Making an AR more forgiving
I know with handguns you can use a reduced recoil spring to allow you gun to function with lighter loads. I played around with this a lot when I started reloading. Wouldn't the same be true with the AR buffer spring? I was confused when I read a reduced spring could caused the bolt to short stroke. Would this be due to the bolt opening too soon and allowing gas to escape? I was hoping to drop in a little lighter buffer spring so my gun would run on just about anything. Any advice would be helpful, thanks.

Re: Making an AR more forgiving
Are you trying to reduce felt recoil? Or are you trying to make it cycle with underpowered/underloaded ammo?

Re: Making an AR more forgiving
First off, what is it to begin with, and what won't it shoot?
What carrier, buffer, and spring is in it now? What gas tube length?Jeff Cooper was a huge supporter of gun games, when he was winning them at least...

Re: Making an AR more forgiving
If you're hand loading, start with the minimum recommended load and see if the bolt cycles correctly, if it won't move up in .5 gn increments until it does. If you're not hand loading try the 62 grain Wolf. Personally, I wouldn't mess with the action or buffer.
Secondly, if you want the AR to be more "forgiving" in recoil, add weight to it. If you have a A2 stock you can put lead shot or bullets in the butt stock compartment to add weight.
If you have an M4 collapsible stock, Limb Saver makes a nice rubber recoil pad for them.

Lastly, if none of this will work for you increase your ear protection. Many times it's the loudness of the rifle that makes you feel like it has to much recoil.Toujours prêt

Re: Making an AR more forgiving
I'm not concerned about recoil, I just want the gun to be more reliable. Just an example my Glock will have FTE's on some light target loads with a stock recoil spring, a reduced spring runs almost anything. I just want to know if the same thing can be done with an AR. So in general what would make an AR less likely to short stroke with lighter loads? I have a DPMS that is finickey about what ammo I shoot and I really want to fix this. My other AR I built, has cheap no name upper and it feeds anything.

Re: Making an AR more forgiving
I'm still not sure if I'm following you. Do you want it more "forgiving" (recoil, or... ), or, more "reliable?"
What have you found "UN-reliable" so far?

Re: Making an AR more forgiving
The gun is straight from DPMS. 20 in SS bull barrel on the gun. I haven't checked the chamber. If I buy a reduced recoil spring from DPMS will the gun shoot lighter loads? So does lighter spring = more forgiving gun that shoots lighter loaded ammo. On a pistol I know this works I just want to know if this applies to the AR.

Re: Making an AR more forgiving
I have shot just about everything through mine without issue. 5.56 Lake City to Russian steel case.
No issues through thousands, and thousands of rounds.
I doubt it's in the spring / buffer. I bet the gas port isn't aligned or the gas block, if so equipped; is leaking. The gas tube could have also been pinched during assembly.
Or your reloads are just too light.
Carbine gas systems aren't known for being "under" gassed. They are over gassed to make up for the barrel length, and short gas system. So it shouldn't be a short stroking problem.
Try a liberal application of oil to the bolt carrier as well. Is it a new rifle? What's the round count and the loads you are having problems with?
