bcoy SG That's strange - we do it all the time, remove the buffer spring for cleaning on the M16S1. Not difficult as well.
dork3d SG The buffer spring in the butt can be removed, there's a notch and using a tweezer to depress the notch down and the buffer spring can be removed already... Another thing that need the pros here to ascertain is that the flare suppressor for AR15 and M16 are different...
gary1910 SG The suppressor are screwed on, so not really representative. Becos sometime you do see M-16 with the older suppressor in SAF, maybe the orginal was lost and replaced with the older one.
Shotgun SG Hmmm, btw, there’s this tube above the cauliflower in the upper reciever. It like always covered in carbon , and i tried and could only clean the external. The inside of that tube must be dirty as hell, how is it possible to clean that thing.
SpecOps87 SG I meant not the buffer spring, but the tube which holds the buffer spring.Sorry for not makin it clear at the beginning.
Meia Gisborn SG It just so happens that I'm building an AR15 with a 20" barrel for a good friend this weekend, so I took the opportunity to snap a couple of pictures of the buttstock components. I do not remember if these are similar to those in the M16S1 (after all, I did my NS in the mid-80s ); perhaps someone can chime in and comment: The buffer tube is screwed onto the rear of the lower receiver. The flat spots at the rear are to accommodate a 3/4" wrench used to tighten the tube onto the receiver, or to remove it: Hope that helps!
davechng SG Hi Meia If I remeber, the M16S1 have a shorter buttstock than the A2 buttstopck that you have photographed. they do not use that spacer.. since I am not that big size, usually for my full size M16, I like to mount the A1 buttostock over the A2 becasue its much shorter! DaveC
