I'd love an MWS for it. but paying £800 for the a1 receiver, £120 for the stock and £300 for the m16 front end aaaand the £400 base gun a bit steep. If TM did an M16 gbb then i wouldnt hesitate to get it
As GiantKiwi suggested, use a WE as a base. I've built 4 L119's based on WE M4's and they are great. Performance is excellent, parts are cheap if required and easy to get and real steel stock tubes , stocks, grips etc fit.
