In my opinion the Swiss arms carbine with the 14 inch barrel is the best out of the box black rifle on the market for the following reasons.
-not too heavy
-the rotary drum sights are excellent, and offer night sight capability. The front sight is hooded and can withstand a lot of abuse before affecting poi.
- the SAN barrel can withstand 30,000 rounds at full auto before becoming useless unreliable on the battle field
- the magazines can also withstand 30,000 round cycles before needing replacing, so a single polymer magazine can last as long as the barrel
- the rifle is easily broken down for field cleaning (two push pins)
-different gas setting allow the user to continue firing even when the gun is seiously fouled
-the rifle is plenty accurate for battle
-the shorter barrel is easy to handle, offers greater accuracy than the 20 inch barrels as its stiffer and is affected less by the piston pressures than the longer barrel
-the gas system is longer than the cqb and sees exactly 1/2 the pressures the cqb sees which means longer reliable life, and less stress on the parts.
-if a bayonet and grenade launcher are necessary then a 17 inch barrel is availabe
-folding stock is handy for compactness, pistol grip is a storage compartment for knife, matches or spare ammo
rifle can fire 15,000 plus rounds dry, without lube
-trigger guard that moves out of the way when using gloves
-magazines are translucent saving precious time in assessing ammo volumes
-the material quality in the BCG, firing pin, barrel, trigger components, and even the springs is several levels above many other guns on the market today, which means less failures and longer lasting
All of these features are what are important to me in a weapon system. If I must go to battle with one gun, and have it last me from beginning to end, there is no other gun I would rather have than a Swiss made SAN. for me it would be the SAPR, in fact it is the SAPR, just not in Canada, yet.
