FaRKle!

For the money they charge it better not be! The tech guy said he was going to rebuild my scope himself.

Yup, POF with their stupid high rail.

I fully intend on doing that too. We needed a better camera and I'm hoping that there's a Memorial Day sale on it. I'm going to have well over $1000 invested in this project (camera, ammo, muzzle devices).

Unfortunately I bring you a terrible experience with a well-known, and supposedly "high tier" company. US Optics didn't just send me one bad scope, but two, and made me wait over five weeks for it too! When I first bought this SR-8s back in February I noticed that the picture seemed unnatural. At the 1x setting the picture didn't feel like 1x. When I used both eyes open it felt like the image inside the scope was actually less than 1x. When looking through the scope and pivoting the distortion in the lens was very distracting and I couldn't track anything. I also noticed a high degree of curvature in the image at full magnification. Below is a photo of the scope at 1x. Notice how the lines in the scope don't meet the lines of the roof on the house 50yds away. Here's another photo of a garage 100yds away. I've again put straight lines along straight-edged features of the house to highlight the curvature in the image at 8x. So I decided to contact US Optics. Below is a timeline of my experience with them: -3/13: Contact USO with scope issues (including pics and diagrams). -3/18: Receive RMA label for scope to ship it in. -3/21: USO receives my scope. -4/4: After two weeks of silence I politely ask if they have any information on my RMA as I'm curious what the root cause for my issues were. USO's CS agent replies she'll put me in contact with somebody. -4/15: After not hearing back from anybody at USO in a week's time I called them this morning and spoke with the same CS agent I emailed previously. She said she'd have another person call or email me today about my RMA. It's now past their office hours and nobody's called or emailed. -4/16: I FINALLY get a hold of the person working on my scope.Surprisingly, he says that he tried to call me on Monday, 4/14. I confirmed my phone number with him, then looked through my phone logs and didn't see any calls from him. If he had called, why wouldn't he have left a message? Regarding my scope, he says that he doesn't see the less than 1x issue, and doesn't see the curvature of the lines issue outdoors, but sees it indoors. He mentions that he'll rebuild the scope for me. This tells me they haven't really worked on my scope at all at this point. Says it'll be at least another week before I get it back. -4/28: I received an automated "Order Confirmation" email from US Optics with a FedEx tracking number. The tracking number doesn't work (and never will work)... -5/1: I receive my repaired scope back with new serial number (since it's a new build). UPS delivers it (so much for the FedEx tracking number!). Today I looked through the scope at houses outside and inside my house and was pleased to see that the 1x image inside the scope matched well enough to that outside the scope. While pivoting around I noticed some distracting movement in the lens which made me worry about the curvature so I decided to check on it. Unfortunately, it doesn't look like that issue was fixed... Using the same garage at 100yds I took pictures of the SR-8s as well as a SUPER cheap Leupold Mk4 knock-off I got as a present 3.5yrs ago (airsoft grade). To my dismay not only did the SR-8s STILL have the distorted image, but the Mk4 DIDN'T!!! Needless to say, I'm very disappointed in both the product and level of service I received from a company with a good reputation for quality. I fully regret buying this scope and can't recommend the company. Looks like I may have to settle for some other company's 1-6x. Pics from today: SR-8s Knock-off Mk4

I'm prtty sure "Lewis Machine & Tool" doesn't make Armalite guns. It's an LM8 MWS variant. SR-25 pattern.

So now you can have a QD rail instead of QD mounts to attach to your rail! =P Is the weight listed with or without the barrel nut? I wonder how zero repeatability is with the front sight...

I have a case of it and haven't had any issues thus far.

Wolf Gold 1000rnds $350 shipped

Got my barrel back from Nefarious Arms today! So dimpling shaves about 2oz off of the MWS barrel. Yes, it's noticeable.

Uppers IME generally take a month to ship. Accessories about 2 weeks.

AR-10, SR-25, MWS, and OBR rifles use tapered firing pins. I'm not 100% sure on the compatibility though.

No issues on CBC/Magtech (Brazil), PRVI (Serbian), or Federal M80 ball with my Geissele triggers.

Same kind of people who design a barrel nut with 1-1/16" wrench flats that are extra narrow (Noveske)...

DSG Arms has the MBUS Pro set for only $125! You need to login to see the sale price. I ordered my set!

Lucky for you I have two MWS barrels to test this with :)

Wait, so are you saying the PredatOBR has a 20MOA rail or doesn't? (because it doesn't have a 20MOA rail). LaRue says 0-0.5MOA. I'll test my MWS once US Optics decides to get off their ass and fix my scope (they have terrible communication).

Well I was about to recommend a Mark 6 3-18x44mm... =P

See here.

Didn't want to wait for the S5 that comes out tomorrow?

They have a sale going on right now. Check their facebook for details.

It might be a bit of a stretch to draw any conclusions on length and thickness and which offers a larger contribution to accuracy considering one of your barrels is 416R stainless steel and the other is chrome-lined 4140 steel.

What are you looking for?

That's pretty common. A tapered firing pin can help with this if it's really bothering you though.

Is it cratering due to actual pressure issues or cratering due to excessive firing pin channel diameter?

You sound like my buddy. Every time he has alcohol he breaks out in handcuffs. That was an entertaining read, but doesn't really mean anything about steel cased ammo, but rather bi-metal bullets. It also only applies to rapid fire use cases. All that heat in the barrel exacerbates the detrimental effect of the cheap bi-metal bullets over normal copper jacketed rounds.
