Pricey but worth it. A high-end firearm with all the features expected at this price point. Accurate, reliable, easy to use. The brace is not as stable as a proper stock, but very good compared to other braces on similar firearms. It also folds easily into a very compact form factor, perfect for backpack carry or to stow under the seat of one's vehicle. This is one of only a few .300 BLK firearms with the correct 1-in-5 twist for shooting subsonic ammo. With supersonic ammo, I get under 2 MOA at 100 yards (5 shot group). Subsonics produce groups of 2 MOA @ 50 yards (I have not yet tried subs at longer distances). Adjustable gas system works as advertised and is easy to adjust with one's fingers. The Rattler LT is not designed to reliably cycle subs un-surpressed, but Discreet Ballistics subsonic target ammo does cycle without a can. The price at Bud's is $2500 + tax and fees, and is the best price I've been able to find. All in all, a great little gun for those who won't compromise on a PDW.
