I have posted this before but we were not able to update the pictures on the original after the photobucket debacle so here it is again. Hopefully it will help BAR and FNAR owners suppress their rifles, they are alot of fun.
SHORT VERSION:
I wanted to suppress my Browning BAR ShortTrac in .308 Win but for over a year I couldn’t find a machine shop that would thread it due to not being able to remove the barrel from the receiver. Luckily I was referred to Class 3 Machining in the Dallas area for barrel threading as they are familiar with the FNAR that is dimensionally similar to the current BAR. Morgan of Class 3 Machining was able to remove 4.5” from the 22” barrel to get enough diameter to thread it 5/8X24 which is the standard .30 caliber thread size. The barrel is now 17.5” long (the goal was somewhere between 16.5” to 18”). I’ve read that removing barrel length from the BAR or using a suppressor will result in problems with the gas system for various reasons. I’m happy to report that the BAR, like the FNAR, has a fully adjustable piston gas system that is functioning perfectly with the shortened barrel and a SilencerCo Harvester suppressor. I’m running the gas system half open after test firing at multiple settings so there is room to adjust for more or less gas in the future if needed. The rifle is now my primary hunting companion, many hogs, deer, and coyote have been taken with it.
