Hey guys, I was wondering what your thoughts on the plastic spring guides or metal spring guides? What are the pros/cons of both besides weight differences?

Plastic or Acetal are easier to machine, may possibly deaden vibration, are lighter and what I have used in both my springers for thousand of shots with no obvious wear. Since springs lack the precision of finely machined metal parts its easier to fit a Acetal (plastic) guide for the best fit with just sand paper. I have made spring guides from acetal on my table saw with a bit of setup and finished them with a drill press.

It shouldn't make much of a difference if all else is equal. That being said, on a model of rifle that shall remain nameless, plastic rear guides were used for awhile but for some reason they would crack apart occasionally, so the manufacturer moved to steel. However, this type of guide did not go inside the spring at all, but sat below the spring- so any spring misalignment in the setup could have been the issue.

The idea of a spring guide is to keep, retain or straighten up the spring as its cocked.

Plastic wont do that, it flexes way too much.
Any tendency for spring to buckle, the delrin guide will be either flexed off its sat position under load or just purely flexing where the spring wants to go having no effect either way.

Diana 17 years ago went through a phase of them breaking along with others.
To make in delrin literally seconds, ok 2 mins job done. In steel with beefy 2" up spout lathe approx. 25 mins.
Delrins marketed purely as its easier and far quicker to make.
