FN MK16 SlapWell (Bump Lower)

Rifle Slapwell

A flared magwell at a fair price, the SlapWell provides a smooth widened  opening for faster and more consistent reloads for your rifle. The SlapWell instead of a magwell since  these do not use any hardware. No additional failure points, no tools, no fuss. Just get the lips of your receiver started and then slap into place. 

There are two versions of the MK16 lower, this item is ONLY capable of fitting on the newer receiver which has a noticeable bump at the front of the receiver. Please contact us before ordering if you are unsure which receiver you have.

Please note that some products  may have small imperfections or visible seams since 3D printing is not perfect and seams are a natural occurrence as the nozzle changes direction between layers. Products may also very slightly from product photos as I improve on the designs and release newer and better iterations.
