I am a certified dumbass and bought Giessele's Rifle Length Super 42 Buffer Spring, when I'm building a carbine length gun. I thought the features this spring offered were pretty cool but I obviously wasn't paying close enough attention. Even more, they say that only their buffer will work with the spring (however, mine seems to fit perfectly fine).
Further being the dumbass I am, I'd rather not sell it off, so do you bros think it's possible to cut the spring to proper carbine length and heat up the end to fit appropriately?

Yes. However, don't know what the purpose is of heating up the end

My only thought there was because the ends of these springs are sort of 'squished' at the ends, I assume for some purpose. Though I don't know if heat could cause some harm.
But is cutting springs an entirely acceptable practice?

Sure, these aren't neonatal neurosurgical instruments

I wouldn’t.  You need to buy the proper spring for the application.

If you don't want to sell it, save it for another gun and buy the correct one.

Primary issue is they don't have this in stock for the typical version

Cutting the spring changes the rate of the action.

Heating a spring [to alter it somehow] basically ruins it. If you are trying to form a spring somehow using heat, you've gone way past the heat tempering level and into ''no more spring'' area.

Yeah, missed that point.

Heat will kill it.

Either save it for a rifle build later down the road, trade bait, or sell it & use the CORRECT spring.

Your ideas to "modify" it are ...  "unwise" (at best)

I would not cut a "stranded-wire spring," which is what that spring is.  I would expect the individual strands to fray apart.

I would not cut any spring, since cutting it changes the rate, the loads at the working heights, and the total elastic energy it contains within the working stroke.  I would buy the correct size spring.

Cutting it and “reheating the end” is a stupid idea. Send it back or sell it on the EE instead doing a bubba job on your rifle.
Shit, man. THIS is $5 right now.

Good advice, and thanks for the heads up at Damage Industries, I like them - good quality folks

the 'ends' of compression springs are 'squished' to spread out the compressed force on the spring face.. Remember, you are trying to dampen the BCG and the buffer.

The spring is 'tensioned' to give specific compression rate and pressure over certain time and distance.

One way to reduce tension / length is to take zip ties and capture a few wraps near the end of the stock, opposite the buffer end.  That will change things and be easy to reverse.
