Armscor Rock Island Armory 1911 A2 Double Stack Magazine Basepad 54152



Armscor Rock Island Armory 1911 A2 Double Stack Magazine Basepad 54152. These fit the Mec-Gar Para P16 and P18 magazines or the Armscor factory 54180 magazines so they extend in the Armscor RIA 1911 A2 pistols with the extended magwell. 

This is a basepad to replace P16, P18, and 22tcm magazines with the metal base plate so they can be used in the RIA 1911 A2 with the extended magwell. The basepad replaces the metal base plate on the 1911 A2 Double stack magazines and work in RIA 1911 A2 with the extended magwell. 

Take care installing these. Damaged or mutilated returns aren't accepted. 

A customer of mine emailed me these instructions. A thin plastic shim or a thin feeler gauge. Either of those would be less likely to mar the base pad or magazine. 

Be sure not to use too much force or you can snap off the magazine the basepad’s tab.

  1. Needed the Mec-Gar P18 magazine, small flat head screwdriver, thin shim or feeler gauge and new Armscor extened baseplate.
  2. Remove the metal floorplate and magazine insert from the magazine. Start sliding the baseplate onto the magazine. Position the screwdriver to act as a fulcrum to bend down the rear of the magazine baseplate ear.
  3. Take the magazine to the edge of a worktable pushing down to continue the floorplate onto the base of the magazine while using a screwdriver as a fulcrum to bend the ear down. The base pad will slip right into place.
