I have both as well. I prefer the DPMS over the Oly, mostly for resale value should I ever decide to sell. Oly retooled everything a few years back, and the Oly of today is about 100,000,000,000 percent better than they ever were back in the early through late 90s.
Still, you will find that they carry somewhat of that reputation to this day, especially here on ARFCOM due to their conduct. That's part of what motivated them to start their own forums.
You're probably gonna hear a lot of slamming or praise of Olys, and heres why:
There are still some nuckle dragging trolls around that will bash Oly every chance that they get. I can almost categorically guarntee you that they have not handled an Oly part made since 2000. I used to be one of them back in the day.
I was the night manager of a gun shop/range for 7 years in the 90s and I had to fix LOTS of them, and their mag wells were WAY out of spec (ok, inconsistent from lower to lower at best). I convinced the owner to stop carrying them after a full year audit of gun sales/repairs showed that we were doing repairs/replacements on Olys nearly 100% of the time. Oly NEVER re imbursed us. Oh, and we fixed them because Oly would cuss out the customers, accuse them of using out of spec ammo, all sorts of stuff, even refusing delivery of guns returned for waranty repair. Any profit margin that we had in an Oly (only about 12%) was eaten up in repairs fast for us.
That is not the case today. From what I understand, they bought new CNC machines and programs. Everything that I have seen since about 2001 has been in spec, great fit and finish, and well deserving of a good name and reputation. I would not hesitate to use a new manufacture Oly reciever.
