The third new product video from RA-Tech is their new Steel Bolt Carrier made for the GHK M4 Gas Blowback Rifle. It is a heavier bolt carrier based on user feedback that the default bolt carrier in the GHK M4 GBB Rifle gets deformed at the corner due to wear and tear. Their aim is to resolve this problem with a heavy duty bolt carrier.
