Been thinking about obtaining a 22 conversion kit

[paleone]

I have not heard very many good things about these kits. I know spikes tactical makes a great whole upper that is very reliable, and they make a great kit. But a lack of funds dictates that I can only afford a kit.
How is the accuracy of the 22 rimfire out of a 223 barral with 1 in 9 twist ?
How is the reliablity as far as the action cycling without jamming ?
any info is welcome and thanks in advance.

My ciener kits are as good as my early spikes, accurate out to 50M.
Reliability is 99% after polishing the contact points. This is using cheap fed bulk pack. Win dynapoints have been 100%
All through a lwrc/6721 12.5".

I recently purchased a Ceiner .22 LR conversion kit that i've been using through my LWRC 10.5" upper without a single malfunction using BDM 27-round mags. Of course, I've only shot about 200-rounds through it so far. I also only shoot Federal 36-grain copper-plated HP (550-round bulk pack) which also give me the same POI as .223 55-grain rounds out to 50-yards. YMMV.
