Description
Iron City Rifleworks is a leader in bolt carrier design and precision machining. These bolts are not lightweight just to save weight: they provide a fine balance between lower weight for better cycling while maintaining enough pass for years of reliable cycling. The C4V is a proprietary version of TiN which provides excellent wear resistance with a hardness of 2600 Vickers. One look at our C4V and you will know this is not your average TiN – it will last for thousands of rounds and barely requires lubricant . With a coefficient of friction 0.4 and only 2 microns thick, this BCG is a major improvement over its competitors. Matched with the Iron City Rifleworks Tacdriver Bolt, made of SAE 930 steel, you can be confident you have the very best.
Features:
- less felt recoil
- increased wear resistance
- faster cycle rate
- 2600 vickers will never scratch
- coefficient of friction 0.4, cycles even without lubricant
- forward assist
- 9.17 oz (259.9 g) including BCG, bolt, and firing pin
These competition Bolt Carrier Groups are designed for 556 & MUST be used with a reduced recoil system designed for lightweight carriers.
We HIGHLY recommend using an adjustable gas system and a reduced recoil buffer and spring for best results.
