| My build is almost complete. I want a middy barrel because of less throat erosion & I think conventional 16 in barrels with a bayonet lug waay down the barrel look ghey. Would an Armalite or a CMMG work with a Bushy upper??? Thx. |

Two sources about middys from Small Wars Journal. I'll dig around for more.
http://council.smallwarsjournal.com/showthread.php?t=2258&page=3 “Just an update on the M4 issue. One of the criticisms of the direct gas impingement system in the M4 is that the smaller dwell time and excessive heat of the shortened gas tube causes premature wear and an increase in stoppages. The civilian AR guys have "broken the code" on this, and it doesn't involve a piston system. Extending the gas tube into a "mid-length" configuration appears to successfully address this issue. I cannot see why current M4s couldn't be retrofitted with a mid-length gas system. The conversion could be done with a total parts count of 2, and a cost per unit of around $30. You'd need a longer gas-block/front sight and/or a longer gas tube and something to protect it. The barrels need to be drilled; otherwise the conversion could be done at the unit level. I'm having a friend build me one, just to see for myself.” http://council.smallwarsjournal.com/showthread.php?t=2258&page=6 “With that in mind, the softer cycling and softer extracting mid length gas systems are a good solution for longer carbines.” |
