Does anyone have one of the older Bushmaster fixed collapsible stocks used on the ban compliant M4 models? If you

do,does it have a rifle or carbine length tube, buffer, and spring? Thanks

I have one but, to tell you the truth I'm not sure what the difference between the rifle and carbine is.  

Let me rephrase that, I know the difference between a carbine and a rifle. I don't know the length of the carbine tube, buffer, and spring vs the rifle

carbine buffer http://www.midwestgunworks.com/page/mgwi/prod/bushmaster-parts/F1000394

 

standard buffer http://www.midwestgunworks.com/page/mgwi/prod/bushmaster-parts/F1003081

 

I put a carbine buffer and spring in my build but I think it needs standard length parts.

I just checked, mine has the standard buffer

Thanks, I think that is why my rifle is not working.
