Has anyone had any experience with KAK 308 double ejector bolt ? Thinking getting one for a PSA AR 10. Any thoughts would be appreciated. Trying to eliminate extractor burs and ejector swipe . I have the springo orange spring ,carbine heavy buffer, superlative adj. gas block and still having issues . Yes i am a poor. Thanks for any info. By the way the gun likes “LC” M118 SB
