I have a Sendra lower with a 20 inch upper installed. I was at the range today and found that the pivot pin was walking out after about 40 rounds. I think the pivot pin hole has worn to the point that it now moves under recoil. I have two questions, first is a Sendra a large hole or small hole lower?

I also would like to know if anyone knows a company that makes a pivot pin to fit that won't just push out? I want one that has a screw or something to help hold it in place.

Thanks for the info in advance..............

The only one who ever made large front pivot pin lowers is Colt. So, since your rifle is not a Colt, it is small or standard size.

Check the spring and detent that secures the front push pin, they could be worn or broken and that could be your problem. That can be fixed for about a buck.
