View Full Version : Browning BAR assembly/disassembly

July 10, 2007, 03:20 PM
My Grandpa just gave me a Browning BAR 30-06 for my graduation. I started looking at it and I have no idea how to even start taking it apart. All I know is its about 20 years old, he won it at a deer hunters banquette and has only used it twice. So its in real good condition and I want to keep it that way.

Any help would be appreciated.

Assuming you know how to disassemble a firearm or have someone you know helping you, to disassemble for cleaning-
* Remove the screw that holds the trigger guard on and pull the trigger guard off. It will stay as a unit.
* Remove the screw that holds the forearm on. If someone has mounted sling swivels, it may look like a sling swivel, but unscrewing it will let you take the forearm off.
* Carefully remove the action spring by compressing it slightly and lifting the end clear of the retainer.
* Remove the action bars by lifting them off of the carrier and sliding them out.
* Remove the bolt handle by depressing the retainer and sliding the handle out of the notch. At this point, the bolt should lift out of the action.
* Clean thoroughly. Remember to use a cleaning rod with a bore guide when cleaning the barrel. You must clean from the muzzle. Scrub the action out as needed. Scrub the trigger group, but do not disassemble it.
* To reassemble, reverse the disassembly process. There are no "tricks" to it.
If you think you may have problems with the assembly, take pictures as you go.

What if there arent any screws for the trigger gaurd. This is where I'm running into a problem. No screws or pins that I can see except For where the sling goes and on the back of the stock.

You can get the owner's manual at
It describes how to get into the gas system pretty much as Scorch says from his second line, there being no trigger guard pins or screws.

As I recall - I once lived next door to the town repair gunsmith and watched him at work some - the BAR has no exposed pins or screws and the action comes apart by taking off the buttplate, then unscrewing the big stock bolt to get the buttstock off. Everything then comes out the back of the receiver.

Getting that slick side look required some gimmicks, I recall it as a rather complicated gun that he did not like to work on. I would not take it any further apart than the above manual shows without instructions. There are
disassembly books available from the NRA and Krause, maybe one of them shows the BAR.

In the meanwhile, clean the bore carefully from the muzzle, or with a Boresnake, clean up the gas system as in the manual, and it will serve for a long time.

This sporting gun is gas operated with a rotating bolt head that engages the shoulders of the barrel...sorta like the M16. And like the M16, the BAR's bolt head is attached to a carrier. Unlike the M16 (which is gas impingement operated as opposed to the gas operation of the BAR), the BAR's carrier rides on two parallel action bars which are attached to an intertia piece found underneath the barrel.

Upon firing, gases enter the gas port, filling the gas cylinder. Pressure drives the gas piston against the intertia piece which begins travelling rearward. This compresses the action spring and causes the action bars to travel rearward along the action bar (for want of a better term) path in the receiver. Because the bolt carrier is attached to the action bars, the bolt carrier also travels rearward and in doing so, cams the bolt, unlocking the bolt's multiple heads from the shoulders of the barrel.

As the bolt travels rearward, the extractor pulls the spent case from the chamber. Pressure acting on the base of the case from the ejector ejects the case from the ejection port. The bolt's rearward travel also causes the hammer to rotate back past the cocked position.

Now, pressure from the compressed action spring forces the inertia piece forward. This causes the action bars to begin their forward movement and with it, the bolt carrier assembly.

As the bolt travels forward, the hammer follows until it is arrested by the sear. Pressure from the magazine spring forces the magazine follower up and pushes a cartridge into the feed lips of the magazine. (Funny, but doesn't the rearward travel of the bolt actually pushes the cartridges into the magazine ever so slightly?) The bolt strips the awaiting cartridge from the magazine. As the cartridge rides up and along the breech face of the bolt, it slides beneath the extractor.

The bolt head then reengages the shoulders and the bolt's camming action locks the action; completing the chambering process and the firing cycle.

It is quite unlike the fixed stock FN-FAL or the M1918 BAR or M-16/AR-15 where there is a recoil spring or buffer in the stock.
That said and done, I guess the commercial BAR can be made into a bull pup hunting rifle.

Mr.Brown will you please send me those instructions for disassembly for the browning bar semi automatic.([email protected])

Thanks, Randall

Mr.Brown could you also send me that at ([email protected])
Also I have looked at some of the manuals posted and my bars dont have A "slide release lever", I know some of therm are at least from the 70s. Will those instructions still work. Thank you I will apriciate it I have alot of brownings that need a good cleaning.

I have an older Belgium BAR 30-06 with the trigger assembly removal fromthe stock side. I need disassembly instructions. I can find them for the newer models but not mine. If someone has them please send them to me.

Picked up a 1981 vintage 7mm Mag, but have no manual for it. Thanks for the offer.

Mr. JBrown,
I would appreciate the instructions for Assembly/Disassembly of the B.A.R. Please email to [email protected]

does anyone have jbrowns assy/ disassy link for BAR's? Emailed him and he has lost the link. Some other post do not seem the same as my rifle. Production year 1991. It appears the bullet is jamming in the barrel. locks up and when you get the unfired shell out it has a mark around the bullet just above the case neck as if the bullet base is to large. factory ammo,not reloads. any thought appreciated. thanks,deadeye

BAR Manual (http://media.browning.com/pdf/om/bar_98355_om_s.pdf)

Sorry,guys.I have searched everywhere for that set of instructions,I cant find it.However,I got them by asking Harley Nolden for them,just a few sections up.

November 4, 2009, 02:21 PM
update, just came from the range. grabed a handfull off winchester shells from a friend and they shoot perfectly. loaded up the remmington's and they jammed up as I posted b-4. so the rifle works as supposed to. do I just have a bad box/lot of shells? measured the base of both brands .284. are the tolerances so close that a .00025 to .0005 would make a differance? also could you take some emery cloth and reduce the base of the remmington shell to at least shoot for practice? thx

Does anyone have instructions for barrel removal?

November 16, 2009, 12:08 AM
the barrel isnt normally removed.

February 14, 2010, 08:55 PM
Mr. Brown,

I need some help on a BAR bolt removal. Do you still have the information available to remove them?
Thank you,

Hey guys, sorry to re-ignite an old thread, but I didn't want to muddy the "search" waters for those who may search for this type of thing going forward. I figured one less thread to sift through would probably be helpful. I've taken these guns apart a few times and know how to do it. What led me to post here on an outdated thread was that I've had a small issue with my 1967 made Belgian BAR. I believe it to be a common occurance that the bolt doesn't want to return to battery (let me know if I'm using that terminology incorrectly.) It would load another shell, but the bolt handle would not return forward as far as it should have. After that, I'd try to fire again, and nothing but "click." My SOP led me to rack the bolt back (figuring on a faulty primer or whatever.) This would obviously lead to problems, because the extractor wasn't engaged on the rim to eject the chambered round...so I'd wind up with one in the chamber, and one floating around in front of the bolt, not being able to go into the already occupied chamber.

This rifle, one of the earliest made was new to me in probably 2001. At that time that I got it, it had never been fired. It had some cosmoline type greasy substance inside the receiver, which I cleaned out as best as I could at the time. I went on to shoot it, periodically having the issue I described above. I figure the bolt mechanism was probably gummed up with the same cosmoline or whatever it was, and that this was what was causing the failures. Anyway, Saturday I took the gun apart to remove the bolt for a thorough cleaning to see if that would do the trick. I reassembled on Sunday and proceeded to test it out at the range. Problem solved. I filmed the disassembly procedure so I could show it to you guys so as to help out anybody who's having problems. Today, I left the cord that connects the camera to my computer, so I'll have to upload it tomorrow. Once I get it uploaded, I'll post a link to this thread.

In the meantime, if anybody has issues with BAR disassembly, I may be of some help to you all.

Hey, ARDog.....any luck with that video? Please send to me if you can. [email protected]
thx so much

November 15, 2010, 06:20 PM
I have found the instructions online.

Hasn't anyone ever heard of the NRA Firearms Disassembly books???? Fully illustrated disassembly instructions in the long arms volume; In fact, my copy has the BAR on the cover partially disassembled.
