Rainier Arms is running a big blowout sale on the GWACS stripped lowers at below cost! These are great for super lightweight builds or those looking to build a complete lower on a budget. The CAV15 MKII lowers are a polymer construction that includes the stock and grip with a design that doesn’t suffer from strength issues like many other polymer setups do. My buddy Matt over at Jerking The Trigger has a sub 6 Pound Build that he’s working on and has had good things to say about the CAV15 MKII lower on it. Rainier Arms has a bunch of Black CAV15 MKII lowers and has decided to put them up for sale at below cost to clear up some inventory room and make room for new stuff. If you are looking for something like this, head on over to www.RainierArms.com and snag one now for just $89.95.
