Buffer Retainer Broke Through Buffer Tube

Recommended Posts

I hardly have ever bought a brand new gun.  After watching and looking at the DPSM G2 I decide to buy a Recon G2.  It arrived two weeks ago.  After a good cleaning and some lube I took it to the range today.  I thought I would dial in my EOTECH.  I did that pretty quick.  The recoil is nice and easy.  It is a lot smoother than the M1A I had been going to keep, but decided to sale.

Around about the 23-27 rounds I had a misfire.  The round had a very light primer strike and I found that odd.  I chambered another round and the same thing.  I pulled the takedown and the buffer retainer flew out.  I started looking at the buffer retainer and it is bent.  I found the spring in the trigger assembly.  As I looked closer you could see where the buffer retainer had broke through the buffer tube.  New rifle less than 30 rounds.  It was too late to get a hold of DPMS for warranty service so I will do that on Monday.  

By the way when you call the warranty service for DPMS the voice mail is for Bushmaster.  I did not know they were one in the same.  I knew that Remington had bought in to DPMS.

Anyone ever have the buffer retainer break through the buffer tube before?  By the way the ammo was was just PMC .308 factory loads.

You are ok. Lots of tubes have that cutout. Keeps the tube from spinning. Looks like they didn't tighten it enough during assembly. Do you have an armorers wrench? Back off the castle nut, hold the pin down, and turn the tube in one more rotation and you should be good to go.

 

Or...just send it back and let them fix it if you don't want to buy a new pin.

I built my first AR-15 when I was 19. I had no help and didn't know a thing about them. I left the tube out a little not wanting it to interfere with the pin. It should have made more sense, but I'm not a very "mechanical" guy. First shot bent that pin to hell and I had to hunt down a new one. While installing that one it all made sense and I could see where I went wrong. Easy fix. Let us know how it goes.

Hit Brownells this afternoon and my replacement parts under $5.00 should be on the way Monday. 
Thank you to everyone for their help.  Looking forward to getting this fixed and back to the range.  I pray this will be all the issues I will have with this rifle because I really want to like it.
