[ARCHIVED THREAD] - What kind of free float rail adapters can I use on this upper?

Posted: 1/1/2004 8:23:12 AM EDT

I have the following upper on order:

http://www.bushmaster.com/shopping/uppers/post-ban/pura2b20.asp

In case you can't use the link (bushmaster's site times out alot), it's an A2 20in Post Ban National Match Target Model Upper Receiver.

The carry handle and site are fixed (A2). I wanted an accurate 20" rifle, I hope this is it.

But, I still want a Knights or arms system. Or maybe there are other alternatives. I've seen some cool stuff around, and there is always custom right?

Now, that A2 front site - I don't know that I should be taking that off myself to slip a free float tube on. Do I need to? Maybe I would want to send my upper to someone to put it on for me.

Thanks for the help in advance!

Sounds like a good unit, what did it run you? Personally, I'd shopped around for a barrel (whatever your flavor), then ordered the Free Float rail tube you wanted, and has MSTN or a reputable smith complete your build to your specs. This will most likely incur more expense, but you would'nt have to remove front sight posts (I hear it can be a pain), and modify your pre-built BM unit. Congrats on your new project, I'm interested in hearing how it turns out.

I personally like the Knights Long FF tube, w/ flip up gas block. MSTN also has other great FF tubes as options.

I bought my RIS, mounts, and aimpoint from MSTN.

I've checked out there site, but they don't really tell you which system works for an A2 20" rifle.

I bought it from Bushmaster. I maybe paid more then I should buying direct...I guess, I just wanted to make sure I got what I wanted, and it was easy to order from their site.

I also had them permanently attach the ak break. I had thought about getting a benny (bernie?) cooley is it? From the jp site, but I didn't. And now I sorta wish I had ordered a Krebs AK break. But I didn't

Still, I'm excited to get it. I wan't to get the free float put on before the summer.

When it's done, I'll get my brother to take some pics of both my ARs so I can put them on the pics thread.

sorry if this is against forum rules, but...

*bump*

I really am looking for an answer to this question, and I've had so many beers tonight, I thought I'd risk bumping my own post.

Well, you aren't gonna like this, but most FF Tubes such as Knights and I beleive most other Mfg's (not sure about ARMS), require the front sight post and muzzle brake/flash hider removed for install. Maybe someone will chime in to verify or counter this. So if you want to mod your inbound BM Post-ban 20" A2 upper-w/perm attached AK brake, this summer w/ a Free Float Long tube from Knights (typical setup for 20"), then there is some work involved. There are probably some other Manufacturers out there that have something which will be work out for you just fine, I only have used Knights FF tubes.

doh, you're right, i don't like that.

I need a free float tube.

I ordered that bushmast mid december, maybe I could call them, and stop them from getting too far on it.

I'd cancel it outright, and order just the barrel w/out front sight, then shop for the other parts, more flexible this way. Call and ask BM, if you sent them a (brand XXX) FF tube, could they do the install. Good Luck

well i can't cancell it outright.

I want that upper bad.

i'll call them and see what i can do.

if they can do nothing, it will stay as is.

i want that upper so bad i can taste it.

and I'll add:

and it tastes like beef (or chicken), and it's whats for dinner. eat beef!

brought to you buy a guy whos income depends on the small grain crop and the flour and feed milling industries.

It's going to be a job with that brake perm. attached. If you can modify the order and want that upper, then I would have them cancel the brake. You don't need a brake perm. attached on a 20" for legality, and you can have a brake put on later if you so desire. However...the other replies are correct, you aren't going to be able to put a rail system on the gun the way it's coming in now. Without the brake on there, you can just punch out the pins and remove the FSB and put on any floater you wish. If it were a flattop you of course could still use an ARMS 59 even with a brake, but an A2 leaves you no options. Sorry.

Edited to add, I forgot that you didn't want to deal with removing the FSB yourself. No problem, I or any of the other dealers on the site should be able to help you get the floater on, but it will be much cheaper for you without the AK brake on there.

I lucked out.

I just talked to Bushmaster, and they said it shipped on Wednesday, but they did not permanently attach the break as there was no reason to do so. It's pinned and he said it would need to be heated with an acetelyne torch, but it can come off no problem.

So does that give me more options?

Thanks,

Gives you basically any free float tube option you want, that's cool.
