I have not received it?
Arca fits well to mpa chassi , knob locks it up tight !
Some might think picatinny is slight undersized but works fine
ARCA rail adapter is very high quality extremely happy with my purchase I will be back.
Great adapter! As should be expected the Arca adapter rocks! It works perfectly with my Fast Track Arca Rail on the RPR. Great product great company. Highly recommend them.
Hi quality everything on this adapter is well machined
