Are all FAL receivers the same dimensionally? Are they like an AR? I want to replace the fire control parts of my Entreprise FAL. Can I use any FAL guts for this gun or do I have to buy parts specific to the Entreprise? I believe this is a metric receiver.

Thanks alot!

There are some gotchas unique to inch vs. metric, but generally the parts are standardized.

This.

As far as I know you just can't use inch FC parts in a metric lower and vice versa.  Aftermarket metric parts are much easier to locate than inch FCG parts.

ETA- some of the aftermarket parts are good, some aren't.  I am no expert but I know that.  If I wanted a well made set, I'd get a military surplus set if I wasn't looking for some kind of target trigger.

Why do you want to replace the FCG?   If it works, then stick with it.

And yes, you'd have to get a metric set if your receiver is metric.    If you do replace, try to find original parts from FN or IMBEL.

My parts were changed a bunch of times and its possible there is a mix of metric and inch parts in it. It had been malfunctioning and I finally found someone who can repair it. Its getting a make over as we speak with some new parkerizing and all new internals.

It is unlikely that there is a mix.   You may have incompatible metric parts though.

How was it malfunctioning?

Be wary of those that can "fix a FAL".   There are hundreds of horror stories of "gunsmiths" ruining FALs.

good point on going back to why you want to change them out.  

I am not the end all be all fal guru but in discussions and in my personal parts swapping experience...the FAL trigger has limits on what you can do to improve the trigger pull.  

My experience is with the inch type.  You can only go so far with swapping springs to lighten the trigger pull before you get failures to reset the trigger.  You'll get to fire once and find your gun with a dead trigger.   BTDT after de Century thumbholing a gun and didn't have the correct spring (century used an over length chevy coil spring) and I was using different gunsmith coil stock spring samples to get up and running.  Let's just say i had a lot of nice springs for good trigger pulls that didn't reset the trigger with live ammo.  Down the road on a parts order i bought the OEM spring to be on the safe side.

What you can do, check your parts to make sure the engagement surfaces are square, not chipped, and any pivots are on straight pins and the parts have non egged out holes for the pins. Too much slop is bad and yields inconsistent trigger pulls, more so with a slightly bent pin.  BTDT with garands.   if the parts are out of spec with loose holes or out of square, throw them away and get new ones.  If they are just rough surfaced, one can LIGHTLY give them a FEW strokes on a stone.  A light dressing not a drastic polish job or a reshaping.  Even with my description and caution it may be better to just leave them alone.

go over to FAL files and do some searches on match triggering a FAL.  Put your asbestos underwear on.

Another edit- you will find more fouled up trigger parts in the commercial category compared to the military unless someone tried to "improve" the military part.

Go to the Arizona Response System web site. Mark Graham tested many FAL receivers: some are good and some not. Just like any mechanical device, tolerance is the issue. I will not mention names here
