We get a lot of smaller questions sent to us weekly. So today I am going to rapid fire answer a few of the easiest to get the info out to those who want it.

5.56 green tip vs car door? Yes, M855 will go through a car door
What ammo for 1:7 twist? Any ammo is fine for 1/7 despite what you may hear or read otherwise, 1/7 will shoot as low as 40 grain all the way to 90 grain
winchester unertl scope? Winchester did not make Unertl scopes, Unertl is the maker not the model. Winchester did sell scopes but they have another name and were used some in WW1 and 2
Does a colt le6920 have a firing pin spring? No, the colt 6920 is the closest you can get to a military M4 and is milspec other then the barrel length and full auto. The 901 does use a firing pin spring.

does colt rail gun come with night sights? No, the USMC rail gun does, not the current civilian model. The USMC model will be sold in 2013
How are Super Sniper scope? SWFA SS scopes are generally considered good for the money. Their HD line receive excellent reviews. I owned a side focus 10x and thought it was very good for a cheap scope. I also owned a 5-20 and thought highly of it. However SWFA has been criticized for how they have been handling some sales and preorders.
how to modify 25 ammo for better performance? We highly recommend against modifying factory loaded ammunition for self defense. Modified ammo can have various issues from poor feeding to blowing out the center of the projectile when fired, and leaving a ring shaped section of the bullet in the neck of the barrel. As for .25 ACP, often a round that has good penetration is recommended for self defense. A large part of ammo selection for the .25 is finding what will work reliable in your firearm. The various 50gr full metal jacket rounds from the major ammunition manufactures are what is often recommended.
