Hello All,
I'll start off by saying I love my new rifle and wish that it was not having all these problems.
On January 22, 2012 I bought a new Olympic arms UMAR 22-250, After waiting a month for my new scope to arrive I took the rifle to the rifle range for the first time this last weekend. I am extremely impressed with the accuracy of the rifle. It was shooting sub MOA at 100 yards using Hornady 50 grain V-max. That's Good to Go.
Unfortunately I am disappointed with my new UMAR 22-250. I was braking in barrel using the Fire, Clean, Treat, Lubricate and Fire Method at the range and noticed a few problems,
(1) I noticed that the bolt carrier is damaging the buffer, when the weapon is fired and bolt carrier comes recoiling back instead of going with the buffer, it initially slams into the buffer and then completes its firing cycle. In a properly operating AR/M16 variant the bolt carrier rides the buffer it does not slam the face of the buffer and cause damage.
I was told over the phone that this is normal for the UMAR, Are any of you having this problem?
(2) The bolt is damaging the aluminum magazine follower (This has already caused the bolt catch to malfunction due to aluminum shavings getting caught in the bolt catch plunger).
I was told over the phone this is due to sending the bolt home on an empty magazine.
So if you own one don't do it. BTW this is not mentioned in the UMAR owner's manual that I received with the rifle.
(3) There is damage to the bolt key. I was told over the phone that's just the way they are receiving them from their suppliers.
Does your bolt key look similar?
4) I am not happy with the amount of play between the upper and lower receiver and my upper does not sit nice and tight into the lower, there is a obvious gap at the rear and the bolt carrier is not sitting exactly flush with the rear of the upper. Olympic arms rifles are known for there tight fit. This rifle does not have it.
(5) When the rifle is fired and the spent cartridge is ejected, sometimes the spent cartridge only gets thrown about 1 foot away.
What do you think could cause this problem?
Thank you all for taking the time to read my post, I truly appreciate your opinion and comments.
