Aero Precision now has two new AR-15 lower receiver offerings that are worth mentioning. They are offering “pistol” marked lowers. Pistol markings are not necessary (see this post about the legalities of AR-15 pistols) but some people do prefer them. They can be tough to find so Aero Precision has stepped up to fill the niche. I should also mention that Aero Precision lowers are particularly well suited to pistol builds since they thread the selector detent hole for use with a 4-40 set screw which gives you some additional receiver extension options.
Additionally, they are offering multi-packs of their regular lower receivers in quantities of 3 and 5 (5 being the maximum number that will transfer on the same 4473 form). You can save quite a bit of money by purchasing them together and they are even offering 3 packs of their blemished lowers which will save you even more.
Last but not least… These limited edition Ghost Gun lowers are now available for pre-order. I generally don’t care for anything other than plain lowers but this is hilarious.
