This great looking set from X-Fire/PDI would be a good add-on to your VSR-10. Hope that it fits the AGM version (MP001) of this rifle... "This set includes Remington M24 type Receiver and Mount Base(Rifle Scope Rail). R means Remington. The ejection port is cut deep, it is particular type of M24. Please note: The picture shows the VSR builds  with  the Remington KIT. It is a high grade set so there are Handle and Boss."
