What airsoft housings are you using for these projects (?)…...and how are they holding up with blank-firing (?).
Could you share a little more inside/parts information/photos as these look interesting.
Last......are you using .45ACP full-length-Blanks, or the 9.3mm blanks made from cut-down 5.56mm brass...…..or the other optional 46mm-Blanks (?).

The M3a1 was my first build. The M3 came next with some improvements.
Both use original Bolts and guide rods/springs. The bolts are drilled for a firing pin and milled for AR hammer clearance and M3a1 finger cocking slot.
The barrel collars are machined to match the Metric thread pitch of the airsoft housing.
The mag well is larger than original so sheet steel is added inside the fit the mags.
The M3a1 uses thealuminum airsoft ejector housing while the M3 was cut and narrowed to fit an original. (The cocking lever moves but doesnt function)
I machined a custom trigger pack for the M3a1 but went with a drop in AR trigger pack for the M3 build. Both use original triggers linked to the AR trigger via a transfer bar

Im still working out aperture sizes for reliable cycling. I live in town and re-enactments are still a few months away. The housings are decent and should hold up to blank and live fire. The fire control group area may prove to be a weak point after serious ammo dumping over time. Well see. Ive looked at a Dunrite Armory bfong that uses these same airsoft guns and it was all but rattled apart with ovaled out trigger pins.
