Ok, So LWRCI has something less expensive
I think the best bang for the buck is buying a 5.45×39 upper for your AR15, but you will have to do some research on using the magazines and possible changing a few things in your AR15 like a new buffer or a hammer spring. The main reason I didn’t start shooting one of these was because I didn’t have a spare lower to try out. Last year I did some shopping, but I’m not really a fan of swapping parts in and out of uppers and lowers just to do caliber changes. I think its a better idea to pick a caliber and keep a lower for the gun.
The 5.45×39 ammunition is dirt cheap and the Smith & Wesson seems to have been king of the realm for awhile, but direct impingement and 5.45×39 don’t mix very well. LWRC uppers have been increasingly expensive and yes, you can buy a whole new Colt AR15 for the price of an LWRC upper, but recently we were informed that the LWRC M6SL which is the lightweight stretch upper costs just about $1000. I got my LWRC M6A2 for more than than about 4yrs ago. Even though we’re selling them we want to hear from people on how they are holding up.
