Nearly finished, we gbbr m4 base, upgraded nozzle, recoil spring, barrel and bucking. Exterrnaly clone geiselle mk4 rail, mlok for grip, pts pistol grip and trigger guard, slim pdw stock, t1 on high rise, rmr on 45 degree angle and m620v torch. Still got to change the muzzle.
Recently got my hands on the northeast sten. First RIF I bought 7 years ago was an AGM Sten aeg.
This is a major improvement.
I'll put a review up in the relevant section.
