Don’t people replace them for some reason? Like to switch to metal or something? I would think it might be easier to simply pick up another stripped lower for the gun and throw it on there, rather than selling the whole gun and starting over trying to find an early one like yours. But then again, maybe when you combine it with the upper color, that makes more sense than anything else. |

I've heard the hump versions are worth +$1000 on the used market, versus the non-hump ones.

Midwest Gun Works has 2 FN Three Prong Flash Hiders listed on their website, one listed as "FN SCAR 17 3 Prong European Flash Hider" for $59 and one listed as "FN SCAR 17 3-Prong Flash Hider w/ Suppressor Mount" for $99.
What is the difference between these models? And is either more clone correct for a MK17? https://www.midwestgunworks.com/page/mgwi/prod/FNSCAR17EU https://www.midwestgunworks.com/page/mgwi/prod/3181380110 |

For the SCAR barrels, these work: Tangodown SCAR Armorer Block Set The MK20/20S has a very different barrel. Much thicker profile and a slightly different gas block mounting arrangement versus the standard SCAR. I haven't tried to take off the bottom rail to see if the SCAR blocks work or not. From just looking at them, it appears that there's a difference in the gas block where it would fit in the barrel block. Maybe clamping the barrel using just barrel vice blocks would work? The barrel extension has two flat surfaces where the three rear mounting screws go, and I would assume that the torque on that is much greater than whatever FN does for the flash hider. For my own question, I want to swap the flash hider for a Surefire muzzle device so I can use my can, and a preliminary try with a wrench finds that it is very, very, tight.

Quote HistoryOriginally Posted By thatguywiththeak: If I have time this week I'll try to take pics of all of the above next to each other as the pics in the links you sent look like they are using the ECP FH as a stock photo. But yeah that's the basic gist of it. If you want to be "correct" for a given time period or config then I'd use one of them. If I'm building a gun for pure utility or perhaps even musing on what a mod 1 might look like? Well the surefire would be a safe direction to head. |

Quote HistoryOriginally Posted By thatguywiththeak:
The focus for the platform very generally seems to be Surefire, and that is driven by several factors not the least of which the fact they make great cans that work well with SCAR, SOCOM has a preference for them because they check many of the boxes (size, weight, durability), and they working relationship between companies is excellent. Without being super cryptic, I suspect that you will see a lot more Surefire stuff used on the platform as a whole to include 20. |

From where I sit I'd say it's a safe bet you will see Surefire continuing to get contracts on future applications to include SCAR given the quality of their stuff and the popularity but I dont work at surefire. But reading between the lines it should be telling to see surefire muzzle devices on new configs of guns at shows recently, FN and other wise. |

They've surfaced in photos before and one even made it to auction not too long ago. Apparently this stock was a short lived interim solution to the latch breakage issue that simply removed the folding feature altogether. FN eventually revised the geometry of the stock folding button by increasing the radius of its locking teeth, thereby reducing the potential of them to sheer off when snapped shut. These new latches are distinguished by their FDE coloration, as opposed to the previously black buttons which can still be seen in use at the bottom of CD's picture.
