Don't lump Polymer in with other plastics.  That stuff is tough!  And for wear surfaces like trigger and hammer pins, it might even outlast cast or billet aluminum.   :dunno:
If it was easy, everybody would be doing it.

If you are satisfied with a glock, no reason why you would not be satisfied with a poly ar lower.  If you don't like the look and feel of a glock then I'd steer clear 

I have built a couple and no complaints.  Sometimes I have had to do a little sanding in the tight spots but nothing major.

working on a 300 blackout with one.  Trying to get the whole thing under 5 lbs.  I am at 3.25 lbls right now, just waiting for the bcg and carbon fiber barrel.  Put a leupold delta point on it.  Man those things are lightweight!  I love it!


I've never heard of a carbon fiber barrel. Can you provide a link?

Thanks,


sam

Rob, would love to see you post up some pics of your build!

Some years back, one of the big shotgun manufacturers, Remington or Winchester I can't recall which one, made a shotgun with lined fiberglass barrels.  (I don't think carbon fiber existed back then.)  They were good guns, and really light, but they never went over very good, so they only made them 2 or 3 years.  The new Ruger LCR revolvers have a lined polymer barrel, and they seem to work good.  :twocents:
