That's a pretty one. It'd be hard to go wrong with it.
I'm sure someone that owns one will chime in. I know of no downside to a 20" tapered barrel. My LVT has a 20" VT barrel and I like it. It will have a bit longer sight radius for shooting factory or tech-sights.
Shoot it a while and decide what, if anything you want to improve. A little trigger work goes a long way. I like a softer bolt buffer. Many add a bolt release, which I dont do anymore. From there you can enjoy it or spend many hundreds of dollars on it according to what you are wanting to accomplish.
They are not hard to take down or clean. After a couple of times it will be easy. They are very much fun and addicting.
Go get it and good luck!
