From the manufacturer
Evolution Gun Works Sear Pin Stainless. We hold to the same standard of quality as all of our parts do. We have found that using a knife edge as part of our trigger parts reduces overall trigger pull weight. The smoothness of the material and the rounded corners give a great trigger pull as well. If you are looking for a replacement for a government issue AR-15 trigger you won't be disappointed with this part. Fits all Glock and Sig models. This is a replacement for the standard GI trigger pin that is used on current GI model AR-15 rifles. Package Contents: Evolution Gun Works Sear Pin Evolution Gun Works 10031-6: Sear Pin Stainless
