Anyone tried putting a suppressor on a BAR

[Hornedfrogbbq]

Gents, I love my BAR in .300 win mag. It was the first rifle I bought myself back in 1989. I have several other rifles in that caliber now (and larger) and am thinking about cutting the barrel on this one and putting a can on it. It is way light in weight in the fore end and barrel and has sent two buddies to the hospital for stitches. Since i have other rifles in this caliber, just tinkering with putting a can on the end to tame it a bit. BUT, obviously, it's a gas powered semi-auto. I assume the can will send pressures back and I might need a heavier spring.

Thoughts from the intelligentsia?

The image below is from the Browning BAR owners manual. I guess the decision to proceed would be based on how adventurous you're feeling or your desire to win a Darwin Award.

The fact that none of the various models come threaded from the factory made me intuitively think this was not recommended. If it was readily doable, I would think the 308 DBM would have been a prime candidate to have this feature as a hog rifle:

If i had to guess that since a suppressor immensly increases the backpressure. That whatever the bars recoil mechanism is. Probably was not designed to handle that extra force. That would be my assumption on why that disclaimer is there.

That was kind of my thought as well but wanted to toss it out there to see if anyone had experimented at all.

I would say that is a pretty stark warning from browning. I don’t think I have ever seen a gas operated semi auto threaded for or wearing a suppressor. But then I don’t hunt with semi autos.

Ahhh what the hell...just go for it....

Gas operated semi auto's are equipped with suppressor's all the time, BUTT the gas port size, bolt weight, recoil spring weight, etc , all have to be changed.

On AR type systems, an adjustable gas system is the first step, followed by springs and bolt weight changes. To do all this to a Browning BAR will be a tough row to hoe, as everything will have to be scratch built and individually tested.

I've owned several, including one in 270 WBY Mag that I should have kept. If the recoil is that bad, your best bet might be installing a BOSS system. Guys here won't like the idea, but all least it won't destroy the value of the rifle as they were a factory option.

Yep..

I had a hell of a time getting my two AR10’s to run reliably suppressed… I first swapped out the gas blocks for adjustable models and tried tuning the gas… then swapped out both the buffers and the buffer springs.. and after adjusting the buffer weight and gas about a dozen times on each gun and burning through probably a hundred rounds on each gun I finally got them running right…

Getting my suppressed 556 AR15 to run reliably wasn’t 1/10th the challenge… but it’s a piston gun, not a direct impingement gun.. that made all the difference in the world…

That's exactly why I think the OP's BAR would be such a challenge.

AR-15 and AR-10/SR-25 parts are common and relatively cheap, and even then it's still not easy to make a rifle work the first time. Adding a suppressor is a common thing on AR rifles, and the changes needed are well understood in the suppressor community, but almost every time some tinkering is needed

On the BAR a very talented and expensive machinist would have to make any parts from scratch. Making a gas block with a different port size wouldn't be beyond most, but any part in the bolt group to adjust weight would take some serious thought. Buying a spare bolt group and adding tungsten weights is the usual route. Even with those out of the way, custom made springs in various weights would have to be made and tested.

Sometimes simple is the best. Add weight in the forearm and butt, and add the dreaded BOSS muzzle brake.

Well in. Europe, Browning is selling suppressors for Bar:

BAR 4X TRACKS

browning.eu

and go to accessories.

I am planing to put a suppressor on my MkIII in 9.3x62

Like every black gun out there?

The verbiage in the European owner’s manual is different. Maybe the USA version was written y a liability lawyer instead of an engineer?

Was t referring to AR’s.
