You can use beam sabers from HG kits as a firing effect for the mega beam cannon.

The nose section's armament can be combined with the rear portion of the existing HG Lightning Gundam's rifle
to form an enhanced beam rifle.

The newly combined armament can also be mounted on the underside of the unit.

To combine with the HG Lightning Gundam,
first remove the vernier cover from the bottom and attach it to the top.

Then combine it with the HG Lightning Gundam the same way as the Lightning BWS Mk-I.

then bend both large verniers upward.

Combined with the HG Lightning Gundam in MS mode.
The center of gravity shifts heavily toward the back, so it's a bit nerve-wracking to keep it standing upright.

The mega beam cannon section can be folded forward 90 degrees and locked into the hole on top of the shoulder.

Together with the Build Custom Lightning BWS Mk-I.
Unlike the Mk-I with its sleek aircraft-style form, the Mk-II goes for a full vernier configuration focused on thrust.

The Lightning Back Weapon System Mk-II has been released as a Build Custom kit, serving as the follow-up to the Lightning BWS (Back Weapon System) — the weapon pack for the HG Lightning Gundam. The original Lightning BWS must have been quite a hit for an accessory kit, so it looks like they rode that momentum right into releasing the Mk-II.

Where the original Mk-I had a sleek aircraft-style form, the Mk-II comes with large verniers in a full vernier configuration. Combined with the HG Lightning Gundam, it gives off a vibe reminiscent of the GP-01 Full Vernian.

True to its nature as a dedicated accessory kit, this one comes packed with all sorts of extra features. It can combine with the HG Lightning Gundam in both MS mode and flight mode, and the nose section's armament can be joined with the rear of the Lightning Gundam's beam rifle to create a new enhanced rifle configuration. On top of that, the mega beam cannons on either side can be folded forward and locked firmly onto the shoulders, and they can also be used attached to the scope of the new beam rifle.

Just like the Mk-I, this is a pretty solid accessory kit to recommend if you already have the HG Lightning Gundam — but the sheer bulk of it means that combining it with the HG Lightning Gundam in MS mode makes it pretty tough to keep standing due to the weight. It also feels like the connection isn't quite as solid as the Mk-I's, and honestly, it's hard to top the original — so personally, I'd still lean toward recommending the Mk-I.

That said, BWS-style accessories are pretty rare in the Gundam world, so this is a fun accessory kit that can be used not just with the HG Lightning Gundam but with other kits as well. At the very least, it's got a much better look than most of the other Build Customs kits out there... :-)
