Does anyone know if there is a realistic chance of a legal, functioning FRT in the works for the FN M249S?

I've read comments that there are people working on them, but haven't heard anymore details than that.  I had made up my mind to purchase a Lima 6 upper (and most likely still will), but was thinking how nice a FRT would be on a factory M249.

Does anyone know if there are FRT options on the way for the SAW?

I think it was AS Designs that showed a super safety prototype for the M249
Stolen Firearm: Colt AR15, Serial # SP342380, 16" carbine. Stolen in California by Kevin Ayres, and taken to Missouri.

I'm still waiting, credit card in hand.

There are so many teasers for various FRTs right now but very few seem to be panning out in a quick manner. I guess if they were easy everyone would be making one.

I've noticed on their website they have it listed as in development.  I hope they release it soon.  That would be a game changer.

I would assume it's lower on their priority list simply due to the more limited numbers of M249s in consumer hands compared to stuff like PCCs.

I wonder if there will be any challenges with the M249s that are pre or post recall. I am not the expert in this area.  I never sent mine back (actually I have never fired my  gun).  Everyone that sent it back said the trigger pull is horrible now.  I am not sure if an FRT will somehow mitigate that, or would they have to accommodate a pre and post recall M249s in their offerings.  

Regardless, my credit card is waiting :)

On the "Production Status" page of AS Designs website they list the M249 FRT as probably being built around the POST recall, currently available design. They explicitly say "Need to verify if pre-recall models are supported".

My assumption is there are far more post recall M249Ses in the world than there are pre recall now, and if AS can get this FRT on the market I imagine most folks will be buying post recall guns.

And as the owner of a post recall gun, the trigger is very heavy. I've been told the mechanical reason for this is that the new trigger design is literally pushing back on the recoil spring or the stock buffer somehow. So the FRT may be working with this, which might mean the trigger pull will be jarring... but at  that point who cares, accuracy is minute of car door at that point.

AS Designs Production Status

The last update on the M249S FRT was back in December that they were waiting on housing samples.

Judging by how the majority of their "in progress" FRT designs seem to be stuck in various states of awaiting samples, my guess is the hold up is their suppliers.

And M249S is probably a back burner project, if they're prioritizing by how popular a platform is.

Anybody SBR their's yet? And if so where did you engrave? I submitted a Form 1 a couple of days ago and looking at the receiver I'm not really sure where the ideal spot would be.

Thinking right here unless there's a better spot someone knows of:

Anybody using one of these for barrel changes: https://www.urbanertslings.com/m249s-a-gunner-qcb-strap-for-para-full-stock/

Or if not, how are you accomplishing quick barrel changes without using the magazine block?

Can't comment on that item specifically, but I bought an UrbanERT sling like 15 years ago and it is by far the nicest sling I've ever owned.

I like simplicity.  I just put a piece of brass in to prevent the bolt from entering the barrel extension and then only need two hands to barrel swap.

Wow, that is smart!

I use the karate chop method.  I karate chop the charging handle with my right hand, and do all the manipulation with my left.

Same in reverse to seat the barrel.

Your solution seems to be better

2 Interesting things to note from that video, I do not see the typical roll pin behind the safety that is on the factory M249S trigger group...





... but it is obviously a semi auto receiver due to the relief in the trigger pack at the rear takedown pin.

Secondly I cannot see his trigger finger moving in the video, even on super slow replay speeds. That tells me this new trigger pack may have found a way to eliminate the gorilla trigger pull the post recall guns have.

Or this is just a post sample conversion machine gun.

EDIT: For comparison, the trigger group in the AS Designs video clearly still has the roll pin behind the safety:



And you can easily and clearly see the shooter's trigger finger moving with each reset.

If that is the case then it implies that that YouTube video by Flat Creek is ghost clothes... aka boo sheet.

The top ones is an open bolt, the second one, with the white trigger frame is not.

They also said it wouldn’t be before the end of the year in one of their other FRT threads. They posted that the day after I bought my FDE Para.

Do you have a link? I asked them late last week in a insta post of theirs and they said after they drop the ARHK the M249 will be the next one up.

In case you have not yet taken any action a proposed rule by ATF, 1140-AA70, if adopted will eliminate the need for SBR or SBS engraving; it will allow use of the original manufacturer info.

That hasn’t been allowed for a few years now.

Hopefully they’ll eliminate the requirement altogether.
You can still file now. It doesn’t need to be engraved until it’s made.
