Car length Buffer Spring/Buffer in fixed length stock?

[kakpataka]

guys,
Can i use car length buffer spring( 11" approx) with car. buffer in a rifle length buffer tube? If not I ll need to buy these items . there was this big mix up and i ended up with car . buffer /spring.

They are different for a reason.

Don't mix and match, you'll have nothing but problems, and possibly a catastrophic failure.

Get the right parts, they are cheaper than a new lower, an eye, or facial reconstruction.

NO.
It's unsafe.

The carbine buffer will allow the bolt carrier to travel too far back into the buffer tube.
When this happens, the gas key crashes into the charging handle which jumps out of the reciever and hits you in the face.
It will also damage either the reciever, charging handle, charging handle latch or all three depending on how many times you do it.

Thanks guys.............
I was pretty sure I would be told not to but never hurts to ask.
I actually got the new vltor clubfoot fixed stock and ended up
getting wrong parts ( from someone & just the buffer & spring)
I went to the gun show in Sacto and no one had the buffer &
spring...
I guess I ll sell my Car length stuff here.

And on the same subject, I think I have the commercial tube
& not the Milspec tube. per Vltor, Milsec tube is required.
( again not my fault)However, the stock is fits just fine.
This stock is 5/8th of inch shorter that A2 stock
I think. I wont shoot the ar till I get the rifle length items but
if the stock is otherwise installed firmly with Comm tube, do I
still need to get the Milspec one? maybe the requirement was only
for their.
Thanks Guys..................
collasible stock?

i guess if it was an end of the world scenario you would throw a superball in the tube before the spring and buffer

or maybe a thread spool

Haha.thats funny! I ll be fine I am sure!!!!
I was on arf chat last night. I actually found the answer(
that is , not to try it ) from arf.com
via chat after I posted it here. One guys said to try it and make a video so that they can use it as a instructional videos for the members!

The AR buffer tube is 9 5/8" and the CAR is 6 7/8". You can add a 2 3/4" spacer in so the space in the A2 tube is the same length as the CAR. I have this set up in one of my rifles and it runs fine.

I have the spacer but the problem is that I ended up with rifle length tube!
I dont have the car. tube anymore!

don't mean to hi-jack this thread..
but if I put my 20" rifle upper on my carbine lower setup I'm asking for trouble?

is there a link to more info on the correct tubes, springs etc for different builds?

thanks

There's no such thing as mil-spec vs. commercial when you are talking about A2 buffer tubes.
All A2 tubes are made to mil-spec dimensions.
Carbine tubes come in commercial (larger) or mil-spec (smaller) dimensions.
A2 stocks are 5/8" longer than A1 stocks.
There's normally a 5/8" spacer used with an A2 stock on the end of the buffer tube.
ALL A2 buffer tubes are actually M16 (pre A1 or A2 variant) length.

What I was trying to tell you is to put a spacer (alum or wood) 2 3/4" long inside the rifle length tube to make the inside length the same as the CAR tube. Then you can run your CAR spring an buffer without any of the problems listed in the posts above.

TMC..................... I know what you meant! It made sense. its just that I ll have to wait till I get the stuff before I would shoot it! Hey can i use gummybears instead??? I must say it is a brilliant idea that you gave me though.....
for now. I just have my USP for the bad guys & believe me Sacramento has turned into crimeland so to speak.It is very unsafe here................ I am thinking of moving to Texas if I can find a job there.

Thanks and special thanks to Randal for always answering my questions!!

Randall, Thanks ........... I had no clue! I thought somehow that both car & fixed came in Mil & Comm. When I was looking for Car length tube though, the Comm was 16.00 & Milspec was32.00 plus shipping. No idea why such a price difference!

Mil-spec are machined from a forging (stronger, but more work to machine).
Commercial are made from extrusions.

I have also heard that you can stack a bunch of quarters in an A2 tube to make a carbine buffer work, but I have not personally tried that.
It sure would add a chunk of weight to the rear of the gun.

Interesting............. I do have some Romanian quarters laying around somewhere............ I ll use em instead! why waste US coins?
You guys are so smart..................and it never occurred to me.
I guess women can do that to a perfectly normal guy!
