Ar barrel instal help

[SIKwitIT]

Do you just slip it into the receiver and tighten up the barrel nut? Any lock tite needed? Also i got a BGC from bravo company, it came with a small black o-ring, where does this go? Thanks

You're going to want a barrel nut wrench if you don't yet have one.

[G-forceJunkie]

Antisieze or grease on the threads. Tighten to 30 foot pounds + whatever else it takes to line up the gas tube hole. The oring goes around the spring under the extractor on the bolt.

The BCM BCG isn't fully assembled? You have to strip the bolt and put that o-ring in?

[Omega13device]

No need to use the O-ring on the extractor unless you're having extraction problems. This is typically only an issue for SBRs and machine guns. "If it ain't broke, don't fix it" applies.

G-force is correct on the barrel nut, just a bit of grease or anti-seize, no loctite.

its fully assembled, the crane o-ring is there just in case you need it.

Yeah only use loctite on knights urx iii (maybe other knights rails).

Other then that avoid it like the plague.

On the barrel nut i use Anti-seize and you can see in my video from the Midwest SS install guide.

good luck

the carrier was attached to the barrel, i looked in the tube it came in and no extra broke parts.

i used a tube of car axle grease a buddy had lying around. Make sure you check the headspace after installation if it isnt a factory matched bolt....you can never be too careful.
