Is the polymer80 G150 worth it?
Machining out a polymer 80% lower is so much faster and easier than an aluminum lower though. The Polymer80 G150 offers a very good value in a strong polymer lower and includes the only jig and bits you will probably need to finish off your lower. No other 80% lower available offers the lower the jig and the bit set for only $80.
What is the jig for the polymer80 G150 lower?
The Polymer80 G150 lower comes with it’s own jig and a pistol grip screw and square nut insert for the pistol grip screw to thread into. I appreciate that feature because other polymer lowers like the EP Armory can be very tough to get the pistol grip screw into.
What’s the difference between the G150 and G150 with the gap?
The measured difference in width between the original G150 (4.66mm) and the new one (4.34mm) was about 1/3 mm. That doesn’t seem like much but after you subtract out the thickness of the bolt catch (3.83mm) the gap difference is really 0.83mm vs 0.51mm. If you should have a gap that is too large the fix is pretty easy as outlined below.
