M4 Carrier Plunger spring WASHER (can’t find)

[x143x]

Hello

I recently cleaned my new M4 Tactical LE (11733) and the carrier plunger and spring came out. Thank God I was able to find the little washer that holds the spring in. I immediately went online and attempted to purchase some more of these but I come to find that no everyone’s trigger assembly has this. I contacted FFT and he said that a bunch of people have asked but that he has not ever seen one. Does anyone know what this part number is? Why some don’t have it? I found a video on you tube that shows someone disassembling a trigger with this washer but all the photos I see online show the plunger just resting on the housing. Does anyone know??

I don't know. Mine has that washer. But I checked Numrich and Midwest Gun Works and that washer doesn't even show up on the schematics.

When was your M4 manufactured? 

My "guess" the new model M4 guns use the same spring plunger washer as the M2...but that is just a suspicion on my part https://www.midwestgunworks.com/benelli-m2/washer.html

My well used M2 has a washer from a hardware store collection after I lost the original part late one night. Thousands of rounds later I've never seen the need to replace it.

Mine was manufactured in 2021. Came with the polymer handguard. What you say makes sense and the one you linked looks the same. To the OP I'd just take it to the hardware store and match it up for spares.

I believe the washer is only for the polymer trigger housings.
