Ft Collins, CO --(Ammoland.com)- Plastics and serious rifles, from a friend and manufacturer:

“Use of polymers in firearms has become commonplace.

With serious rifles, plastic lower receivers may be arguable, but using plastic structural components to support the barrel is extremely unwise, yet both H&K and Beretta have done this.

Plastic is suitable for parts of a rifle that must be gripped by the hand or to which the cheek is pressed, because it does not heat-up as fast as steel or aluminum. However, plastic structural components will never be as durable as metal ones, and their use in inappropriate places will lead to rifles with short lives!

Metal rifles are heavier than plastic ones. No doubt! The judicious use of plastics/polymers can contribute to making the rifle less ponderous. Not in dispute.

Yet, in my opinion, critical, structural parts of serious rifles still need to be made of ordinance steel or aluminum. As such, the rifle will last a lifetime (pun intended).”

Comment: We all need to keep an open mind with regard to new manufacturing methods and materials. But, when our lives depend upon them, we need to stick with weapons and weapons technology with an established and respectable track-record.

New ideas and methods need to be constantly tested and retested. Some will prove worthy and be ultimately embraced. Most will not and will wither away.

It’s called “progress.”

    1. Here here. I never understood the allure of weaker materials for large structural AR parts?

      Now, carbon fiber? It’s got a track record we can measurably depend on, but it’s expensive.

      As far as polymer parts, a manufacture needs to show us some good old fashioned torture tests:)

      For the foreseeable future, I’m stickin with steel or aluminum.
