Sprinco springs

[mustangfreek]

Just curious anyone here running any of the Sprinco buffer tube springs? I know this is one of those areas where everyone has an opinion..lol.. Just curious though and no I have not been eating paint chips ..[BD]

Just wondering if anyone is running any and what was your opinion good or bad of them and what was it on etc?

Refer to post 160. Sinner has apparently had more than his fair share of time with them. Especially since that was his replenishing order....

[mustangfreek]

Thanks for the heads up, hope he pops in with his input..as it looks like he is a fan of them..

Been thinking of trying a couple , can't afford the jp captured spring setup, and looking to maybe tame down some of the twang in a rifle or 2 and see if they help soften up the recoil.. I know many variables.. but just looking for some general feedback

Don't expect any change to the sound, at least not in my experience. Also, motion of the gun may be increased because the bolt will go forward faster.

That, and it will be harder on optics and accessories. Think SCAR, but not as bad.
I have found the vltor a5 with milspec spring to be much calmer than the best sprinco and carbine buffer combo I mixed and matched (blue and h). I think the A5 is easier on the weapon, accessories, and is more effective at keeping the gun flat.

Not to stray by much, but I'm happy with the JP tuned spring. It might be hogwash, but to my ear, its not boingy at all, and I'm talking bare spring, not the captured doohickey. Could be my crappy hearing though.... either way, I'm a happy camper! :)

I just got my Sprinco green spring in the mail a couple days ago and hopefully my buffer tube will be here tomorrow so I can shoot on Sunday. I will post here with my thoughts on it after I get some trigger time.

[John Moses]

I run them pretty exclusively. I use a Green spring in my SBR's with an A5 buffer, and since there are few options for Rifle buffers, I used a Green spring in my MK12 to cure afailure to lock on last round. Not only are these springs available in multiple powers, but they outlast a standard spring 10-1.

[Deadwing]

I've got zero experience with Sprinco springs. My guns all run just fine with good old USGI carbine action springs (i get mine from BCM for like $4 or $5/each), so i've never had the need to experiment with anything else. What little fine tuning my guns have needed, i've been able to do by playing with buffer weights so the extra "tunability" the Sprinco springs offer is of little value to me at this point. The other benefit of Sprinco springs, which would be extended service life, is also of little value to me because springs are cheap. I can buy four high quality standard carbine action springs for the cost of one Sprinco spring. All that said, i've never really read anything bad about Sprinco springs. They're not selling snake oil, as their springs are of very high quality and do serve some very practical applications quite well, from what i've read anyway.

Now, the JP captured silent spring is something that interests me since i started shooting 300BLK suppressed. It's funny how i never really paid much attention to the sproingy boingy action spring noise before. [BD]

There's a lot of debate on that. Personally, I've never worn out a mil-spec spring. Further, if we're going to argue minutia such as "5K rounds service life is not enough...because end of the world!", then I'll argue that they are far more prone to rust than a USGI spring, and rust destroys the surface of a spring, which is the most important aspect OF a spring.

[DutyUse]

I've got a green sprinco/spikes t2 in my 12.5 noveske and an A5 Kit in my BCM. I personally like the recoil impulse better in the A5, but nothing to brag about either wau

I'm with ya there. Considering its either ear-pro, or "FKN KA-BLAAAM!" I've never heard this mysterious boing; must be an all-world/suppressed shooter thing. Quit sniveling about boing: you have a silencer, FFS! [:D]

Now that made me recall that video of high-speed, low-drag operators making mario noises with their big scary machine guns!

[John Moses]

It goes far beyond the cost vs a mil spec etc. It has more to do with spring rates, extended vs compressed etc etc. A good spring will have a more consistent spring rate throughout it's length. ...ie the percentage of it's rate doesn't vary between progressively different compressed lengths. This is the reason a rifle buffer or an A5 is so much better. The Springco isn't just a "more expensive spring" it's a "different spring" much like vehicle springs are progressive etc. The OP asked if anyone has had experience with them, and I just offered my experience. At the end of the day, if someone want's to replace their mil-spec buffer springs when they go bad, that is certainly their prerogative. A Mil-spec spring is crap when it goes, and when it goes it degrades more rapidly. As far as rust, that is something that depends on the material of the spring. ie stainless, piano spring, etc etc. The Springco are acyually an AS77 Silicone Chrome spring, and is not going to rust before a Mil-spec spring. In a nutshell the best advantage to a Springco is the consistency of the spring over the life of the spring. I have previously only used the JP springs, and Spikes H2 buffers, until I used an A5 with a springco, and will never use anything else. It's just that much better, and I encourage anyone who hasn't tried it to at least give it a try for themselves and base their opinion on that use.

[Slippers]

I've tried springco springs and didn't notice any difference. Suppressed, not suppressed, correct gas, overgassed rifles. Felt identical. Ejection similar. No reason for me to buy them.

I measure the OAL of my normal colt/bcm springs and when they go below the specified length, I replace them.

Sprinco absolutely rusts easier than a milspec spring. Here is my compare test. Both were inserted in my dishwasher without soap, and it was ran for 1 cycle included heated drying. The milspec did not rust one bit. I even wiped the surface with white paper. No rust.

Well I'll be a sonofbitch.

[mustangfreek]

Thanks for the info fellas..guess I'll just stay with the mil spec stuff for now

[SINNER]

My head hurts from reading this thread.

All the comments about "a sprinco spring made my rifle do xxxx" clearly are misled as to what they are doing. There is no magic spring that will improve a way a weapon runs every time. Sure you can get lucky with most commercial rifles ( more often over gassed than not) by swapping in a heavier spring but just as often there will be little to no improvement.

The reason I have come to run them almost exclusively is really twofold.

One is they offer multiple spring rates. That combined with a good assortment of buffer weights allows you to truly dial in the gas system of a rifle.

Two is consistency. I have laid out multiple springs from well known companies and could not find 2 that were the same length or coil count. Cut down rifle springs, "carbine" springs that were the correct length but had the coil spacing so jacked up the bolt bottomed on the spring before it would lock back and so on. Not even getting into spring rates. Year after year the Sprinco springs are the exact same thing for their given spring rate.

And the highest quality spring stock possible is always a good thing.

The only spring I have ever had fail was a flat wire spring so they are not an option.

As for the rusting comment no product can fix poor maintenance. If a chrome silicon spring is rusting in your buffer tube you had to have neglected to maintain that component because if the entire gun was maintained as the spring was, the other components such as bolt catches, magazine releases and take down pins would be orange with rust. I use a product called Corrosion Block to lightly coat any and all springs in my weapons.

If I had to guess I would say the last 20 weapons I've built have had Sprinco springs and see no reason to change what works so well.

And in regards to the JP captured springs they work well to cut down on noise and that's about it. Even with the outrageous price if they worked better I'd use them. For that kind of coin and only having 3 options with the multi spring set they are not an option unless it's for a weapon running a can shooting subs exclusively. Even on those it's a compromise when it comes to correctly tuning the rifle.

Oh Come on Sinner, it's fun to shoot your guns in the dishwasher.......

I've had AR's rust up over a hard weekend of use. I would rather just eliminate that variable. True, i was shooting Wolf Polyformance, which is mildly corrosive in my experience, but still...

[scojo]

I haven't had any rust issues to speak of, but also live in the Arizona desert, so high humidity is not a major factor. That said, I do keep an oily rag handy to wipe everything down before it gets put away.

[mustangfreek]

Sinner...

....tell us how you really feel.....[BD].....lol

Good info all around

[JGifford]

The next question is...is this increased rebound force of the enhanced sprinco doing your optics any favors...a la SCAR?

[JGifford]

Having to re-visit my opinion, here. Been having functional issues with a dirty weapon and Vltor OEM A5 spring. Swapped in a Sprinco green spring, and while the weapon feels a bit more "punchy", it will 100% always chamber a round when I drop the bolt release, instead of binding. Also tested the Sprinco extractor and ejector spring. They worked as well as the OEM Colt stuff I had been using. I went all sprinco, simply "because". and just keep it lubed. They are more prone to rust, but I have used Sprinco before for thousands of rounds, and well lubed they are fine.

[UWone77]

Based on SINNER's comments, I ordered 2 Sprinco's to try out.

[Naytwan]

I run them in several guns. I originally got mine cause the rifle I got it for was over gassed. With the spring and an H buffer smoothed things out. I run blue springs in my rifles.

[din]

I use green with VLTOR A5s on everything. They are awesome.

[mustangfreek]

Haha...I was thinking of trying one also, as I need a spring for the 16"-300 bo build, thinking the white one, then I could see for myself ..

[SINNER]

What spring rates did you go with?


Haha...I was thinking of trying one also, as I need a spring for the 16"-300 bo build, thinking the white one, then I could see for myself ..

The white one is just a standard spring rate. What is the intended use of the BO? Carbine gas I assume? I would run a blue spring with a H buffer for supers and suppressed subs. If supressed supers are being ran I would likely go with a red spring and a H buffer.

[mustangfreek]

Yes carbine gas. No suppressor.
