Q&A Session 1

This is the first session of LooseRounds.com Q&A.  If you have a firearms related question please email it to QA@LooseRounds.com. We will post the your questions anonymously and give you our answers.

1. Aimpoint vs. Eotech?

Howard:  Shawn and I advocate the Aimpoint.  While early Eotechs were a far superior optic to early Aimpoint, modern Aimpoints easily beat Eotechs.  Aimpoints like the PRO, T-1, and Comp M4 have superior battery life over the Eotechs.  An Aimpoint will run for years while an Eotech will run for a month on a single battery.  In a recent drop test by Andrew Tuohy of http://vuurwapenblog.com/ the Aimpoint beat the Eotech.  Eotech has also had issues with battery draining while the optic is off.  Lastly, for a home defense rifle you can leave an Aimpoint on at all times so your rifle is ready to go.  I would not want to have to turn on an optic in a hurry while in an adverse situation.

2.  Will the Colt 901 take any 5.56 upper?

Shawn:  The Colt 901 will accept any 5.56/6.5/6.8/300BLK/etc upper receiver that has a small front pivot pin hole(Sorry, no old SP1 uppers will work with out an adapter).  You will need to use a mag well adapter and change out the buffer and buffer spring.

3.  Aimpoint PRO vs. Eotech.

Howard:  Ignoring the vs. Eotech part that was previously covered, the Aimpoint PRO is an great economical choice for a AR15.  Running about $400 new, it comes as a complete package ready to mount onto an AR15.  At 3/4 max brightness it will run about 3 years continuously.  You can leave this on next to your bed, or in your patrol car and know that it will be ready to go when you need it.  You can quickly adjust the brightness to be appropriated for the ambient lighting condition.  While it runs off a less common battery, you get so much longer life out of each battery it would end up costing you less then if you use an AA battery model Eotech.

4.  What is the lightest bullet for the 1 in 7 twist.

Shawn:  You can go as low as a 40 grain ballistic tip as long as it is a .224 bullet and not .223 hornet diameter, because the hornet diameter bullets have a light jacket designed to explode at a lower velocity.  Hornet bullets will not stand up to the faster twist and higher velocity.  Any quality 40 grain load will shoot just as well as any quality 55 or 62 grain load accuracy wise.  These lightweight bullets are not over stabilized and will not blow apart in flight.  That myth is from the days where people used the older light jacket hornet bullets in the new higher capacity .22 caliber cases like the .223 and 22-250.
