the AR6.5CREED will work with any of the Creedmoor wildcats. Most of the AimShot arbors do not have a neck, so they can be used in any wildcat or SAAMI caliber that is based on the same cartridge. So yes, the 6.5 Creedmoor arbor will work in the 6mm Creedmoor
AimShot has consolidated all of the same family of cartridges. So the latest ARRSUM will fit the RSAUM (Rem Short Action Ultra Mag) calibers as well as the RUM (Rem Ultra Mag) calibers.
As mentioned, AimShot uses a modular system for laser bore sights. We use a single high quality 223 laser (available in a variety of options, red or green laser, internal or external battery pack, etc) for the laser for all of the calibers. The other rifle calibers utilize a hollow shell, or "arbor", that fits over the 223 laser to provide the precise fit for each caliber. The advantage to our system is you only have to purchase one laser, all other rifle calibers are the "arbor" to fit over the laser. All parts are machined to SAAMI specifications of brass for long life and no chance of damaging your chamber and for the best fit. Out 223 lasers are engineered to be more precise than the competition since you are using a single laser for every caliber.
The 45/70 is the only rifle caliber that uses the pistol caliber bore sights since it was originally based or similar to the 45 Colt/Long Colt. To bore sight a 45/70 you would need one of the AimShot 30 carbine laser bore sights (MBS30 is what we recommend) and then the AR45Colt arbor that fits over the 30 carbine laser and fits in the chamber.
In order to use any of the AimShot rifle caliber arbors, you would need to use the AimShot 223 laser bore sight. We recommend the MBS223 which is the 223 laser with the modular battery options (internal watch batteries as well as the external battery pack with 20+ hours of use from 2 AAA batteries). The arbors are designed to slide over the 223 laser and then that is fit in the chamber for your bore sighting.
AimShot does now offer a bore sight solution for 338 Lapua. You would need one of the 223 lasers (we recommend the MBS223) and then the AR338LM arbor to fit over the 223 laser. This is then inserted into the chamber for your laser bore sight.
Unfortunately there is not a AimShot Universal Arbors for Laser Boresight for 375WIN. I recommend using the laser boresight at the link below.

Yes. The 444 Marlin is essentially a lengthened version of the 44 mag so the 44 magnum/special bore sight will work. For bore sighting you will need the AimShot 30 carbine laser bore sight and then the AR44SW arbor to fit over the laser and into the chamber. This will fit the 44 mag, 44 special, 444 Marlin, and a few others based on the same cartridges.
We do not currently have an arbor/bore sight for the 450 Bushmaster. It is one of the calibers that we are considering in the near future but for now we do not have one.
