Hydraulic Buffer & Spring Package - For Pistol Caliber RDB
For CMMG Radial Delayed Blowback (RDB) Pistol Caliber Guns in 9mm, .40 S&W and .45 ACP
Package Includes RB5005 3.25" Buffer & Sprinco .223 Carbine Extra Power Buffer Spring (Red)
The CMMG Radial Delayed Blowback guns run great, but recoil impulse can still be noticeably reduced and shot recovery time decreased by using this buffer and spring combination. This brings these weapons to their full performance potential. Get the performance you desire and make your RDB amazing. Since the RDB action has a BCG that is the same length as a gas operated AR15 and longer than a blowback 9mm, it requires a buffer that is 3.25" in order to work in a standard carbine buffer tube and because the RDB doesn't require as much buffering as a standard blowback 9mm does. In order to use one of our 9mm buffers with an RDB gun, you would need to use an A5 buffer tube, but that is not necessary unless you have a 10mm.
* For 10mm models use an A5/AR10 carbine buffer tube with an RB5007 buffer and Sprinco Red Spring.
