The multistage system uses a second stage to reduce felt recoil. Gen 4 construction omits the earlier weight O-ring, secures the polymer end piece with a roll pin rather than a screw, and uses a machined rod cap and washer in place of the previous snap-ring arrangement.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe SRS-9 can be installed with or without a buffer retainer. For proper operation in a 9mm build, the removable weight at the rear of the 9mm bolt carrier must be removed.
