I recently returned a rifle with a short throat to DPMS. I had never reported, nor experienced any feeding issues. However, DPMS did absoutely NOTHING regarding the short throat..in fact, they wouldn't even tell me what they did to investigate the issue. I was short stopped by customer service, and never allowed to speak with, or have questions passed onto the gunsmith who may have checked the short throat..
In any case, all DPMS did was say that they replaced my magazine as they had feeding issues, and they cleaned the rifle. I appreciate their cleaning it as I sent it in clean...I would rather that they left me with the magazine and dealt with the issue I had returned the rifle for..
Guess I will have to look into this and pay a gunsmith on my end to check it out. I am extremely disappointed in DPMS's failure to either: 1. tell me what they did to investigate the single thing I sent the rifle in for, and 2. Leaving me with the feeling that it will be up to me to deal with the short throat.
I always thought that when rounds stick in the chamber, and extracted rounds come out with the lands and grooves engraved on the bullet, that is a short throat...
I never did have feeding issues though, that is the reason this is in this thread. Apparently, DPMS feels that feeding issues are an easy fix...so send them your rifle..
