These base plates are CNC machined from billet aluminum and allow for positively seating Para/RIA style magazines in pistols that have mag well funnels.
These black base plates are 0.100″ taller than the traditional steel Para magazine plate and protrude slightly past a RIA mag well funnel. It does not increase capacity.
Dawson Precision makes these plates in three sizes – 0.100, 0.200 and 0.300. We have separate product listings for each.
This is for the base plate and purple interlocking tab shown. No pistols or other parts are included.
