I found out the hard way while taking a newby to the firing range and teaching them how to clear malfunctions from an AR15 if they couldn’t get the bolt back.   When I showed them how to clear the malfunction, they told me they were afraid to hit it hard on the ground because they thought they might break the stock, I told them to just got ahead and hit it hard enough to have the bolt fly back and they did.   When I checked the stock to make an adjustment on it, I found out that the stock was broken and I could not shorten it.  This was an AR15 that I built myself and very much consider it to be a hobby rifle, but I will not be putting hobby gun parts on it in the future.

I have no reason to deviate from using anything but the best for my AR15 hunger, the gun parts I have on my M4 rifles are what I like and it took me a long time to get to this point.   There are several choices to make for your magpul accessories and the most popular CTR stock is hands down my favorite.  I like the way the stocks lock   into place and they feel very sturdy.  I have done slam down malfunction clearances and never even cracked the stock.  I expect at some point it may break, but I’ve already got my monies worth.
