So I am almost done with the 6.8 SHTF rifle. Actually I've already ordered the last of the parts I needed on Jan 27th. I had the Lower already done and I ordered the DD 12 inch Lite rail and the PRI QC brake from Rainer Arms and they arrived 3 days later from Washington. Not only that but they called me up to tell me that i didn't need to order the DD barrel nut wrench because it's now included with the rail. I ordered my EoTech XPS from Amazon and also got it in 3 days. Now the sticky part. Also ordered on the 27th was the LMT enhanced 6.8 bolt assembly from Botach and i also ordered the DD 14.5 barrel and a gripod from Top Notch Tactical. All of these Items were listed as instock... I got an email from botach saying it was on back order and thought all was well as I figured it wouldn't take very long otherwise they wouldn't list it for sale. then I get an email stating that it is going to take 4-6 weeks to get the item in. For the barrel and grip I had to call TNT to get a notification that things were on back order but that he gets regular shipments and it won't take long, ever giving the benefit of the doubt I said well if it is going to take a while please get the things i was going to order next ready to go (310 rounds of SSA 6.8 and 2 mags) all of which he verbally said were in stock (Feb 2). No return email has been received as to the adding of these items to my order. Now my question, Is this Typical? am I overreacting in being upset about this? this is my first AR build and I have had excellent service up until these last few items (and they are pretty specific). Has any one else had experience with these companies good or bad? and finally, Am I getting ripped off?
