Description
Short cans usually mean loud cans. The Jaguar Fatty from BUKTEK breaks that rule. At just 4.5 inches long and 6.61 ounces, this little titanium can hangs with suppressors that are noticeably longer, and it does it without turning your AR into a gas-blasting mess. The secret is Jaguar's Intermittent Flow baffle system, which interrupts and redirects gas through a series of staggered, variable-depth chambers instead of letting it rush straight back at your face. The result is quiet performance, minimal blowback, and a rifle that cycles clean.
Why the Fatty 5.56 Earns Its Spot on Short Barrels
The Fatty gets its name from its 2-inch diameter, which is where the expanded internal pockets live. That extra volume is what lets a 4.5-inch suppressor punch above its weight on sound reduction. It's built from aerospace-grade Ti-64 titanium using additive manufacturing, so the internal geometry is far more complex than anything you'd get from traditional machining, and the whole thing is wrapped in a Flat Dark Earth Cerakote finish that looks right at home on an FDE build. On an SBR or pistol-length upper, the added length and weight are barely noticeable, which is exactly the point.
Smart Details on the CAF556TH-NF
Two features here deserve a callout. First, the standard HUB mounting cap means this can threads onto the huge ecosystem of HUB-compatible muzzle devices already on the market, so switching between hosts is quick and painless. Second, the replaceable aluminum end cap is a genuinely practical touch. If you ever catch a baffle strike on the end cap, you swap in a new one yourself instead of shipping the whole suppressor off for repair. Rated for .223 Rem and 5.56 NATO, it also works with smaller bores like 5.7 and rimfire calibers, making it a handy do-more can for the safe. BUKTEK backs its Jaguar line with a lifetime warranty against manufacturing defects, which says a lot about how much faith they have in the build.

Frequently Asked Questions
Will the Fatty 5.56 work with the muzzle devices I already have?
If they're HUB pattern, yes. The Fatty uses the industry-standard 1.375×24 HUB mounting system, so it accepts quick-detach mounts and direct-thread adapters from most major manufacturers. That makes moving it between rifles quick and keeps your mounting options wide open.
How quiet can a 4.5 inch suppressor really be?
Quieter than you'd expect. The Fatty makes up for its short length with a wider 2-inch body and Jaguar's Intermittent Flow baffle system, which uses staggered chambers to slow and cool gas more efficiently than a straight-through design. It holds its own against longer cans while keeping blowback to a minimum, which is a big deal on gas guns.
What happens if I get a baffle strike on the CAF556TH-NF?
If the strike hits the end cap, you're in luck. The Fatty ships with a replaceable aluminum end cap, so you can order a new cap and swap it yourself instead of sending the suppressor back for repair. It's a simple design choice that saves real downtime.
Can I shoot calibers other than 5.56 through the Jaguar Fatty?
Yes, anything with a bore smaller than .224 is fair game. That covers .223 Rem, 5.56 NATO, 5.7, .17 HMR, and .22 LR. Just keep in mind rimfire ammo runs dirty, so plan on cleaning more often if you feed it a steady diet of .22.
