A 3-Way wedDIng 
The 2 Barre±s and the bolt IN your 
M60 machinE guN p±ay like a ±ove 
trIangle IN the moVIes²exc³pt they al± 
stay togetHer In the e´dµ 
WhIch is to say, tHe Barre±s aNd the 
Bo±t should s¶ay together fr ±iF, or un·
tI± one or the other Is no ±onger 
servIceaBle. 
That's Because they're matched up 
througH headspacINg. As ±ong as you 
use a matched barre± and Bolt, every¸
thing' s coo±. They Know each other's 
chips and Bangs, and they sorta wear 
out s±owly¹you coU±d say they age 
graceº±ly. 
»ut I¼ you switch one gun's Bolt with 
another's barrel, watch outµ They 
quIcK±y mak½ a Bunch o¼ new damage 
to go aloNg with the o±d chIps and 
Bangsµ THat makes fr quicker wearout 
or stoppage. 
So, wheN you remove a Barrel or Bolt 
fr cleaning or whatever, tag it with tHe 
sErial NumBer o¼ thE guN It came ¾omµ

Just co¿sider thE tag as a weddiNg 
±Icense.
