Product Description
Newly Made Item
Machined from 4140 CR Steel.
Hardness: 30 RC
Finish: none.
We designed these rails to align with existing holes (80mm Spacing - See Attached Print) and mount with M4 button head socket screws. If desired, these rails can be riveted in place by drilling through the threaded holes. The original rails are only 10 RC hardness and prone to 'roller denting' upon bolt-to-buffer impact. With enhanced material and hardness, these rails are much tougher than the original sheet metal design
Includes:
- 1 x Left Rail
- 1 x Right Rail
- 10 x M4 x .7 Mounting Screws
