  1. First match report

    Posted by Herb on Jun 12th 2017

    Springs approximately 1.5" longer than OEM. I guess this is because of the 10 round mag extensions shooters commonly add. Wire gage same diameter (.054") as OEM. Used in practice and PCC match this past weekend - about 200 rounds. Performed perfectly. Original OEM springs had failed to hold bolt open after a year.

  2. You need this!!!

    I bought three basepads (TTI) and they didn't come with the Power Spring (I purchased thru another vendor). The bolt wouldn't lock back. So a buddy told me I needed these, man. I'm glad I got them. Bolt locks back, good pressure when you load the magazines, and also no feeding issues. Thanks.
