Buffer springs don't get much attention until something starts running rough, and this is one of those small parts that quietly does a lot of work. The SOLGW Extra Power Rifle Buffer Spring is wound from 17-7 stainless steel and passivated for corrosion resistance, then tuned to deliver about 10% more tension than a standard mil-spec rifle spring. That added push helps keep the bolt carrier group moving at a more controlled pace, which translates to less battering on your internals over time.
This is a rifle length spring, so it's meant for A5/Intermediate and full rifle length buffer tubes, not standard carbine setups. Sons of Liberty designs their own rifles around extra power springs like this one, so if you're running a SOLGW build or any other rifle length system, this spring is a straightforward drop in match.
Suppressed rifles and guns that see a lot of rounds downrange tend to benefit the most from this kind of upgrade. The added resistance helps offset the extra gas and bolt speed that comes with running a can, keeping cycling consistent instead of letting things get bouncy or overly aggressive on the buffer tube.
The spring is color coded black so it's easy to tell apart from a standard mil-spec spring once it's sitting on your bench. Installation is as simple as swapping out your existing spring, no special tools or fitting required. It's the kind of low cost change that a lot of builders make early on simply because it works well and doesn't introduce any complications.
No, this is a rifle length spring meant for A5/Intermediate and full rifle length buffer tubes, not standard carbine length systems. Trying to fit it into a carbine tube won't work correctly since the length and coil count are different. Check your buffer tube type before ordering to make sure it matches up.
Yes, the extra tension in this spring is particularly useful on suppressed rifles since it helps offset the increased gas and bolt speed that comes with running a can. It keeps cycling more controlled instead of letting the system run overly fast. A lot of builders add this spring specifically for that reason.
The main differences are the material and the tension. This spring is made from 17-7 passivated stainless steel for better corrosion resistance, and it delivers roughly 10% more power than a typical mil-spec rifle spring. That extra push helps regulate bolt speed and cuts down on wear over time.
Not at all, it's a direct swap for your existing rifle length buffer spring using the tools you'd already have on hand for a basic buffer tube disassembly. No modifications or extra parts are needed. The black color coding also makes it easy to identify once it's installed.
