View Full Version : Which lower is better, inch or metric?

May 09, 2008, 01:11
I have two lower receivers, one is metric, well worn, from parts kit. The other lower receiver is inch, a little better condition. I want to send one in to moses for trigger work. Which is considered better and for what reasons? Parts availability? Grip? sights (fixed Vs. Flip up)? The regulars on this site seem to be very experienced in the details, please give me your opinions.

Quality wise no difference. Parts availability wise not much difference either.

If the rest of your rifle is inch then I would use the inch lower. Using a metric lower on an inch rifle will give a sight height misalignment.

Only other point I can think of is that there are more furniture options for metric lowers than for inch lowers.

You could always just switch rear sights to get the correct hight.

Inch parts are the Brits "improvements" over the original metric FAL. Larger selector switch, sleeved trigger assembly, self-contained hammer spring/plunger, etc. But it really boils down to personal preference/convenience.

My reveiver and barrel are inch, so I need the flip-up rear sight. Is it an easy change over to put the flip up on the metric lower? I really like the metric pistol grip better.

The Inch folding rear sight assembly will easily fit on a Metric lower.

I use Inch style selectors (DSA) and Inch mag releases on all my metric FAL's. These are definate improvements to the original design. And I like the Inch folding charging handle on my Para, as this fits with the compactabily theme of this rifle.

But the Inch FAL just looks klunky compared to the Metric FAL.:biggrin: :biggrin:
