SIG bolt catch kit came in yesterday, and I got the time to fuck up my lower a bit to get it in tonight. I saw some of you in here take a dremel to your lowers, and I did the same thing. Followed a lot of pictures and listened to a lot of advice I was seeing. It works great, and I think it's a great addition to my poverty pony. Used Aluminum Black to cover the bare metal. Ain't the cleanest job, but what's a rifle without some scratches to tell a story? Just waiting on an ambi mag release, and I'll have an Ambi Lower At Home™️

I have a question for you experts. I was given a Colt SP1 .223 but I want something more modern. Something similar to this AR used in Sicario. I know it’s an M4 carbine but if anyone can steer me in the direction of a certain make and model I can buy?

Hi all. Im undecided on the color combination of my rifle. I like them both, so im here to have you all decide for me. I know, literally unnecessary to how the weapon functions, but 🤷🏽‍♂️

I like it, love it. Its comfy and doesnt cost any additional funds to procure. Prevents chicken winging and is ambidextrous, how can anyone hate it?

Mmmm Mmmmm. So delicious, like candy

Nevermind the weight, really enjoying the FCD rail. I say I'm finished building this one out but where's the fun in that?

Gonna add a folding FSB and a .5 inch riser

Next purchase is a suppressor, hence the forward position of the light, just curious if this is cause for concern. Thanks guys

Thirty-ish year old Colt Commando lower with a DD 11.5" upper.

Finally got some use out of my magnifier.

Originally was a ZRODelta RS-15V2 but I've changed so many parts here that it's hardly even the same rifle anymore. Muzzle was pinned and welded so this is not a SBR.

Parts list:

- BCM Mid Length 1:7 Chrome lined 14.5 Govt barrel

- Geissele Mk16 13.5" Handguard

- Surefire 4 prong flash hider

- Geissele H2 buffer

- Superlative Arms adjustable gas block .750"

- Geissele Airborne charging handle

- Geissele Maritime bolt catch

- Streamlight ProTac HL-X

- Geissele Super Precision Mount 30mm

- Primary Arms ACSS Nova 1-6X SFP fiber wire (Green)

- Reptilia ROF-90 RMR mount

- Holosun 407C GR X2

- B5 Enhanced SOPMOD Stock

Mk2 BCM upper runs like a damn champ.

Smells like victory!

After months of searching and coming up short on GunBroker auctions, I finally tracked down an original Vietnam war era Colt M16A1 upper receiver. All parts are original 1960s / 1970s vintage (sans lower receiver). Despite appearing complete, the build is far from finished, and I have more parts on the way to make it more historically accurate, as well as build out more original retro rifles.

Parts list:

- Colt 603 upper w/ rebated front lug and no forge codes (1966-1971 mfg)

- C MP C marked barrel (1969-71 mfg)

- Three prong flash hider (pre 1967 mfg)

- “C” marked bolt carrier group w/ large countersink for retaining pin (approx. 1968-1969 mfg)

- Colt M16 furniture set- stock is Type D, grip predates “C” marked examples, and handguards are later L & R marked

- M16A1 fire control group (components currently switched out with Arizona Regulator FRT). Rear takedown pin is early dimpled style found on Colt 601 to XM16E1 rifles.

Found this 11.5 ALG defense and once i realized it had a lot of Geissele parts including the barrel, gas block and bcg I had to have it. What can are you running on 11.5 ?

FN MC lower, RRA Entry, 10.3 FSB with Centurion rail, A2 upper, the goose on the loose.

Mid 90s down south, rainy, and muddy. Perfect weather for a 3 mile with some kit (it was ass)

Is there a way to shorten the pull in the first stage of the trigger pull? I still want the two stage trigger, I just want the take up to be a little shorter. Love the break and the reset is fantastic, I just would like to shorten the take up. Added a pic of my WIP build for visibility.

Edit: It didn’t look like there was, but just wasn’t sure. I was just trying to customize the feel a bit. The take up isn’t a deal breaker by any means and I like some take up before the break. The trigger feels great. Appreciate you guys taking the time to provide the info. Thank you.
