Lancer announced that its new Adaptive Magwell is now shipping. The unit is a simple magazine funnel that can be added to virtually any mil-spec AR-style lower without tools or permanent modification to the gun. See this video on how to install the piece:
The unit is machined from 6061 T6 aluminum, and the MSRP is $99.99.
I believe that if there is enough interest in these units, Lancer will invest in a mold for making a polymer version of the Adaptive Magwell. As many readers know, having a mold made can be quite expensive. Sometimes a company will make a limited number of machined parts to test the market before deciding to invest in a mold. I have no insight into Lancer, but this could be the plan with this product.
