Hey guys, I am fixing to build a GNS, but I have no idea where to get an AR-15 spring. I know it is removed from another air soft/bb gun, but i don't know which one. Does anyone have an AR-15 spring you are willing to sell, or what would be a good spring to use instead. Thanks in advance! P.S. ( I am almost completed with the plunger, I just need the spring)
Umm.. An AR-15 spring comes from an AR-15 (REAL GUN). Its the buffer spring. From a gun shop the package costs about 30 bucks. You can get a part of one from some dude on Ebay for cheaper but again its only like 1/4 of the whole thing.

What? No no no, every gun shop I have ever asked sold me the buffer/recoil/action spring for $1-$3.Hey guys, I am fixing to build a GNS, but I have no idea where to get an AR-15 spring.

For very similar springs you can order a pack of 5 springs from Mcmaster.com

What?! My local shop are bastards then. But even still Online spring packs i've come across are still mid 20's.
Tho there was more then just the buffer spring so that is probably why. They didn't seem to have the spring alone.
I will also have to check out those Mcmaster springs. Thanks Slug the price is what has kept me from picking one up.

Are those approximately the same strength?What? No no no, every gun shop I have ever asked sold me the buffer/recoil/action spring for $1-$3.

MY KITTEN WALKS ON VELVET FEET
AND MAKES NO SOUND AT ALL;
AND IN THE DOORWAY NIGHTLY SITS
TO WATCH THE DARKNESS FALL
I THINK HE LOVES THE LADY, NIGHT
AND FEELS AKIN TO HER
WHOSE FOOTSTEPS ARE AS STILL AS HIS,
WHOSE TOUCH IS AS SOFT AS FUR
LOIS WEAKLY McKay

Yes. Total compression load is 32lb, wire gauge and coils per inch are very close. Only a slight difference in diameter.Are those approximately the same strength?What? No no no, every gun shop I have ever asked sold me the buffer/recoil/action spring for $1-$3.

Nothing much if the change in size isn't very significant.hey slug, What does the diameter of the spring do? Does it give it more powere or what?

Total compression load strikes me as being really useful if you also know equilibrium length and compressed length, because then you can figure out a couple of things, including the spring constant which will then permit you to approximate when the compression load would be for any arbitrary length of the same spring - that is, say you have an AR-15 spring and you want to cut it to some other length, you can then calculate how much force that length would give you before you ever cut the damn thing - or even purchase it in the first place.

Now my plans for sneaking actual metrics into NerfHaven is underway!
Seriously, though, we can probably demand better metrics for ranges than we do, through some standardization. how useful would that be? I don't honestly know, but at least then we'd all be on the same page as to what constitutes 'shoulder height' and 'level'. (personally, I think we ought to forego that altogether and simply use muzzle velocities, but that brings up the issue of high wind resistance on darts and.. gah. Maybe I spent too long in physics.)
