Sprinco Red AR-15 / M4 Extra 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 extra power carbine buffer spring is great for heavily overgassed 5.56 guns and rifles chambered in calibers such as .458 SOCOM, 6.5 Grendel, .450 Bushmaster and many other heavier cartridges.

    Couldn’t find this part anywhere or at a decent price until here, shipping is reasonable and I really enjoyed the funny quips on the box, the ramen and US Constitution. My Dad saw it and he asked for it the moment he saw it. Everything was packaged well and all in working order. I will definitely shop here again. Aloha

    Great product and even better service. Made my day that they were kind enough to buy me a meal on top of my purchase. Earned my business moving forward.
