Rainier Arms is known for only selling the best of the best products. You won’t find anything other than above average quality items there. When I saw that they were selling the new MILSPORT ARMS 80% 7075-T6 lower receivers I checked with the guys at Rainier Arms and they were really excited to have access to these very high quality lowers. Many people mistake the idea of an 80% lower as “a way to save money” when in reality it has nothing to do with that. It’s all about providing a way for law abiding citizens to exercise their right to build a non-serialized firearm. They are not sold in as high of quantity so they typically cost a bit more. However, Rainier Arms is offering these at an introductory price. Normal MSRP will be $90 but right now they get to offer the first run of them for just $49.95. Details and purchase link are below. I’ve also put a link to what I personally have seen to be the best machining jig on the market that will help you finish any lower in about an hour with just a hand drill and a router with amazing results.
These 80% AR-15 Lower receivers are forged in the US and are machined to mil-spec tolerances. Build your next custom rifle using a quality machined Milsport lower that are proven and tested.
— Radius are machined and blended
– 7075-T6 Aircraft Grade Aluminum
– Mil-Spec Precision Machining
– Flared Magwell
– Front magwell is textured for grip enhancement
– No FFL Required
– Made in the USA
The operations left to be completed are as follows:
— fire control well
– trigger pin hole
– hammer pin
– trigger hole
– safety selector hole
This is a not an FFL item. This is not a complete receiver and still requires machining to assemble a working firearm.
The MILSPORT ARMS 80% Lower Receiver can be purchased for a limited time at just $49.95. http://www.rainierarms.com/milsport-ar-15-80-lower-receiver-raw
