Equivalent buffer weights are \u003cstrong\u003e3.3 oz\u003c\/strong\u003e for C, \u003cstrong\u003e3.8 oz\u003c\/strong\u003e for H, and \u003cstrong\u003e4.7 oz\u003c\/strong\u003e for H2.

For proper fit, the bolt carrier must have a rear opening greater than \u003cstrong\u003e0.60 in\u003c\/strong\u003e; carriers with openings below that dimension are not compatible. During installation, orient the polymer bumper toward the rear of the firearm and the weight mass toward the bolt carrier.
