The M16 assault rifle's bolt and bolt carrier are made of steel.
PCD (Pitch Circle Diameter) is the diameter of a circle that goes through each of the bolt holes. You can find it by measuring distance from centre of one bolt hole to the centre of opposite end bolt hole...
A bolt.
On a five bolt pattern measure from outer edge of one bolt then across to the middle of another skipping one bolt hole( not quite the diameter). On six or four bolt patterns measure across from bolt center to bolt center as you would the diameter if it were a circle.
if the diameter 5/16 inches then you covert the 5/16 into 0.3125 inches. divide 5 by 16=0.3125 which is a little bigger than 0.3! ;)
The M16 assault rifle has a 7075 aluminium alloy receiver, steel barrel, bolt, and bolt carrier, and glass-reinforced polymer handguard, pistol grip, and buttstock.
measure the diameter of the hole for the speaker/subwoofer and the distance to each bolt hole to asure you get the right subwoofer to fit properly.
uh well there completly different guns...the m16 is a assualt rifle and the l96 is a bolt action rifle. m16 is probly the better choice if your trying to survive on a battlefield.
the bolt will remain open
2 1/2 ounces
This would be concidered the largest diameter,dimension of a bolt.
I would get a larger bolt. I would get a larger bolt. If I wanted to make a bolt fit into a larger hole, I would use a SMALLER bolt than the hole.
