Anyone have experience with building on the Fulton single lug receivers? I bought one from Fulton and another off GB. both were very difficult to match a barrel to and the one off GB must be a second even though it was not sold as such. the one i got direct did finally work but the other is looking more and more like a paper weight.
I am using SA barrels, would that make a difference? on the second one, when you hand tighten it, the 6 o'clock mark is up above the 9 o'clock position.
I have heard nothing but good about the Fulton stuff, and everything else i got from them has worked just fine. i am thinking of just sending the receiver and bolt to them and buying one of there barrels, then letting them match up the whole thing.
Any help or ideas would be much appreciated.

First: A "single lug" receiver has the lug at the rear of the receiver under the serial number. A double lug receiver has another at the very front of the receiver also. The two legs on the receiver at the middle are not counted as "lugs".

2nd: I got two new receivers (unlugged) from Fulton two years ago. Both had casting voids, mold parting lines, and excessive flashing. I called and bitched about the crap quality. They said to send them back for evaluation which I did.
When I spoke with the lady on the phone, she asked if two "M1A" marked receivers would be acceptable. I said yes and they shipped me two new Springfield Armory Inc receivers that were fine. Shortly after this, Fulton pulled the plug on their receiver supplier.

3rd: barreling a M14 or M1 receiver is NOT like throwing together a M16/AR15. The M14/M1 barrel must be drawn down at the proper torque to exactly index with the receiver. This fit can be done by either facing off the "appropriate" amount of the barrel shoulder or rolling back the barrel shoulder. Obviously, this is done by a skilled machinist that has the proper tools. Anyone could purchase the tools and learn how to use them; however, you would have to do several jobs to begin to break even. The problem is not that you have a Fulton receiver. The problem is that the M14/M1 has to be barreled by someone with the tools and skill to do the job. Fulton should be able to assemble yours just fine.

Fulton is currently selling investment cast receivers from a new source.  The only review I have seen of them (on the FAL Files forums) was positive.  I have no other knowledge of them beyond that.

ArmyOrdGuy is absolutely correct; you will have to send your receivers, bolts, and barrels to someone who knows how to install an M14 barrel and has the proper tools.  If you don't know of someone already, I recommend Jon Tank, at Tank's Rifle Shop www.tanksrifleshop.com.

I just bought a Fulton receiver over Christmas and overall I am very happy with it. I will barrel it in the next week or so. My initial findings is that it should work just fine. Like the previous post said this is not like building a AR. These definitely require a bit of skill. Something that can be gained with patience and time.

Thanks for the input, this group is the best!
I do understand that this rifle is VERY different from  a m4/ar15 build, and i have read and studied the books, have the tools and the gauges. and this is not my first build.
It is just that the second Fulton receiver, aside from major blemishes, seems to be farther out of speck that most. all require head spacing and if not already done chamber reaming, bolt lapping etc. it can be done if one has the patience and the tools.
All the receivers i have had in my hand, when the barrel is hand tightened are within a few degrees of any other barrel and receiver. i have never had to have the barrel shoulder reduced or increased. (by shoulder i mean the part that contacts the receiver and prevents further tightening). is it common to have to work on the shoulder? have i just been lucky on all the others becouse they fit so well?
Thanks in advance,

All the building that I have done or witnessed was done on SAI receivers, and it was about 50-50 on needing to trim the barrel shoulder.  I honestly think that SAI makes a new receiver mold every few months sometimes, and the dimensions are all over the place!
