AR-15 recoil ?


February 16, 2009, 06:56 PM
I had a AR-15 back around 1980, then had the M-16 in the service, I now
have a another Colt AR-15, older model like the late 70's, an I put a all new
heavy barrel upper reciever on, ,,,..maybe I'm wrong, but the recoil seems
very soft an slow, like you can feel an almost hear the plunger an spring go
back. Both upper recievers do this, so I thought it would need a new buffer spring,
so bought a new one..I a gun show, but same thing, it just seems
my other AR an military M-16 didn't have this, but can't think what else it is,
except a bad memory on my part...?...anyone have any thoughts on this.

It is not uncommon to hear the buffer spring when the gun fires. You can add some oil to reduce that sound if you want but then it becomes a dirt magnet. My AR makes that noise too. I've never served in the military or fired an M16, but I know amongst civilians the noise is common.

If you are just talking about being able to hear the buffer spring, with the exception on a few cases where someone has greased their buffer tube, every M16/AR15 I've ever shot has going "sproing!" when shot. This includes "military" versions.

Every M16 I fired in the marines had a very prominent "sproing" sound when shot. Kind of vibrates your cheek bone. My LBC .204 AR does the same thing just not as bad.

Yeah the sproing is very common - it's mainly the vibration coming through your earmuff. Much less noticeable to me when using low profile electronic muffs. As for the recoil, the heavy barreled upper is probably helping to mask the recoil a bit, as an M-16A1 upper would be quite a bit lighter.

The Sproing is greatly reduced by a collapsible stock. I don't notice it with my M4Socom or my Magpul MOE stock, but with the A2 stock it was quite annoying.

The "sproing" is common to all ARs. The softer felt recoil is due to the weight of the heavy barrel.

welcome back to the AR platform , they all do that , its the intent , and it works well , to reduce recoil and improve accuracy ,

im starting to like the sound , it grows on you much like the ping of the M1garand , and the clack of a kalishnokoff , and the smell of the cloud of blue from a black powder rifle ,

are you using commercial .223 ammo? it's often loaded a little lighter that military spec 5.56 like M193 or M855 and may produce a little softer recoil. The heavy barrel will negate a little bit of the recoil too, just due to having more mass than the gov't profile barrel.

first time i shot my ar i notice that spring sound. although i had hearing protection on, i could hear the spring recoil in the buffertube. it kinda got softer the more i shot it.

Thanks guys, it just seems slower, more than spring sound, now can anyone tell me what length their buffer spring is?...does it matter...?
BECAUSE, my old one measures 12", the newer one is about the same, but a guy I know just told me he has a AR an his spring measures 14"....?
I didn't want to ask to borrow it the next time I shoot so I am wondering if I bought a used spring from the dealer, to replace my old spring....are their different lengths? I wouldn't think so unless maybe for the callaspiable stock....if my spring is old an lost its strength, I'm wondering if the longer newer spring would help?...their has to be a reason they sell new springs right, can anyone measure theirs (the spring )....lets keep this clean!!!!

This is to finish up the Thread I started...I just got another bufferspring, the old one when I pulled the handle back slowly you could hear a lot of noise coming from the spring, with the new one, you couldn't hear it an it was much stiffer to pull back. When firing it, the
spring noise was much lower, an the
action of the bolt was much faster, 100% better, I am surprized I didn't have more jams from the older spring.
Also on a happy note, my son, taught me how to bump fire it, for that full auto waste the ammo feel...its my ammo, my money, so please don't judge was fun.

it was fun
I agree. I bump fire mine on occasion. A complete waste of ammo, but an incredibly fun one:D
