We’ve taken feedback on thousands of M4 HPA adapters sold throughout 2022, to build what

we believe to be the perfect HPA adapter. A CNC feed tube and recessed CNC mag release

provide lifelong longevity, a flared magwell enables speedy mag changes, and an adjustable

shim gives excellent magazine compatibility and fitment (though you won’t need it for most


Our team worked their magic in creating a beautiful aesthetic that suits the pistol, while still

allowing the use of flared mag-wells and keeping bulk to a minimum.

It doesn’t end there, we offer excellent product support, lifetime warranty, and include spare

parts should you or your team ever need them!

Home Installation is Trivially Easy.
