Sprinco Yellow AR-15 / M4 Reduced Power Carbine Buffer Spring
Sprinco AR-15 buffer springs are made from high quality Chrome Silicon wire stock which is used in a variety of applications from Formula One to motor valve springs which can see up to 15,000,000 compression cycles in a single race. This makes it the perfect choice for a carbine which will see far less cycles than that over it’s lifetime. In order for this carbine buffer spring to retain its strength, Sprinco heat treats, shot peens, and treats each spring with a proprietary formula that retains spring efficiency for as long as you have your rifle. Sprinco buffer springs are a great option to improve the long-term reliability of your AR-15.
This reduced power carbine buffer spring is awesome for use with simunition and UTMs for Force-on-Force training. This spring is also great for competition builds with lightweight bolt carrier groups.

The spring worked perfectly and fixed my problem. What I am more impressed with is my first purchase from Rooftop Defense. Fast shipping and excellent service 10/10 thanks again!

Was having numerous issues with my AR 7.62×39 build. Undergassed was one of the problems, it was short stroking. I ordered this Springco reduced power buffer spring and it seems to have resolved the issue. Went through Rooftop Defense cause it was a little cheaper. Thank you Rooftop Defense!

First off, a class act company! I will purchase from them again. Second, this lower powered doing did the trick. My 7.5 300 blk out pistol was short stroking, a little under gassed. Now she runs like a champ. I’m very happy. Thank you guys!

Exactly what I wanted it slowed down the cycle and softened the recoil would buy another one for my next ar. It shipped right away very pleased with RTD.

First of all, love doing business with RTD, they were quick on processing and in no time I had my sprinco spring in hand and ready to use! My current situation at the time was a 300blk that was under gassed, read up on this reduced spring and gave it a shot, completely fixed my undergas issue and I have a clean cycle every time without issues! Thnx RTD!
