Lantac Enhanced BCG-

[Send it...]

Anyone have any experience running one of the Lantac Enhanced BCG's? I believe they are nitrided and feature a few other fancy modifications like a domed cam pin, anti tilt carrier, and modified gas ports.

It seems like it might be trying to be in similar class as the LMT enhanced BCG. Which I think is for over gassed systems or to slow down cyclic rate- I'm not really sure.

If you have any experience with these, I'd sure appreciate your info.

Thanks, Happy Holidays.

I've never tried one, and I'm perplexed at what a $290.00 BCG will do for me, that a $150.00 BCG will not. That said, while shopping today I came across this sale. This price for a Lantac Enhanced makes much more sense than it's usual price point.

I have one. I’m not certain that it does anything noticeably better than a Sionics or whoever. I don’t consider it to be equivalent to the LMT. I haven’t had any problems, though. It seems well made.

Thank you both. A great price on that bcg, thanks for posting.

I've got a Lantac E-BCG (Fail Zero UCT coated), LMT E-BCG, and multiple LMT E-Carriers.

I actually use the Lantac E-Carrier in my SR15 upper. It's heavy, like a Young National Match. .3-.4oz more than my KAC M16 carrier. The LMT E-Carriers are actually .2-.3oz lighter than the M16 carrier. .5-.6oz lighter than the Lantac.

I got the Lantac for $150 years ago on super sale. I wouldn't pay full price for it, TBH. But it's been a solid BCG and I really like the cam pin. C158 bolt that saw a lot of suppressed SBR use. Still solid.

But it doesn't have any single feature that will significantly reduce or alter gas drive. The enlarged ports are actually beneficial, but those only affect the very end of the cycle of operation.... and, even then, not very much. The heavier carrier mass likely plays as much of a role as anything else.

It's a quality carrier with a really good cam pin and C158 bolt.

The A100/Aermet 100 bolt in the LMT is unparalleled. The entire E-BCG is legend at this point for shorties (especially suppressed shorties). I suspect Knights moved to that in their E3.2 bolt.... but that's my completely uninformed, wild-a$$-guess.

I also use the LMT E-BCG's 308 version in my suppressed AR10 and I'm really pleased with it. 165gr & 168gr Federal Trophy Bonded Tip run like butter with the LMT E-BCG.

Sionics NP3 BCG is the play, TBH. [emoji106][emoji106]

BTJ mentions the Lantac cam pin. I got one in over Black Friday sales. Something that seems like a good idea if the fit is snug. Have to drop mine in a carrier, and I’ll try to grab dimensional measurements.

My Lantac domed cam pins fit my standard LMT C158 bolts just as well as the LMT cam pins.

But you're correct, a tight fit is vital.

I once reached out to a nearby purveyor of NP3’d parts, with the intent of acquiring some spare parts. Using my BCM cam pin as the model, I provided diameter measurement to someone who said he’d happily grab some pins of equal of slightly larger size for me.
I never heard back. BCG, barrel, buffer spring - I am picky about these.

Yeah. I know the crew at Sionics basically went to college about NP3. Became subject matter experts on it as it related to their BCG's.

They are the only ones I trust for NP3.

V7's enhanced cam pin is the only other non-LMT/BCM/Colt cam pin I use aside from Lantac. Used that for thousands of rds as well.

how was the fit with the domed cam pin? I was thinking about picking one up.

I haven’t used it. It’s still in the baggie…. So far, I’ve just been trucking along with standard, complete BCG’s so just haven’t pulled it out.

The fact that they use NiB on their "enhanced" BCG already tells me its garbage. Id sell it or throw it into a training rifle.

Also saw they had TiN coated BCGs, guess Lantac just dropped to the low tier parts makers for me.

I'm curious as to what makes you say that. Lantac using a TiN coating isn't a big deal as they are simply making a product consumers are demanding.


All NiB coatings are not the same. Lead tungstate as the stabilizer in place of thallium sulfate results in a Gen 4 version which increases the content from 1-5% boron and 95-99% nickel, to 10% boron and 90% nickel. This also raises the Rockwell Hardness to 82, from a much lower RH of 54-70 (depending on how high the heat treat gets and what version is done.) Additionally, the newest generation of NiB is supposed to embed into the surface, as opposed to being only a top coating.

I know some people will argue there being a point to this as it is steel riding in an aluminum receiver, but we run parkerized BCG without trouble. The higher Rockwell Hardness and increased lubricity SHOULD make it easier to clean.

For me personally its associated with lower quality parts. There's a long list of trash tier parts from mfg that offer both NiB and TiN. Could Lantac be using a different process or extra QC to ensure that their NiB process doesnt cause premature parts failure? I don't know, but based on track record of other parts mfgs who tend to choose use NiB or TiN over other coatings or platings I wouldnt waste time or energy testing them out based on history alone.

I could be wrong and maybe Lantac has a very good reason for choosing those specific coatings over NP3 or Chrome, they do make some pretty good muzzle devices from what Ive seen, but personally I tend to stay away from mfgs who use those specific coatings.

Im sure markm will chime in shortly to rant about his experiences with NiB.
