This service includes the conversion of any off the shelf AR15 barrel to work in a Lewis Machine and Tool MRP upper. This conversion only works with small frame (AR15) uppers. We do not do conversions for the large frame MWS (AR10) uppers.
You will need to supply:
- AR15 barrel (any length, any caliber)
- MRP upper
- Cross Bolts
This conversion does not include a gas block or gas tube. We recommend using an SLR low profile gas block and a normal, bent style gas tube with the conversion due to it's low profile and quality.
**Please note that this is a permanent conversion and once done, the barrel can only be used with the MRP Platform**
