Eugene StenAR v1.2

about

V1.2 update - small modification to MP5 handguard to prevent handle from flopping. Three new handle options added (thanks to nVi2x for modeling these)

V1.1 update - New Magpul style MP5 printable handguard with integrated side charger. Lower receivers now have fosscad symbol on the side.

If you downloaded the original release, you will have to redownload for these new features


A printed AR9 lower receiver that allows you to pretend you have an MP5

There are several "features" to this package that can all be used independently.

Credit goes to the original file I remixed from, which is AR We Cool Yet by ARTH, which is remixed from the original Ubolt by Ivan
Mag is DB's Sten mag
Side charger is modeled off of unseenkiller's general direction sights

Changes from the original version

Mag catch moved to the right side instead of left, for standard AR15 manual of arms
DB Sten mag modified to work with reoriented mag catch and to fit into lower
front takedown pin now has removable and replaceable plates
shockwave brace shortened
magpul style speedplates for mag
printable split pin for takedown pins
*Slappable side charger

IMPORTANT: make sure the BCG you buy is COLT compatible. The glock only ones will not work with the ejector. New Frontier Armory is confirmed g2g

Also, regular sten mags are NOT compatible with this lower. Only the mag in this file will work with this lower.
