David Tubb has released the new version of his famous precision bolt action rifle. The rifle is called “Dynamic Target Rifle”, but I bet the name Tubb Gun will stick to it, too. It’s been seventeen years since the introduction of the first Tubb Gun (TUBB 2000) back in 2000, and the new one has some interesting improvements and features.
The new rifle is a modular design. It allows changing calibers by replacing the barrel and bolt head and adjusting the magazine. Exactly, you are not changing the magazine, but tuning it to fit the desired cartridge. New magazines are machined ones, which makes them tuneable and more precise. The magazine capacity is 13 rounds for .308 Winchester and decreases with wider case body chamberings down to 6 rounds for .338 Norma.
Barrel changes don’t make any headspace issues, because barrels have barrel extensions much like what we see in the AR-10 design. The receiver itself is made of 70 series aluminum (I assume 7075) and has an integral top Picatinny rail. The action is claimed to be 175% stiffer than a comparable Remington action.
Another unique feature of the new Tubb Gun is what they call “Stable Bolt Technology”. This system allows to keep the bolt straight and aligned with the bore axis. That is achieved mainly due to the spring loaded centering bushing at the tail of the bolt. Locking lugs and sear geometry also aid the alignment of the bolt.
The Tubb Gun also has a Picatinny quad rail handguard with rounded rails. The rifle comes with a new Tubb bipod and has a folding stock. There are also a number of other features, which are common for such precision rifles: free floated barrel, adjustable stock etc.
