Anyone got any builds in the works?

Did an ultra lightweight build with only a couple of parts purchased for reasons other than weight, just put the finishing touches on it last night

Lower: Tennessee Arms Polymer Lower w/steel inserts; $42.99 5.6 ounces
Trigger: Geiselle SSA; $172, weight unknown
JP Capture Spring; $139.99, 7.2 ounces
V7 Buffer Tube; $48.50, 3.6 ounces
V7 Castle Nut End Plate combo; $43.65, 6.7 grams, 5.5 grams
V7 Hybrid Ambi Safety; $57.23, 9.7 grams
V7 Ultra Light Magazine Catch / FDE; $34.00, 4.9 grams
V7 Ultra-Light 8620 Alloy Bolt Catch Kit; $20.37, 9 grams
V7 Ultra-Light Take Down Pins; $27.28, 5 grams
V7 trigger/hammer pins; $17.00, 2.35 grams
BCM Keymod Short Vertical Grip; $39.95, 1.9 ounces
Magpul K Grip; $13.61, 2.4 ounces
Mission First Tactical Stock; $37.09, 5.8 ounces
BCM KMR Alpha 16in Enhanced Lightweight upper, fluted; $628.95, 3lbs inc/BCG-CH
BCM FDE BCG; $190
BCM Vltor Ambi Charging handle; $60.50,
Inforce WML; $126.00, 4 ounces
BCM FDE Nylon Keymod Rail; $7.44, weight unknown
Griffin Armament Minimilist Titanium Brake; $90.05, 1 ounce

Decided against using my Aimpoint, left it on my 300BLK SBR and put a Vortex Viper PST 1x4 in an Aero lightweight 30mm tube. Could have gone lighter with the BCG but I don't use anything but BCM BCGs. Could have gone lighter with the buffer tube instead of the capture spring but I am shooting suppressed, which worked out perfectly with the Griffin muzzle device needed for my Optimus. I went with the Alpha rail instead of the KMR because I was tired of waiting for it.

If you have a low profile gas block you won't have the retention ring for a drop in guard. Im 99% sure you won't have the delta ring either. I've never seen this type of set up at least, other than a railed gas block.

Post a pict of your current handguard

Ah. Never seen a setup like that

That doesn't give you many options for irons. I'd either swap out for a FSB or just get a free float rail if your goal is to set up iron sights. You don't really want them mounted to a drop in guard.

But even if not, I don't know that I've seen an extended drop in for something like that

You can cut the delta ring off. Not so much for the other retention ring on the gas block.

In all honesty any gun shop should be able to install a free float for pretty cheap. Wouldn't take them more than 10min. That would pretty much open you up to any handguard on the market

You think you can dremel the front ring off? Guess it's possible, just seems like it's fit pretty tight to the barrel to be able to dremel all the way through it

Also would have to dremel around the gas tube

They won't extend over the gas block like you wanted. It will be the same length as your current drop in guard.

Other than that, it will work
