I received an email yesterday letting me know about a deal that is too good to pass up. Rainier Arms had a ton of their Forged Slab Side Upper Receivers made and actually have too many so they are blowing them out. The Slab Side upper is basically just like your normal forged upper but they have removed the forward assist option and added their logo on the side.
You might be thinking “Why no forward assist?” which is logical. I’ve always taught AR shooters that if your bolt did fully go into battery, you are better off to manually cycle the action by pulling back on the charging handle, eject that round and grab a new one instead of using your forward assist to cram something into the chamber that doesn’t want to go in there. Their are very few instances where you would actually “need” a forward assist. It also reduces weight while making the upper more low profile as well.
They are actually very nice uppers. I happen to be using one on my new 9mm AR Pistol I just built and its been awesome. Right now theses are on sale at $69.95 instead of the usual $125, only at www.RainierArms.com.
