PRI Fat Boy Gas Tube for M4 Carbine / AR-15 Gas Tube
The PRI Fat Boy replacement gas tube for M4 Carbine is a replacement gas tube for M16/M4 rifles that uses a 9.8” long tube. One important benefit of using the Fat Boy gas tube is that it minimizes the weapon’s cycle time to 700/850 rounds per minute. It was made for use with the known buffer system and replaces the standard gas tube with no changes to the firearm. The Fat Boy gas replacement tube is perfect for barrels with length of 12” and 14”. Failing to hold open on the last shot is one of the common signs of over buffering a weapon.

Fit and finish are great, after shooting I can tell some difference but not alot. Still like the idea. I have a Magpul MOE guard and fits fine.!

Perfect for SBR

This gas tube smooths out the gas impulse and is perfect for 10.5" SBRs. I wouldn't suggest using this with barrel lengths over 12".

Works as Advertised

You installed this, along with an adjustable gas block, on a DPMS LR-308 with a 16-in barrel that was severely over gassed and had indications of incorrect timing on the extracted brass. An adjustable gas tube was used prior to this to eliminate the overgassed issues. A heavy buffer was also installed but did not fully correct the timing issue. The Fat Boy tube delayed the timing sufficiently. The function of the rifle is now great. As a bonus, the shot groups improved with the timing delay as well. If your rifle is running properly, you don't need this.
