B29 , your email was received and returned, twice. It is customary to state your intent on purchase when replying to an ad. The first one to post "I'll take it!" on EE gets the item.
The four pistol grips are sold and already shipped. Two of the handguards are still available.
If you are interested, please IM me. Your email doesn't seem to be working.
I might be able to dig up some more pistol grips with screws from a friend if you want them.
I'm not sure what he will want for them. But I will check tonight and let you know if you will IM me.
That way things may come out for both of us - you'll get some grips and I'll sell two of the handguards.
Again, please IM me.
