G&P WOC AR15 Basic Kit
 

So i am undertaking the challenge kit. Reading reviews on it I find it to be a good weapon but a few of the stock interanals that come with it seem to be lacking. Does anyone have any suggestions on what parts should be replaced right out of the box with steel parts? OR is this a case of. Buy the kit let it sit while you pick up all the replacement pieces then assemble it with the new after market pieces? :?

I have a GBB King Arms M4 and AGM M4. I found that the components in the trigger housing get the most wear. With the AGM M4 the sear will be the first to wear out, then the trigger and hammer. The bolt catch may wear over time, however, it is the edge of the bolt carrier that gets rounded off.

I believe the G&P Challenge kits use cast aluminum parts (Better than the King Arms and AGM Zinc Alloy parts) so they will be more durable over time.

Personally, I think you should use it until something breaks, then get a set of replacement parts.

Hey thanks for the advice.

When they do start to break, G&P makes steel parts along with Prime

Ya i was looking at all the steel pieces. I know out the box i am replacing the front grip with a floating barrel RIS system. So that i can have room for attachments.
