Mo rails no problems
We decided there weren't quite enough rails on the stock MK 2.1 so we've concocted a dual rail to replace the orange muzzle and glue in side rails for those who need that extra bit of picatinny, additionally this kit includes an extended mag release (3mm/.125" longer) and a safety delete.
This kit does require the use of the original muzzle retention socket from the inside of the stock muzzle so be careful to not throw that piece away! By using the stock piece the lifespan of the muzzle receiver is much longer than if the part had been a printed replacement.
Please note that the additional rails are NOT compatible with the original holster that comes stock with the MK 2.1
Kit includes:
x1 Dual muzzle rail (ONLY PRINTED IN ORANGE FOR SAFETY)
x1 Left body rail
x1 Right body rail
x1 Safety delete
x1 Extended mag release
