T2 is superior to the T1 in just about every way. I see used salty T1's still go for $550ish give or take, you can get a new T2 from Eurooptic for $650

I didn't realize how close they were in cost either. I'm guessing $650 is w/o a mount?

Its with the low mount, but you can still sell those for $50ish since people want them for guns like a HK SP5 (that's what I bought the aimpoint for)
$650 when added to cart, free shipping. Weirdly enough the no mount ones are more expensive. Eurooptic |

If you are buying an M4 mount, the Aimpoint one is a spacer that goes into the low mount, for lower third, but lower third spacer is still slightly lower than others.
It's a piece you add to the low mount. That's how Aimpoint does it. Then there is the quick release mount and there is also a quick release conversion for the low mount, but it is not as nice as the dedicated quick release mount. If you don''t need quick release, one additional spacer, Aimpint calls M4 riser or such, fits the low mount. I changed to longer screws in mine added a Daniel Defense lower one third riser on top of Aimpoint's M4 riser. I asked Daniel Defense how much to just buy the spacer and the customer service had the warranty department send me one free of charge. |

Took my newest built MK18 Mod 0 out today to zero and ran into major issues.
Built with all brand new Colt parts which makes it even more disappointing. Would fail to eject every few rounds. I think I got through 18 rounds at most during one test before it malfunctioned. Started the process of elimination by changing out the extractor and ejector but still did it. Then changed out the entire BCG with same results. Changed out the H2 buffer and spring for a carbine buffer with same results. Chamber is in spec and go/no go gauges test good. While looking everything over I did notice the paint splotch on the barrel under the FSB is not centered and makes me wonder if the gas port is not centered. This does not seem to be a gas issue though since the BCG is coming back far enough to try and pick up the next round. It has to be a barrel issue at this point thought.... Bought it brand new from Brownell's just a few months ago so I guess I will call Colt and see if they will send me a new one due to Brownells being out of stock. I'm the biggest Colt AR/M4 fan ever and this is not the first time I have been bit by them allowing something to leave the factory that shouldn't have. Hopefully they take care of me like they have in the past. |

Is an unfired round popping out of the magazine as soon as the bolt reaches the end of the rearward stroke of the bolt cycle so that when it moves forward to strip a new round from the magazine it is trying to shove two live rounds into the chamber? THAT is a double feed. Or, is it firing, failing to extract the spent case from the chamber and trying to strip an unfired round from the magazine and chamber it into the rear if the spend case? This is a "failure to extract". Is it firing the chambered round and not cycling the bolt carrier group far enough to the rear to eject the spent case or strip a new round from the magazine? Also a "failure to extract". Or is the spent case being pulled (extracted) from the chamber, yet remaining in the action and when the bolt moves forward it strips a live round from the magazine and attempts to chamber both the fired case and unfired round? This is a "failure to eject". Given the description, i'm guessing either a barrel or gas tube issue. I've seen gas tubes missing the bell on the end that allowed too much gas by-pass which resulted in short stroking/failure to extract or eject. BUT, that being said it could also be a multitude of minor fitment or tolerance issues. Rule out the little things first like an out of spec buffer detent rubbing on the bottom of the carrier, wear patterns that indicate the hammer impeding bcg travel, or even the bolt catch riding on the carrier. Also check the bolt lug/barrel extension lockup alignment to make sure the barrel is indexed correctly and that the bolt lugs are not impacting or chipping the edges of the barrel extension or being off index enough that the bolt lugs are rounding the inside edges of the barrel extension. Now i'm going to ask the question that so many hate to hear: where is the spent brass ejecting when it does eject? Direction from the gun and how far/strong does it eject? |

This is a "failure to eject"." Not going to be anything on the lower. It works perfect with multiple other uppers. Its a M16A1 lower with all new parts. Definitely a barrel or gas issue. Gas tube looks good its a new Colt. Barrel is indexed correctly, no chipping on any lugs. Strong consistent ejection when it does eject to the 4 to 5 clock position. Eye balling by looking down the barrel,, the gas port hole looks off center like the paint dot. I will pop the FSB off before sending it to Colt to see for sure. |

This one has me scratching my head, because if it were a misalignment of the fsb over the gas port, wouldn't running a lighter buffer and spring, or full powered ammo make some sort of a difference? And what paint spot are you referring to? The white spot they put on their barrels? Is that suppose to indicate gas port location? |
