Default AR to .22 Bolt conversion help

I am looking to buy a .22LR conversion kit for my AR. Which brand is the best and which ones take the BDM mags? I am looking at the CMMG as well as Ceiner kits. Are there any others to be aware of? Also wheres the best place to find these in stock? Thanks alot for your help

Any of the kits based off of the Ceiner design will work with the BDM mags. Ceiner, Spikes, CMMG, etc

I was told to stay away from Ciener. It's a hit or miss. I bought a CMMG 22lr kit instead.

Go with CMMG or Spike's but not Ciener/Atchisson. Spike's will give you the best customer support of them all, but their firing pins are not compatible with the rest, which means that you cannot buy the BDM upgraded/hardened pin.

Go with the CMMG.
Please read the Calguns Wiki
Laws that forbid the carrying of arms...disarm only those who are neither inclined nor determined to commit crimes...Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man.

Default Spikes is great

I have a Spikes and love it. It shoots cleaner than the other types of kits (certainly much cleaner than the Ciener kit).

I bought a used Ceiner kit 13-14 years ago from a friend. It needed a new extractor (fixed) and feeds all standard and high velocity ammo. It does not like subsonics. Just keep it lubed and don't dry fire it. Highly recommended
