V7 Weapon Systems

No, I have a bobro low rider sight for another build (coming soon) but this sight set is spikes tactical micro set. I wrote up some thoughts about them in the thread archived.

I was not very impressed with the Spikes sights in comparison to others but for a ultralight .300blk build they are great and the somewhat goofed adjustable elevation is still nice.

For comparison the Bobro sights each weigh .85oz for a total of 1.7oz.

I have a 2A receiver set that I need to build. I keep flopping back and forth between 223 and 300BLK...

Fill um up with V7 parts, match made in heaven!
I decided .300blk was the perfect round for this build because I didn't really have a reason to be building it other than dumping money into a pit of a lightweight obsession of a range toy. 300blk makes a sweet range toy, esp. suppressed, and since it is best to compound lightweight parts together when going ultralight the fact that the round is designed for sub-10" barrels means you can cut weight and length without making an abomination. Also the barrel-wall thickness for a given profile over 556 is less due to the larger caliber, which also results is less weight.

I agree wholeheartedly with the above. But, due to a couple reasons, don't want to SBR the 2A receiver.

I have been thinking about getting someone's lightweight can and having that pinned to a 10" or 12" barrel to give me a 16" oal. This way I'd have the short useful length of a suppressed Blackout and would only have to register the upper itself as the can.

The flaw in this from the lightweight standpoint is the internal diameter of the BCM handguard won't allow a suppressor to be slipped inside. Plan B is to do the same thing but use a short forend that stops where the barrel and suppressor meet.

That looks pretty damn loud.

I imagine so, I'll find out for sure tomorrow and when I can't take the punishment anymore with supers, I'll spin it off and thread on the SiCo Omega with subs write up to come.

It looks like it would be a pretty effective brake.

Shot it today, the brake shoots supers well and as the shooter it didn't seem nasty even in a concrete room. Subs shot real soft with the brake. Subs are real quite with SiCo Omega in place of the brake too! Full write and more pics to come: Project überlight

Awesome pics. I was interested to see how the V7 CH looked with the 2A upper.

Is that a Boomfab Titanium BCG? Thoughts on it?

Yes it is: 4.4oz with gas key. I think it is still the lightest carrier out there with the exception of JP Enterprises aluminum carrier, but i wouldn't go for an aluminum carrier on steel gas rings... V7WS carrier is a little more weight but less money. The Boomfab carrier is freaking expensive so don't spring for it unless you are also going to run the lightest buffer you can find (Tacom or Gutted carbine buffer) and are looking to compound the weight savings. Otherwise you would be better off with a slightly heavier Ti carrier like V7WS and make up the difference in weight with a lighter buffer.
