Sprinco or colt extractor springs?

[Jstud220]

I started using Sprinco 5 coil springs in all of my bolts about 6 months ago after changing out an old extractor spring. So far they have held up great and worked as advertised. Lately I’ve been coming across some guys who don’t seem to found of them.

What’s your thoughts? Worth it or should I just switch to colt gold extractor springs?

I'm pretty sure you're not going to go wrong with either one. The theoretical advantage of Sprinco is they're supposed to outlast the Colt springs by a million rounds or so, but who knows? Sprinco works fine, just make sure, if you're around salt water, that you keep it oiled and you check for corrosion.

I have always used the Colts and even if sprinco did last longer, I never had issues with colt vs what I read on them from people who had. I will stick with them vs marketing wank.

It would be interesting if there were some type of definitive tests that could be conducted to settle debates like this. There have been a few industry professionals on here on both sides of the Colt spring vs the chrome silicon Sprinco version. Including some manufacturers that use the one or the other with positive results.

There's got to be more to it than opinion.

I haven't heard of SOLGW or Sionics having failures or issues with Sprinco nor have I heard of the new Colt spring falling short.

Nothing at all wrong with having spare parts around.

Personally, I am not swapping out that spring in my DPMS carriers until one fails or starts to malfunction.

Just like I am not immediately swapping out the gas tubes (that they made / sourced the guns with) or their firing pins...

I don’t think it’s hype at all I think it’s a quality spring and better than your standard extractor spring. I don’t get why some guys hate on sotar the guy just puts out good information trying to help people and is pretty knowledgeable.

I’m not trying to start a colt fan boy war I’m a fan of colt myself but it seems like most of the people who have anything negative to say about Sprinco haven’t actually used them and are just doing what colt fans do.

Colt springs are the same as what the military has been using for a long time to make extraction reliable in M4s and MK18s.


They are legit springs and work no matter where you source them.

Sprinco extractor springs work fine as well. I like the 4 coil better than the 5.

I know you mentioned this before, but could you refresh my memory as to why you prefer the 4 coil? Was it just because the end are flat ground?
