R4.10 with 10 round magazine, it is here!

Since everyone so excited about their new R3, therfore I downgrade my S410 rifle to R4.10 bullpup with 10 round clip.

50lbs fish line trigger linkage
home made trigger & guard

and thank to Dimi3 for his clever way of making the scope mount. Total parts cost under $75, total time <30hrs for real. No special tools needed, only router, rotozip and drill press. Not perfect but it’s a bullpup and only 32.0″ flat.

Next ime I’ll go with etrigger, this fishline is not working as smooth as I would like.

enjoy!!!
