I am really partial to Plated Bolt and Carrier Groups.
Last year I bought a TiN plated BCG from Del-Ton, and just this week I got one from a Chrome Plated BCG at Midway (made by DPMS).
In general, the Del-ton finish is a bit less polished (like the DPMS as a bit of buffing on the finish, while the Del-ton was a bit more matte (prior to use). The difference is really minimal. +.5 DPMS
The machine work on the Del-ton seems to be more fine and precise. That is, the number of cutting passes on their CNC/Cutter seems to be more, so that the 'waves' between cut lines are less noticeable. It looks like the DPMS was made much more quickly with less total passes. I can clearly see (downright sloppily machining) where a second cutting process was added over a previous process (step in height/depth), and there is evidence the CG came loose a bit during the process (swirl gouges) . +1.5 Del-ton
The random slop of machine marks from machine process are not noticeable on my Del-Ton bolt, and she is very clean. If i inspect the DPMS bolt the same way, I see many dents, gouges, and scrapes from a sloppy machine shop production. +.5 Del-ton
Both are staked fairly deep into the case, onto the screws, but I do not see much (if any) deformation of the screws. I am sure their will not be any isse, but there you have it.
If I ever need another BCG, I will watch for another Del-Ton sale.
Note, I do not know who makes the Del-ton BCG (if they buy, or resale, or subcontract, or do it themselves)?
