile around where it clamps on? It could be another candidate if someone wanted to do some trimming and tuck it in a rail. Looks pretty slick. View Quote |

Yankee Hill FSB. https://www.AR15.Com/media/mediaFiles/379478/2019-06-22-22-36-13_Crop_jpg-1007102.JPG View Quote Criterion has mentioned measureable (via air gauging) deformation of the bore due to taper pinned fsb/gb and suggests against pointed set screw fsb/gb for the same reasoning. https://m.youtube.com/watch?v=aSi75yrTIKQ It only stands to reason that an attachment method that distributes clamping force or pressure over a larger surface area will minimize those effects in comparison. Heres how I would (imo) rate each attachment method from best to worst (with precision as the intended use). - True clamp on attachment, where clamping force/pressure is distributed evenly around the circumference of the barrel (Armalite fsb, A.R.M.S. fsb, JP fsb, YHM fsb, JP gb, Vltor gb etc.). - Flat point (blunt) set screw attachment, where pressure is applied and concentrated in a relatively (two - four points) small area (Fulton Armory fsb, DEZ fsb, home pinned to set screw fsb conversions, many makes/models of gb) - Conical point (sharp tapered point) set screw attachment, where pressure is applied and concentrated in a relatively (two - four points) small area (too many makes/models to list). - Straight (non taper) pinned fsb/gb attachment. Dependent on the level of lnterference in the fit (necessary to retain the pins), deformation could be minimal to significant. (Gieselle etc.) - Taper pinned fsb/gb attachment. The least likely method to allow migration, but due to the nature of tapered pin attachment also the most likely to cause deformation. Tapered pins literally work on the concept of wedging themselves between components (fsb/gb and barrel). They can impart a considerable amount of force that is certainly capable of causing deformation. |

I still have some cleaning and refinishing to do, but I am very happy to report that my "Dremel-Fu is-a-still strong" (-_-). The KAC M-lok rail sections are the perfect fit and help add a secure base for an IR laser and/or bipod. (I just had to mill them flat on the back.) As for the 41-B, even after trimming the base down, it still would have made contact with the inside of the rail. My relief cuts give it just enough breathing room, but the clamps still don't extend past the belly of the beast. This allows for some rail covers with room to spare. All in all, I'm loving the look with the 41-B at the midlength position. Here's a few mock-ups of the finished product. https://i.imgur.com/Fv6qOo0.jpg https://i.imgur.com/OuzxzE0.jpg https://i.imgur.com/wmjbqIh.jpg https://i.imgur.com/Jl2HBtn.jpg https://i.imgur.com/Qdi4Y9v.jpg https://i.imgur.com/Ma1KqwA.jpg https://i.imgur.com/KPvCQnI.jpg View Quote View All Quotes View All Quotes Quoted:
