Product DescriptionThe KynSHOT RB5015HD Recoil Buffer is a heavy-damped hydraulic buffer system engineered for 9mm pistol caliber carbine (PCC) builds that use a Mil-Spec style carbine buffer tube (7" internal depth). Designed as a simple drop-in replacement, it can be paired with virtually any buffer spring and helps deliver smoother cycling and improved reliability. Optimized for PCC applications, the RB5015HD is ideal for barrel lengths of 8" and longer and is especially effective for suppressed PCCs, helping soften recoil and control bolt movement so the system stops just behind the bolt catch.Product Highlights Hydraulic, heavy-damped recoil buffer optimized for 9mm PCC platforms Drop-in replacement for Mil-Spec style carbine buffer tubes (7" internal depth) Helps reduce felt recoil (up to 30%) and smooth out cycling for faster follow-up shots Designed for suppressed PCCs and 8"+ barrel configurations; runs across a wide range of 9mm loads Compatible with other PCC calibers such as .40 S&W, .45 ACP, and 10mmSpecs Brand: KynSHOT Model / Part Number: RB5015HD UPC: 854476005171 Type: Hydraulic recoil buffer (heavy damped) Platform fit: 9mm PCC / AR-9 style builds using Mil-Spec carbine buffer tube Buffer tube requirement: Mil-Spec style carbine tube, 7" internal depth Recommended use: 8"+ barrels; suppressed or unsuppressed PCC builds Length (compressed): 3.9 in Weight: 6.0 oz Material: 17-4 PH stainless steel Operating temperature range (ambient): -30AdegF to +150AdegF Country of origin: United States of AmericaDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
