Anyone with a Para want to show how the flash hider is welded on to the barrel? Is it a simple tack weld that can be cut easily or a more involved process? Thanks Eta: Thanks to Ecco machine, I found this 9/16x24 to 1/2x28 adapter. https://www.thesilencerstore.com/product-p/ad-ar-004lh.htm

I also have a 300BLK barrel in process… Eta: here’s the one I just bought:

 https://www.thefirearmblog.com/blog/2022/11/05/five-challenges-beltfed-rifle-suppressor/ I must have got a pre-upgrade version. My trigger pull is long but feels like about 5-6lbs. |

Shot the 249s in the 2gun this weekend for fun and it still is one of my favorites. It also looks way good on the ride home in my FJ80 series with the night mode lighting.  Attached File |

Saw you said you got yours down to 9 pounds... That almost hurts me to say out loud: down to 9 pounds.

After the part sat at the machinist's shop for many months, I retrieved it for fear it might become lost. I informed him that I would be more than happy to bring it back when he was caught up and ready to begin production. I never heard back. |

What accessories should I be looking to get? Attached File You'll need the improved (tubular) bipod if you want to run a VFG (or anything on the bottom of the RAS) and still be able to fold the bipod aft. MK46 barrel if you want a lightweight (SBR) barrel. If you can find a MK46 bipod, they're lighter weight, but rarely come up for sale. The MK46 fixed stock is like an M249 stock, but just has a synthetic butt plate instead of the aluminum and steel "shoulder thing that goes up" so the MK46 version is more comfortable. The M192 tripod, if you hate money. |
Here are some accessories you can get. Not pictured (I've added since) are FN Minimi barrel assembly, Minimi para stock, SAVIT stock, and an Elcan M134a. |

The semi-auto FCG has holes in the exact same places and the clearance inside is identical. You just need the trigger assembly, sear, and sear spring. (The safety is the same.) (Just look at the semi-auto op rod and it'll be obvious what the difference is.) This is the component you should serialize, since it's technically the "conversion device". Remove the semi-auto firing pin and associated parts, and it's good to go. |
If you have access to original parts, machinery, and $5k-15k to throw at the project, they're all pretty easy, no? They did a good job making it so factory full-auto parts wouldn't drop in and you weren't going to make it happen with a Dremel... Or in the case of the PS90, a butter knife  Anyone have a sling recommendation? I'm torn between the Vickers (https://www.blueforcegear.com/vickers-combat-applications-sling-m249-saw-sling.html) and the Viking (https://www.vikingtactics.com/shop/vtac-wide-padded-sling-upgrade/). Vickers looks purpose built but the VTAC looks higher quality. Anything else that should be considered? |

Vickers looks purpose built but the VTAC looks higher quality. Anything else that should be considered? That's why I chose the Vickers SAW sling. Mine hasn't arrived yet. I also ordered an ITW M.A.S.H. Hook (1.25") from EmdomUSA like Vickers used in the promo video (since the BFG wire loop stuff uses a polymer coating which can warp/melt). I did get the BFG Belt Fed Loop for the rear attachment, just so I can easily swap stocks. |

I ended up going with the VTAC! I've only owned one BFG sling and wasn't impressed. The Nomex sounds interesting but I'll see how the VTAC does first. We're shooting 200 rounds at a time and either switching barrels in-between or cooling everything entirely. The receiver has gotten warm to the touch but never hot enough that I'd be concerned about the sling... No more so than like a suppressor on a short barrel at least which hasn't posed a problem yet. Those ITW Mash Hooks look perfect, though! Grabbing two of those! |

Originally Posted By Ehtacs: The receiver has gotten warm to the touch but never hot enough that I'd be concerned about the sling... No more so than like a suppressor on a short barrel at least which hasn't posed a problem yet. Haven't seen any slings melted in-person, but I'm sure somebody has ruined one. Full auto SAWs get crazy hot if you're practicing stuff like Final Protective Fire, which I don't want to try with my own barrel, but if it happens I do want the sling to function afterwards. Those ITW Mash Hooks look perfect, though! Grabbing two of those! The silencers like Emdom sells can melt and make a mess, but I'm going to try some 1" automotive heat-resistant tubing covers and see if they'll silence it. The first time I saw those MASH Hooks was when NSW was running them on their MK18 Mod 0 carbines, and I didn't know what they were at the time. Very strong retention. Idk if they're still being produced, or if EmdomUSA is just sitting on old stock. Looks like ITW (Illinois Tool Works) got out of the military buckle business in 2012. |
