Just got back from running drills in prep for BRM. The M16 is horrid and I have more reasons after spending more time with them today (M16A2s).
1. Has little pieces that can get lost on the ground during takedown, such as the firing pin retainer and cam pin. No AK or SKS or any other piston gun has itty bitty pieces to drop and lose that are critical to the weapon's function. Smallest piece is the op rod or op rod spring, which is two inches long.
2. S.P.O.R.T.S. reminds us all that the rifle dumps crap back into the receiver to the point where you have have to jam a round into the chamber sometimes. ( any gun can malfunction and I understand that)
3. A broken stock puts the weapon out of action.
4. Said stock is not exactly sturdy
5. Ratcheting burst is crap. Will it be 1,2, or 3 shots this time
6. 5.56 ballistics are inferior to .308. Yep, I said it.
Many countries use it only because we hand them out like candy to other countries as well as NATO standardization. I'm not going to knock it without proposing an alternative or two so here I go.
and my favorite.
It takes m16 mags, piston upper, and the stock isn't critical to function.
