Take on aftermarket brass and aluminum Air Force breaches?
I purchased a brass one on eBay and returned it as the machining was not acceptable. There are a few individuals that offer Air Force aftermarket parts. One concern I heard was they need lubricated unlike the factory ones. I noticed Talon Air only offers brass hammers not the breaches. Looking for input from those with experience.

I have a brass breech on my .25 Talon-Dor. So far, I have had no problems but I guess time will tell! :5:
Nothing works as good as delrin. Aluminum will gall the barrel when cocking and heavier pre loads.
I still have a delrin breech on my .257 and I have shot it with 4200 psi fills. It is a good material and on a stock gun I don’t see it failing. It might wear out after years of use.
I have a cocking setup that let’s me run aluminum breeches on my .257 and .308. So far I only have one on the .308. It is more for the hhigher pressures from the larger calibers.
Brass and aluminum create metal dust over time when used as a bolt.
Delrin is self lubrication. Just keep it clean. In time it might need to be replaced as it wears, but they are cheap from Airforce.

Just lurking here as I have no real experience. Only a few hundred rounds through the .25 Condor SS.
