Guys, I bought a used AR yesterday and would like some help identifying if it is a complete factory Bushmaster rifle or a lower with a franken upper.

FSB reads: G02(R1)1 and does not have a bayo lug

Pretty sure this brake is not factory as the pin holding it on is far too wide and not centered to be something from the factory. It works great and reduces all muzzle jump while shooting offhand.

Definitely a HBAR. Yes, I know the handguards are not factory. They are First Samco polymer ones with rails under the rubber covers.

Underside of the bolt carrier. I couldn't find any markings on it.

Marks on the charging handle. These could just be scratches, but I wasn't sure.

2 and F inside the pistol grip. Hex screw has "YD" on it.

Let me know if there is anything else I could look for to verify manufacturer.

If anyone could tell me what the markings are, I'd appreciate it. Either way, I got a deal on the rifle and if it isn't 100% factory Bushmaster(other than obvious handguards and muzzle brake), I still made out well. It fires great - 4MOA with Tula steel case 55gr and 2MOA with handloaded 72gr. That was with the factory 12MOA front sight and gritty 8-9lb trigger.

Update:

Did some looking around and it is an Olympic upper with a Bushmaster HBAR. Still not sure about the BC or FSB/Gas Block.

The best thing about AR forums such as this one is there is always someone available to answer questions around the clock. That way if someone needs quick purchasing information it can be had fairly quick so nobody is ill-informed while dropping cash on an AR.

Glad you got it nailed down. Sell that BCG group to the first person who gives you 80 bucks for it, then buy a PSA or BCM BCG.

I agree.

What would you pay?
I paid $550.

Complete Bushy XM15 lower, Olympic upper with Bushy 20" HBAR + AK74 nine port brake, First Samco M44L handguards. No marking on the bolt carrier or bolt, I just took them apart.

I'm probably going to do some trigger work myself and put some NM sights and have a 1MOA rifle hopefully.

Why do you say it is an Oly upper?

Good point. And the photos he posted of the AR-15 were good. I'm always surprised how many people will mix and match not only uppers and lowers, but uppers and the barrels in them. Franken ARs tend to have lower resale value from what I understand, yet at the same time people at the gun ranges love to say "I built my own AR" with pride.

no more than 400$ IMHO. Thats just me though.

I am not being a jerk but before you dump 5 and a half Benny's on another one ask some questions before buying. I would have done 175-200 bucks for the complete lower and bought my own upper.

The segmented 'A' next to the rear sight on the right side. I got the info from here: http://www.biggerhammer.net/ar15/uppers/

All that means is it was made by Anchor Harvey Aluminum. Not necessarily Oly. :wavey: My 2011 PSA upper has the splintered "A" marking.

I understand and asked the guy and he said it came as is. He could have bought it from the guy who built it, or he could be the one pulling one on me.

Where could you get a 20" HBAR upper with a nice brake/BCG for $350? No, none of it is super performance stuff, and I'm not saying I got such for what I paid, but in my mind I got my money's worth and am happy. I'm a utilitarian type and from what I did with it at the range today, I think it could easily be a 1-1.5 minute rifle with trigger work and a $14 NM front sight post, regardless of the roll marks.

Also, why sell BCG for PSA?

Thanks for all the help guys. Feel free to keep the thread alive. When I get the chance to take it out to 500 I'll try to take photos of the targets and post them.

That's just the forge mark. A Splintered A is Anchor Harvey, They make blank forgings for everyone, so that doesn't tell you anything really.

Since you have a B marked barrel, I am going to say you have a Bushy factory rifle.

IMO $550 is a bit much, but if you're happy, that's all that counts.

Swap the hand guards out for some MOEs and maybe swap out that muzzle device and you'll have a nice stick.

Its not staked very well. If it is going to be a bench gun for accuracy then I probably would not be to concerned. If it were me...........I would put a standard muzzle device on, new BCG and standard A2 or MOE handguards. But that is just me.

"Each to his own!" said Stoner when he designed the Barbie Doll for Adult Men.......:tongueout:

Not going for the MOE simply because everyone has them or wants them. The ones on it now feel like I'm grabbing a pine tree trunk. They're HUGE, but not a priority to get new ones. I'd actually be fine with some standard $18 handguards as this is not going to have anything mounted on it other than a 1907 leather shooting sling.

What brake do you suggest? I was simply going to drive the pin out, shorten it to fit flush with the side of the brake, and put it back in.

I would probably have paid around $450 for it. But what is $100 in this hobby lol. So long as your happy that's all that matters. As for a brake, I've only tried a Rainier Arms XTC and I'm very pleased with it.

If that thing was mine, I'd throw an AAC Blackout non mount on there and the MOE handguards (They to me are an improved version of the viet nam era triangle guards and the AAC Blackout reminds me of the old 3 prong flash hider...) More of a retro "upgraded" rifle :) but that's just me....







Go buy yourself a few hundred rounds of Prvi Partizan and blast away. Keep well lubed and enjoy the darn thing.

Can't I stake it better myself? All I need to do is hit it harder where it's already been peened, right? Enough so it deforms the hex bolt outer face.

BTW, That might be an unthreaded barrel... so be cautious when tinkering. I just noticed the lack of bayonet lug.

G23Adam
09-16-2012, 21:36
And don't worry about the staking. It's fine. All you want is the metal to pinch the bolt a little. The ones with all the deformity goin' on isn't really doing anything but making it hard to work on in the future.

I'd ditch the brake and put an A2 flash hider on it. The muzzle may not be threaded though, it looks to be a ban-era gun.

Put a set of A2 handguards on it and call it good. An A2gery of sorts.

Shoot it some and save up for the next one.

If you really want to get into a true 1MOA gun, a good free-floated stainless barrel is the way to go.

I think this is what I'll do. :supergrin:

The thing is, the brake on it is actually a brake and not just a flash hider(is there any flash out of a 20"???) and directs quite a blast upward.

Here's a video of how little the muzzle rises.

I was off searching around for a buddy trying to find info on his bushy's serial and happened to find this thread: http://thefiringline.com/forums/showthread.php?t=315990

Note that the rifle pictured has the same brake as mine! Photo is hosted on bushmaster's website, so it would appear that I have a factory bushmaster brake on one of their barrels. the pin holding it on looks funny though. I'll get a pic.

This could be interesting. The serial on mine is L0313XXX, which reads as a pre-ban rifle in this list: http://www.ar15.com/content/legal/serialNumberList.html

I'm now pretty sure it's a complete bushmaster rifle.

This one is identical to mine as far as 20" HBAR, same brake, with no bayo lug: http://www.gunlistings.org/georgia-gun-classifieds/atlanta/rifles/34300/bushmaster_xm15

Square up and get a nice thumb over grip and it won't move at all.

You'll probably need more than NM sights and a trigger job to make that a 1 MOA rifle. At minimum you'll probably want a free-float set of hand guards.There is also a chance that because of the make of the barrel that you will never get the accuracy you want. For the best accuracy, a 1/7 twist with a heavy bullet is ideal. The muzzle device is pinned, and it looks like this rifle was set-up to get around a ban (if you say pre-94, it may be NY/NJ ban compliant.).

You should be careful what ammo you use. Many of the second rate companies have labeled barrels 5.56 and in reality they were closer to a .223 Rem (Bushmaster is notorious for this). The staking is fair. It will most likely hold, but if you want extra security, you can stake it a little more. There is a chance you are lacking M4 feed ramps, which may cause problems when using longer bullets.

My guess is that you have a post-ban Bushmaster "AK" style rifle. I wouldn't have spent money on it being that you could have a PSA for almost as much, but good luck.

:rofl:
Your neighbor's neighbor? :tongueout:

Wayax - It's got the M4 feed ramps and came from NY, so after all this, I'm pretty sure it's a Bushmaster factory gun. The guy gave me the original magazine and it is a 10 round non-disassembleable magazine as pictured in bushmaster's pictures of ban era guns.
