mark of the beast

i have a 2012 s12 that has 4 clear ports, it would fire winchester universal with maybe 1 in 10 shots being a fte. After doing a conversion with parts from css the same shells will not eject at all, i believe the tapco g2 is causing excess hang up pressure on the hammer face. I am thinking i need to have some reprofiling to cure this. Am i on theright track? Any suggestions?

I am hopeing someone can give me detailed info on how to attach the dust cover to the rear hinge portion on my chaos titan rail. thanks

I would like to hear any info from people that have tried the extended handguard from texas weapons systems. pros and cons. thanks
