Review - Coonan - FAL Receiver

It grieves me that both DSA and Coonan have been putting out shit - it costs me a ridiculous amount of time and money to fix these defects. But the upside of it, is that I have been forced to institute pre-build inspection standards that help me determine patterns.

Coonan offers custom serial numbers, which makes tracking a receiver by the number difficult. But Coonan is now shipping receivers that have been back-ordered for 6+ months, so I can assume that a receiver recently shipped with a cutom number is from the same run as the other non-custom numbers.

I have three to enter at this time I want to get the text posted while it is still fresh in my mind, even though I will have more to add later. Particularly because one (not from the run currently shipping) is fatally flawed and Dan Coonan has already told the customer it's fine and he will not warranty it. This "f-ck you" attitude he first displayed on the defective L1A1 receivers - where he changed his published warranty to blame all the import parts for the fact they won't fit.



I am so angry I could scream. What it it with these people? If I made something that was bad, my ego would be so wounded that I'd immediately make it right regardless of the cost. It baffles me.

I know what your saying Mark I can't believe their attitude I mean why bother make them in the first place. If there was more at stake here you might consider a class action lawsuit but there's just not enough of these receivers being sold between both of the inferior company's.

Mark, your efforts and technical information are excellent. These findings are so disappointing! It's put me off wanting to build lately, disgraceful!

That's crap. So which one would make a type 2 receiver with the least amount of problems? In your DSA write up Mark the type 2's were the worst. Or would I be better off finding an older LMT type 2?

The difference is the defects in the DSA can be fixed. An oversize LS hole cannot be fixed.

I'm building a type 1 coonan from the recent shipment now I'll add it to the list later, but synopsis. receiver to long and no relief cuts = lockup fail - I added the relief cuts and ground the receiver back about .005". At which point I discovered I'd still not removed any materiel from the bottom right. Which means the back of the receiver was not only too long, but not parallel left to right. Hinge hole, BHO fail (flap sand) Everything else looks pretty good. LS hole appears fine but I won't headpace until later this morning.

Overall pretty good (so far).

Saw one yesterday, bloke bought it two years ago. Coonan type III, the only issue we found was a similar "BUMP" on the left front carrier railway, which kept the carrier from moving fully forward. The carrier would slide forward then bind about 3/8 inch. You could shove on it to make it close, but it lifted up and to the right a bit when you did so. I was reluctant to confirm which locking shoulder to use until the carrier would close on it's own, so he'll die-grind it himself and bring it back to complete his build.
He also has one of the DSA R-1 receivers, which went together fairly well. Which is a first for some time.

after dealing with that, check again if the bolt shifts right on closing - this will bind the extractor and is because the left rail is too wide. Dan told me it was a fixturing error during the machining.

So it's a defective receiver you say? Can't be, must be a defective surplus bolt carrier instead, along with the others carriers we tried .
