Advice on drop-in carbine handguard needed

[dacron]

I wanted to have simple solution, I understand drop in has disadvantages however its pro is simplicity of installation. FF requires couple of tools I don't have. I might settle with change of rear sight as for now and opt for FF in the future as I feel i would be proper solution in the long run.

ALG rails install with a proprietary system and include the tool to do so. You can remove the factory barrel nut with a pair of channel locks. Or use to, either way its a $7 wrench.
