I mean junk lower, not the composite it's self. The fitment was crap with my upper. Gaps and misalignment with the threading for the buffer tube. The white material and the lower are one in the same except for color. I'm not against composite for lowers, I have 3. These just plain suck and not worth the time.
Sorry you had a crap experience with your lower receiver. I did a fair amount of searching, and all the information I have found indicates the lower material to be much tougher than the filler. The difference is what made my consider using heat.
It wasn't to hard to mill out. I used an X Y vise with my drill press. If your a machinist you should have no problem finishing it relatively easy
I am not interested in another lower receiver, but as an engineer, I am very interested in innovative ways of doing things. Kudos to EP for coming up with their plug method. As polymer becomes the new aluminum, this plug method could be the next standard in 80% receivers. I am curious to different means of removal. After all, running a heat or Dremel requires the same amount of skill. Maybe even more with the heat gun.
As far as machining, other than my "toy" gun, my lowers are from raw billets I machined.
Lowers are junk. Plastic "jigless" piece of crap. Holes didn't match up for the bolt catch and their customer service is garbage. Move on and buy an aluminum one. At least you can tig weld if you make a mistake.
Anyone know if the white plastic "plug" could be removed by melting it in an oven, etc?
No. The whole thing is plastic and will melt as one. Has to be milled. There are tabs as well that mold the lower and the off colored plastic together. They are definitely one whole chunk of crap. The reference marks are positioned wrong so you have to use a jig anyways. The pre-milled rear takedown pin hole is a tad too high too.
As far as plastic being junk, not really. I like my lightweight "toy" gun and you can bet the next major change in military rifles will be made with great deal of plastic. Plastic requires far fewer resources and processing.Like it or not, it will happen.
Concerning the white plastic plug, it is not the same material as the actual lower and likely to have a different melting point, higher or lower than the lower receiver. Too, if it is lower, will the receiver material, likely some form of Kevlar composite, stand the temperature required to melt the white plug. Let's face it, removing the white plastic plug with a Dremel, etc is tedious, but doesn't require any more skill than to operate a heat gun.
I am a machinist as well as manufacturing engineer. I can run a Bridgeport mill and have full blueprints, etc, but haven't a lot of use for this lower, but have a great interest in innovative approaches to problem solving. Hmmm.... maybe a a matched set of lowers made from AmpCo..? :)
