This $449.00 Kit comes with new trigger guard/bottom metal, both 5-round and 10-round TBM magazines, new action screws and instructions. For SPRs with box mags, this is a drop-in, no-gunsmithing upgrade that does not require gun modification or fitting to the rifle. (TSRs or PBRs with DBM equipment might require fitting by a gunsmith). Retrofit on SPRs can be accomplished in minutes with common tools (torque wrench required). Kits are available now through the FNH USA E-Store, Brownells, and Midway USA (item number 62655-01, MSRP $449).
