My M4-Based SBR Build: Sighting System

The third assembly or system I have completed on my M4-Based SBR build is the sighting system. Rifles will be largely useless without a sighting system, and I have chosen to use an Optic sight for my main sighting system, and Iron Sights as back up. 

Total price was at Php 12,154 (approximately Usd 289), which I think is just about the same in the US, based on the prices of similar items that I have looked at in the internet being sold there.

‘Parts Breakdown and Details'
Here is a breakdown of the parts of the system, and posted alongside each are the prices and where I bought them (note that all the prices included Shipping Costs wherever they apply. If the parts came with multiple shipments, I just divided the Shipping Costs with the number of items that arrived):
- Burris Fast Fire 2 Reflex Sight, P 6,000 (Online, Philippine Pistol Forum)
- Picatinny Protector for Fast Fire 2 Matte Black, P 4,202 (Online, Ebay.ph -from US location)
- 45 Degree Offset Back Up Iron Sights, P 1,952 (Online, Ebay.ph - from US location)

My M4-Based SBR Build: Upper Receiver Assembly

I have completed the second assembly for my M4-Based SBR build, and it is the Upper Receiver Assembly. Total price was at Php 22,466 (approximately Usd 535). Again, by US standards, it is shockingly expensive, as it is almost the price of some basic M4 Rifles I have seen on US websites. 

But that is life here in the Philippines, where owning firearms is not a right but a privillege, meaning only those who can afford can legally get one.
