buddy has one and is amazing! great value and great price. I'm looking to build a del ton but most of the kits are out of stock. try to get a chromelined 1 in 7" twist. it's a $45 upgrade that extends the barrels life by 4 times and lets you shoot higher grain military .223/5.56 accurately. they have some premise kits with 1 in 8" twist which would be choice number 2

I did a Del-Ton build, love it. Good info on them and others at AR15.com
