Forgive me for saying, but if you are a actually serious about questioning applying loctite as per manufacturer specifications because of the cost, then I would humbly submit that maybe you should re-consider owning quality rifles like CZs and stick to Mossbergs and such.
Having said that, I understand that sometimes life throws us a curveball and every dollar counts; so as a fellow CGN'r I will offer to send you loctite free of charge. No joke, no judgement, just pm me your mailing info and I'll send you enough to last you a very long time.
Cheers.
