Re: oly or cmmg
I own an Oly match upper, and a CMMG .300BLK barrel.
I dont know how great the build quality is of CMMG complete rifles, but the barrel I have from them is very nice. The coating does not scratch easily, and it shoots quite well. If the rest of what they make matches the barrel, I would buy a complete rifle from them.
I notice that Oly is a sore spot among several online posters. In total I own four stripped Oly lowers that were blems from about 20 years ago. I have one built up using and Oly lower parts kit and an Oly k16 upper. The company was good to me, and quickly answered my phone calls. I ordered about 6 years ago. The price for the complete upper came to about $500. I thought this was a fair price. It fit very tight in my upper, and I had to file a little bit from the rear lug to get the pin through. That isn't a bad thing though because this rifle is TIGHT.
I take it out shooting with my friends as they enjoy being able to shoot AR-15s, and so far in just under 600 rounds I have only had one malfunction. It was the first round that I had chambered through the upper and the bolt did not seat. I rode the charging handle closed. After hitting the forward assist, I have had no other problems with it. Accuracy is good in my opinion. My friends and I mostly shoot water bottles and prarie dog shoot and sees, but I dont have a problem hitting them out to 125yds with my eotech.
The times I have taken it to shoot groups it has done well in my opinion. I shoot 2-3" groups at 100 yards using the eotech on a low setting. I know its nothing like some of the others on this site, but i am happy with it.
Some of the internet hate for Oly comes from people saying that it wont hold up to extreme conditions like those seen in combat. My question is, do you plan to take this rifle into combat, or do you plan to plink with it out in the woods with your buddies, or throw a few mags downrange when you get the chance. If its just for fun, Oly or CMMG will treat you well. If you plan to take it to combat, please consider something in a belt fed or full auto variety.
I may be a little bias towards Oly, but that is because I have not had a problem with mine. I also own other higher end ARs including a Colt match HBAR. Yes the Colt does shoot better groups, but I would expect so for the money spent on it!
