Bushmaster XM15 probably from the ban era.

Anything's possible, but all factory A2/A4 Bushmasters that I've seen came with the standard A2 flash suppressor. That muzzle brake looks aftermarket. Also looks like your carrier key needs to be staked.

Yeah, it might be easier to just buy a staked one, and this one for a backup.

The ban ended in 2004. Were flattops a thing yet?

I bought two ban Bushmasters around 2000 and they both were flat tops with removable carry handles. I still have one of the lowers

The add says permanently attached brake, this one may not be permanent because it has a pin and likely not threaded.

Yeah, it may well not be the "Shorty AK" but I posted this because someone mentioned it.
I do (vaguely) remember the AK style brake being offered separately in their catalogue.

The L prefix with over 100k num is well into the ban time frame. If I remember correctly, L prefix and under 50-51k should be preban, there was a lot of question on complete guns in the 50-55k numbers. The issue was there were just receivers and not complete. The shorty AK's where actually good running guns, despite the experts here saying otherwise. Bushmaster was pressing and pinning the Y comps and AK brakes mainly due to the NY market as they specified, no threads underneath.

You wonder if the "Bushmaster" brand will make a comeback at some point.

I think only if the current Windham and some former Bushmaster guys believe it would be profitable.

Looks like a shaved off bayonet lug too. Definitely ban compliant for something

Aha no threads

Yeah I had a flat top “ban bushy”...just crowned on the end

The “Shorty AK” was available as an A2 or A3. The AK74 style brake was permanently attached, and brought the 14.5” bbl to the legal
16”. The carbine was sans bayo lug.
The 74 brake was available on other uppers with different bbl lengths from Bushmaster.
The Shorty AK was fine, just stake that carrier key, and definitely put a BCM (or equivalent) extractor spring and buffer in it, and it’s good to go.

Those muzzle breaks were offered by Bushmaster as a standard catalog item. They were very common on 94-04 ban era rifles. The carrier key needs proper staking after ensuring the screws are properly torqued.
