How to tell if my m305 receiver is within spec or acceptable?

[isebsi]

Can anyone educate me on figuring out if my m305 receiver is acceptable for a hybrid Chinese/ idf build? I want to send out my receiver to get the markings removed and placed on the heel of the receiver. But before I do that I want to insure that I'm sending a receiver that is close to usgi spec.

Any pointers would be greatly appreciated!

check out m14medic he gives a brake down on how to check your receiver to see if its a good candidate for the build

Sadlak in BC sells an inspection kit to know if your receiver is milspec. Mine is apparently.

Awesome thanks John, I'll have to try this when I get home. I actually intend on sending you my idf parts kit and receiver to do a full NM build, but I just want to machine the marking on the Heel before I do so.

I saw on the other thread that you have machined the heel on the hand select Chicom receivers, is that a service you provide? It would be nice if I can do a one stop shopping.

I use a business (non-board business member) in ON, who does (IMHO) an excellent job. The lead time for the recievers I did was close to 3 months.

The blanking, heel stamping and parkerizing etc adds about $500 to the cost of a build. The receiver would have to be annealed, machined, blanked, welded, refinished, engraved and the re-heat treated and then finally re-park'd. The rifle could then be assembled. The recievers I use for this process are pretty much the "best of the best". All of the ones I've done to date were 2009 poly-tech recievers (with one exception). My next batch is going to be 80% '09 polys. About 75% of the Chinese recievers I see are "in spec" enough to be worth the effort, again IMHO.

I would be willing to handle all of this for you, but the costs for the work would be passed on to the customer and the turn-around time would be quite a bit longer than my norm.
