Got this in Windham Weaponry's monthly newsletter. Thought it might be helpful. Met Erik last winter during factory tour. Real nice guy.

Smoothing up the trigger pull on a standard AR15

Most mil-spec AR trigger pulls aren't really the best they can be right out of the box. With a ceramic stone and a few minutes of time you can greatly improve the trigger pull of your AR15.​

​

Following the instructions below, you should be able to make the trigger pull both smoother and a little lighter. If you are using ammo with hard military type primers you may want to skip the hammer spring bend I mention here. For commercially manufactured ammunition the spring bend shouldn't affect reliability though. I only recommend the use of a ceramic stone as you can't really over polish the sear engagement areas with this type of stone if you work slowly and carefully. Do not use any other type of stone or sandpaper.​

​

As stated in the caption below, keep the sear engagement areas flat on the stone and as straight as possible. With a few passes you should be able to remove any minute burrs on the surface.​

​

​

​

When you reassemble the hammer and trigger make sure the hammer legs are resting on top of the trigger pin and not underneath it. A little Moly Slide paste on the sear surfaces will make the trigger pull even slicker. Once it's back together, perform a function test to make sure the safety and all the other parts are working properly.​

Thanks for posting this.

I'm wondering if this the method of cleaning up/polishing that people are suggesting be done to budget LPKs like the ones from PSA.

Erik's great. I have a Windham and I had some questions about some changes I wanted to make and he was very responsive both directly via email and on the Windham forum on ARfcom. Good guy.

I had purchased a Diamondhead rail from WW. While taking an armorers course at the factory, I asked him about it wiggling. He told me there was a design change and the new ones were more solid. He told me to email him and he would ship out a replacement with a return label, and to send him back the old ones once I swapped out. Real nice guy.
