Need a cheap bolt carrier and bolt for a AR, used ok, where is the cheapest?
I'm hoping to find a set for $55 or less. Any suggestions?

If you need both you're gonna pay more than $55.


Bravo Company makes a great BCG for about $125 or $135.


Maybe you can find a used one, but I wouldn't know where to look.

Remember, you get what you pay for so don't go too cheap. Try J&T Distributing, they have good stuff and reasonable prices.

Not a quality build, has to kinda work. :D What's the going price for a used one?
The cheapest I could find was $80.

$80 for a complete bolt carrier and bolt is a screaming deal.

they typically don't dip much below $120 used (for M16 BCG's..... i'm not 100% on AR15 BCG's since I don't usually run them in my guns)

I got a new M16 BCG from Olympic Arms for pretty cheap, Like $125 or something like that

usually the new ones that are $120-$140 are not MPC, the better used ones run about the same.

A used bolt may not head space correctly.

A used bolt may not head space correctly.

I've yet to see one worn that badly.

I test all my builds with a field gauge and have only seen one instance where it even came close to field dimensions.

On the AR15, what happens if you have a tiny bit too much head space is that the shoulder on the casing will be blown forward slightly. If it is enough of a stretch for the metal then you get a ruptured case...

Steel cased ammo is a bit more prone to failure than brass cased ammo because it doesn't form as easily to the chamber dimensions.

It takes a LOT to make brass rupture from stretching.

When this becomes a real problem is when you try to reload the ammo. the stretched casings are thinner, more brittle and MUCH more prone to failure.

If you shoot brass cased ammo and don't reload, you could probably get away with a bolt/barrel combination that failed field testing and never see a problem.

I wouldn't recommend it, but it is NOT the serious problem that some people make it out to be.

and, like I said, it is VERY rare to find a bolt/barrel combo that will fail a field test.

It's your face behind the bolt. Spend what you want.

A BCG is the most important single piece with respect to reliability in an AR.

We can help you find cheaper, but you're asking for a miracle. Have you considered a Saiga? Barring that, find a used upper that runs. You'll have no problem finding a complete upper under $300, but it's a crap shoot as to whether it will work.

Can't find the $80 sets now, must have been a labor day sale and sold out.:( I'll shop around for a used or new MPC Colt set.

I'm gonna buy this $60 upper.:D

New prices for BCGs are almost always around $130. Spend once, spend right. It's the same as the argument for purchasing optics for your gun and why you wouldn't put an airsoft scope on your rifle, but much more important for proper functionality. Plus, the risk in a failure is much higher...

Don't go cheap here, this is the heart of your rifle.
Spend the money on a Bravo Co BCG or other top tier Manufacturer.
It shouldn't cost more than $130-$150 shipped.
