Hi everyone, just looking for the latest suggestions for a reliable bolt carrier group for a stag 10. I don't have a budget in mind and am looking for excellent quality. Any recommendations, along with maybe some vendors that sell them would be greatly appreciated!

V seven if you have no budget!
Thank you so much everyone. Seems like most are highly recommended and work well!
enquiring minds want to know where you picked the kak up?
Just seen this on GUN AND AMMO TV.

The SureFire OBC is designed to greatly increase the reliability of an M4/M16/AR variant during both unsuppressed and suppressed firing. The OBC comes as a package with the OBC bolt carrer group as well as buffer and buffer spring. This patented design makes numerous improvements to the standard Mil-Spec full-auto bolt carrier group starting with delayed unlocking of the bolt during the firing sequence. This delayed unlocking is a result of a lengthened cam pin slot and our neutrally balanced counterweight. This delay allows expanding gases more time to exit the bore, lowering chamber pressure by 15%, which not only reduces wear and tear on parts, but also reduces back-pressure gases exiting the ejection port.
Next the shortened gas carrier key in conjunction with shorter buffer allow a 60% increase in stroke. This increase in stroke gives the magazine more time to feed, which can be essential as gas ports erode and magazines become dirty from austere environments. This additional stroke also provides smoother and more reliable feeding due to increased inertia when the OBC picks up a round from the magazine.
The previously mentioned neutrally balanced counterweight works three times in the cycle of operation. First the counterweight delays unlocking, as mentioned before. Secondly, the counterweight keeps the carrier group to the rear for additional time, allowing more time for reliable feeding of ammunition from the magazine and nearly eliminating bolt-over-base malfunctions. Lastly, this counterweight improves carrier and barrel extension lock-up, nearly eliminating bolt bounce. The OBC also reduces felt recoil, allowing for better tracking of sights and more control of the weapon when firing. Coated with an advanced anti-friction coating, the OBC resists friction during use and makes cleaning easy. For the ultimate in reliability, choose the SureFire OBC.
Features
Neutrally balanced counterweight automatically reduces cyclic rate, negating the need for switch or setting adjustments.
Improved cam path delays unlocking, allowing the chamber pressure to drop another 15% which permits more gasses to exit the bore
Nearly eliminates bolt bounce
Long stroke design improves reliability, allowing ammunition more time to feed properly
Utilizes Mil-Spec bolt and components
Anti-friction coating resists corrosion and makes cleaning easy
SF-OBC-556 comes standard with Optimized Bolt Carrier, Long-Stroke Buffer, and Improved Buffer Spring

The barrel manufacturer should state what length you'll need in relation to the gas port. With a barrel that long it'll likely be a rifle length. I put your standard rifle length stainless gas tube from brownells in mine. Also if you're doing a complete build seriously consider an adjustable gas block.
Also check out brownells for prices unless you're in a hurry, they have very good prices on items like triggers. You have to split order up into $500 purchases but it's usually worth it in the end.

+1 got the same one in mine, love the ease of cleaning with their coating

im running the toolcraft one myself in 3 rifles. no probs so far at all
Thanks again everyone for your help. I ended up going with the JP Variable Mass Stainless BCG, JP high pressure bolt and the JP silent captured spring. Everything fits but when I charge the rifle you can hear the silent captured spring, it sounds a little rough so not sure if normal however feels smooth. Due to brutal weather around here I can’t get out to try the darned thing.
