Both me, and a buddy recently got Del-Ton lowers which you needed to add your own buffer tube. We both went with Carbine buffer tubes. But Both our retainers are barely held down by the tube it seems like...
If we try and get another turn out of the buffer tube it isn't in the right position.
When I installed the buffer tube on my Anderson Mfg lower I was able to get more of the tube holding the retainer. Like this...
He's worried that the retainer might pop out of place after some use with the rifle. I've put my leatherman tool on the retainer and I've tried to get it to slip past the buffer. Wasn't able to get it past the tube. Should we just run them? Or should we look at getting perhaps a different brand of buffer tube? He used a UTG branded mil-spec tube, and I used a Armalite mil-spec tube. He thought maybe trying a Del-Ton branded tube might be better. I said before you buy anything let me hop on AR15.com and ask a question.
If you could also post some pics of your buffer retainer, and let us know if you've had any issues with a retainer failing or buffer tube issue?
