First off, the negative reviews on this spring are nonsense. It absolutely does fully compress in a carbine tube. If it's not fully compressing, then the issue is the knuckle dragger who installed the spring tried to put a carbine buffer in the tube, not a 308 buffer. Also, if you can't exert the oomph needed to get this spring into the tube, you probably don't have the body mass to take 308 recoil and should stick to 556. Now, the spring is absolutely stuff, and it does require more effort to fit it all in the tube, but once you have it set, it's very smooth and consistent. It feels much better than a traditional piano wire spring. Cost is reasonable for being an upgraded spring, comparables cost even more. Cost to value ratio is stellar. Similar to a Tubb spring in feel and performance.
Pros:
- Cost to performance ratio, good value
Would recommend: Yes

Easy to install. Improves function, in that carrier is lighter, no binding. Waiting to do a final test. Carrier was short cycling.
Would recommend: Yes

I'm not sure if this was packaged wring or has the wrong description, but it is the length of a rifle buffer spring and does not let the gun cycle fully. I will be replacing it very soon and seeing if this fixes my issue.
Would recommend: No

I’ve used several of these springs in different AR’s I’ve built. They’ve always worked great and reliably. I actually installed this latest one in an AR-15 9 mm pistol I built. I can’t say yet how well it works or if it will be too stiff for a 9 mm application but many people say that it’s best to use an AR-10 buffer spring in a 9 mm build, so I’ll have to see if it functions properly. I’m using a 6.5 oz. Buffer so I wanted a stiffer spring in it since I already had the buffer from another build.
Would recommend: Yes

Great spring and very quiet, no more AR "thwang" after every shot. Longer than expected and a little bit harder to install, but excellent all the same

I love the strike industries flat wire springs because I've built like 3 ar builds with them and haven't had any problems cycling. This will be the 4th one I've purchased. Decent price verses paying for a basic spring and a high end spring like the Geisle spring....if thats how you spell it lol
Pros:
- Durable, affordable, functional
Cons:
- can't say anything bad about it as of now
Best Used for:
- home defense, target practice, hunting, and just having fun exercising your 2nd Amendment
Would recommend: Yes

Replaced a standard carbine spring, at first glance I didn’t think it would fit in a 6in buffer tube sb tac pdw on a 308 win. It does and it greatly helped reduce felt recoil. Difference was night and day and I will be ordering a second.
Pros:
- cost
- Fit and Function
- Less felt recoil
Would recommend: Yes

I ordered this due to cycling issues on my Aero M5 build. Turned out I needed to open up the gas port on the barrel. Generally 308 ARs are overgassed, not undergassed. This model seems too long for either carbine or rifle length tube. Again it works, but I ended up trimming a couple inches off to make it easier to put in my carbine length tube. My rifle cycles flawlessly.

I haven't built my 308 lower yet, but I put one of these in both my 5.56 & 300BLK. I wasn't really having any cycling issues with either of them, but these springs are a nice cheap upgrade. Going semi-budget with this build, but this part is no brainer. Well worth the few extra buck over mil spec. The spring does sound different, too.
