| Hi guys my ffl dealer can get me a dpms lower brand new for a good price. It will have a A2 stock. What is the quality of their lowers? |
| A few weeks ago I was at a local gun shop that sells AR parts, I had gone there to check out the Stag lowers I heard they had. I looked at the Stag and then noticed there was also A DPMS lower in the case. I asked to see it also and I was extremely impressed with how well the lower looked. The finish was absolutely perfect and far better than any lower I have ever seen or owned. |
Yep. |
The DPMS lowers with the "F" prefix are now forged. |
OMG, not to spec...  Well if the teflon does nothing to help function then I guess they just function 100% because they are made well. They are hard coat anadozied (spec) then teflon coated IIRC. The machining marks I was referring to were just like the past Bushy thread that showed all the material left on the front of the magwell etc. They are not something that a coating, any coating, would cover up. |
The teflon coating does nothing for the funtioning of the durablity of the finish on the lower. It is there to look pretty. One may have thought teflon was a durable finish. It is, but it is not as tough as Type III anodizing. Any impact that will scratch, ding, or damage the anodzing will go right through the teflon as it is less hard than the anodizing. Anodizing is really aluminum oxide, the stuff sandpaper is made from. |
Understood, but if the teflon coating goes over the hard coat anodizing, how is this a bad thing?? Seems like even extra protection... |
A milspec receiver will be Type III, hardcoat anodized, nothing else. It does not call for any coating over that. DPMS receivers are "in spec" as far as physical dimensions go, but the teflon coating is "above and beyond" what the spec calls for. |
He means that the teflon coating is not to spec. However, as the DPMS lowers are hard coat anodized (per mil spec) then teflon coated, I still don't get the problem.... |
| I have eleven DPMS ARs in various configurations, and am very satisfied. Any functioning problems have been traced to operator error or ammunition. hy.gifhippie.gif[h.gifhug.gif |
Interesting. Curious how the teflon coming off would pull the anodizing underneath off, or cause a worse chip in the actual aluminum? Any experience with DPMS uppers showing the same results on the brass deflector? Seems they would be much more prone to chip there as well then? I have had DPMS, Bushy, CMT uppers all chip there, but none noticably worse than others. |
It could very well be that I had a bad batch of either anodizing and/or the teflon coating over the top. All I know is that I never saw a finish like there is on the MEGA receiver, all sparkley-like and I never saw such a large chip come off on a one time strike. The Bushmaster didn't chip at all. The metal and anodizing just dented. That MEGA receiver is now Norrell's tan. |
I wonder if Mega actually does the anodizing first like DPMS, or if they just skip straight to the teflon? |
I'd bet they anodize. They say they do. |
