ironmonster Posted April 9, 2015 Report Share Posted April 9, 2015 So I took my new Aero precision rig to the range today, Fired 40 flawless rounds through it and was feeling pretty good. Got it home and opened her up to do a wipe down and WTF! The BCG was crashing into the buffer boss/tube. Id say at this point this buffer tube (which of course is a $150 PWS "enhanced" buffer tube) and the receiver are married for life. Taking them apart I think will do some damage to both. Anyway WHY?? As mentioned it is a Aero upper, Aero BGC PWS Enhanced AR-15 buffer tube (which measures 7" deep) I am using a Tubb's flat coil spring and a DPMS 2.5" buffer When I push the BCG into the buffer with the spring and buffer in place it goes all the way back to the sectional change in the carrier and hits I have a second rifle set up almost exactly the same (same spring, buffer, upper and BCG but using a UBR/rifle buffer tube and it shows marks where the carrier touched, but did not do the damage this one did.
