What ever happened with that Delrin lower project. I havn't heard anything about it for some time now...

One more time... Delrin, while having marvelous machining properties (I know first hand), is too soft for use as an AR lower, or upper, for that matter. I think the material used by Cav Arms for their lower is probably the best synthetic for this use.

2 more times! Not Delrin! Cav Arms uses a glass filled nylon, an excellent material at a reasonable price. I know of many other resins that are far superior to nylon but the cost and production hassles wouldn't justify the expense. Go [url=www.boedeker.com]here[/url] if you want to buy some and try yourself. Just make sure it will show up on an X-ray machine or whatever they use in airports these days. You will need some type of reinforced/filled resin.

Actually, DELRIN 570, which is 15-20% glass-filled, might make a good lower.

I thought someone on this forum was taking orders for delrin lowers a while back, that's why I asked. I cut a lot of plastics and you are right about the machining characteristics of delrin. But, the only are I see as a problem for an AR lower from the material is the thin sidewalls of the mag well, and these could be made a little thicker... Regards, Ray
