Ok, so I'll cave and rate several firearms; however, I will be using modified criteria and add a few extra things.
Swiss Arms Rifle
1. Performance (reliability, etc.) - 10/10 - Virtually unbeatable reliability in any number of conceivable adverse conditions.
2. Accuracy - 10/10 - Minute of angle accuracy with good quality ammunition.
3. Ergonomics (safety position, ease of magazine changes) - 8.5/10 - Excellent ergonomics, safety position, etc. The big let down is the magazine release and extra time to do magazine changes.
4. Handling (weight, balance, etc.) - 6.5/10 - It is a heavier rifle, and it is front heavy. This is the major let down, but is really unavoidable for a rifle of this type with a long stroke piston.
5. Reputation - 10/10 - Stellar reputation with both the Swiss Army and the multitude of Police/Security forces using SIG rifles around the world.
6. Longevity - 10/10 - Very long parts life for all components.
7. Durability - 9/10 - Designed to withstand harsh military use.
8. Design (how well thought out, innovative, optics mounting, etc.) - 8/10 - Uses a gas/bolt system very similar to AK rifles. This means high reliability and simplicity.
9. Aftermarket support (availability of accessories, etc.) - 7.5/10 - There are a somewhat limited number of available aftermarket parts, but parts are becoming more readily available.
10. QC - 9.5/10 - Issues are rare and usually minor.
Total = 89/100
Retail price = $3600
$ per point = $40.45
Swiss Arms Carbine
1. Performance (reliability, etc.) - 10/10 - Virtually unbeatable reliability in any number of conceivable adverse conditions.
2. Accuracy - 9/10 - Close to minute of angle accuracy with good quality ammunition. My rifle has always shot a little better than my carbine, but this is not really surprising.
3. Ergonomics (safety position, ease of magazine changes) - 8.5/10 - Excellent ergonomics, safety position, etc. The big let down is the magazine release and extra time to do magazine changes.
4. Handling (weight, balance, etc.) - 8.5/10 - It is only slightly heavier than an AR with comparable barrel length and handles well.
5. Reputation - 10/10 - Stellar reputation with both the Swiss Army and the multitude of Police/Security forces using SIG rifles around the world.
6. Longevity - 10/10 - Very long parts life for all components.
7. Durability - 9/10 - Designed to withstand harsh military use.
8. Design (how well thought out, innovative, optics mounting, etc.) - 8/10 - Uses a gas/bolt system very similar to AK rifles. This means high reliability and simplicity.
9. Aftermarket support (availability of accessories, etc.) - 7.5/10 - There are a somewhat limited number of available aftermarket parts, but parts are becoming more readily available.
10. QC - 9.5/10 - Issues are rare and usually minor.
Total = 90/100
Retail price = $3600
$ per point = $40
Ar180b
1. Performance (reliability, design, etc.) - 8.5/10 - The only issues I ever had were user related.
2. Accuracy - 7/10 - It shot well, around 2 MOA with 55gr bulk ammo. Acceptable for a rifle of this type.
3. Ergonomics (safety position, ease of magazine changes) - 7.5/10 - Very AR like but no bolt release.
4. Handling (weight, balance, etc.) - 8/10 - Lightweight and easy to handle. Not front heavy like the Swiss Arms.
5. Reputation - 6.5/10 - Has a decent reputation with sports shooters, but is not in use by military/police/security.
6. Longevity - 6/10 - Hard to tell as this is a commercial grade rifle. The only major long term issue I see is the polymer lower.
7. Durability - 6/10 - Polymer lower had some breakage issues, not designed for military use but for commercial consumption.
8. Design (how well thought out, innovative, optics mounting, etc.) - 5/10 - The polymer lower is an issue, as is several other features of the rifle such as a lack of bolt release and the design of the gas block.
9. Aftermarket support (availability of accessories, etc.) - 5/10 - Very limited number of accessories and they can be hard to find.
10. QC - 7/10 - Pretty good, but could be better. The rifle was designed to be an inexpensive alternative to the AR-15, so with this in mind, QC was acceptable.
Total = 66.5/100
Retail price (before it was discontinued) = $1200
Going price = $1500+
$ per point = $18.05
Adjusted $ per point = $22.56+
The reason I include a price/performance ratio is I believe it is valuable. There is no doubt that the Swiss Arms is the better rifle of the two (Ar180b vs Swiss Arms or any rack grade AR), but is the extra price justified based on what you will use the rifle for? That is for the user to decide. I went for the Swiss Arms (and sold my Ar180b) as I felt the price was justified, because I wanted the better rifle. Sure, the Ar180b could be considered a better "bang for your buck" than the Swiss Arms, but it is a mediocre rifle at best, and $1500 will get you an AR15 that is much better than the AR180b. The inclusion of such an index will reflect this.
