I got bored this afternoon so I replaced the OEM trigger guard on my Nork M4 with a Magpul Enhanced trigger guard.  It eliminates the sharp edges of the original part and makes shooting with gloves on much easier and more comfortable.  It also closes in the "gap" behind the trigger guard that can cause a nasty blister after engaging hordes of IPSC targets all day.  I opted for the quality aluminium product, rather than the new polymer offereing from Magpul.

That's it.  No more modifications.  Honest.

Oh....and I swapped out a bunch of Chinese parts with American parts that I had left over from my previous AR.  It certainly tightened things up a wee bit, especially the front sight post and detent pin/spring.  The Norinco front sight and detent pin had a bit of fore-and-aft movement to it.   I'm not happy with the tiny charging handle after using a PRI Gas Buster with Large Tactical Latch either.............must......resist......
