I learned to measure twice and order once...lol Bought the wrong rail!

[HMM]

Let me just say SLRrifleworks rocks!  I bought my 3rd rail from them for my 308 AR (other 2 were for AR15s).  Evidently I just eyeballed my upper and thought it was the higher of the two.  Stupid me...  And I didn't bother to check this before putting my upper together - I was like a kid opening presents on Christmas morning, I immediately put the rifle on the vise and began torquing the barrel nut down and putting the gas block on.  After all that I slid the rail on to mount it and what do you know, it's higher than the rail on the upper.  I immediately thought I just ate the cost of this rail for being stupid...  So I come in eat and calm down from kicking myself and think I'll just drop them a line to see if I could possibly pay a stupid tax and restocking fee so I could exchange it.  I had scratched the barrel nut a tad with the tool to tighten it so I knew it wasn't going to be an easy swap unless I could just trade out the rail itself.  

So it's 6:3ish-7:00 and I e-mail them with my order number and issue, offering to kick in some extra.  To my amazement I get a response within 5 minutes!  And they offered to swap everything out free of charge.  I have to get a new barrel nut too because it's a smaller size for the lower profile rail, which made me feel even worse because I was hoping all I had to do was change out the rail itself.  Even after again asking if I could throw in some extra they still said no.  Needless to say I'll order my next rail from them and ever other rail I ever use will be from SLRrifleworks.  That's top notch customer service right there!

Now I'm really confused too because I just measured my upper rail height and it's 0.196".  

From the picture I have it shows the low pro one is 0.150" and the high profile is 0.210"...

Maybe I missed it...what upper?

[HMM]

It's a PSA upper, got the upper and lower on a blemished sale.  And I took it off the lower and measured at the back center of the tang area and got 0.184.  Measurements were all over the place back there...

I got my rail in today, test fit looked good.  Sadly I had to run out so I couldn't torque the barrel nut down until just a few minutes ago, everything lined up great!  I'm super stoked!  Just have to torque my surefire muzzle brake on and it'll be ready to test fire!

Its all good when a plan comes together !          Wash

Glad you got that figured out - FYI, Odin Works has another way to measure 308 AR Upper Height:

(It would be nice if they wouldn't use the term "AR-10" to describe a "LR 308" type upper)

How's it doing now? I just ordered a 14" low-profile keymod SLR Solo (and their barrel nut wrench) for my 308 Oracle, after sending them an email asking for a code. Got one for $50 off!
