GRA

Very creative indeed. <thumbsup>

I'm hoping this pulls Colt out of whatever crunch I've heard they are currently in. I like their products even if they are pricey. They're an American icon and I hope they stick around. If this risk turns out to be positive. American manufacturers need as much business and support as they can get.

Has DOD ever given a reason why they won't approve a changeover to the caliber for our forces?

Glad to hear this is turning out as needed. Anxious to see the specs on the new BCG when it arrives.

I'm in when it starts. Thanks

Is this group buy closed?

You're 100% right. How else do you think Pelosi got her ideas ... ???

I'm still getting off work too late to get over to that shop in time. Maybe I'll be able to get there Friday.

Which model of trigger did you buy? Trigger pull weight?

Now that I think about it, I wonder what springs from whatever mag I can place in the 28 round mags to see if I can get 30+ ?

Smooth move by Colt. They might've found a marketing niche' with this one. Might be what finally gets their finances back in order. I'm sure countries in the Middle East will at least take a good look at it. Obviously they gave up on somebody coming up with a decent mag that works so they designed around it.

Thanks. Not cheap though are they? I'm sure I have far less in the mutt model I built. :))

Does anyone know if Colt offers an AR in 7.62x39 anymore? I've never seen one in person but was told they are out there.

Welcome from Texas !!!

And the Anointed One is on record more than once stating the USA should be restricted to Australian-style gun control.

Rough weekend carried over today in to what turned out to be a rough day. Hopefully I'll have time to get by there tomorrow and enough time once I get there to take measurements. My job location and the vendor are at opposite ends of Houston which is murder in late afternoon traffic. I'll try the spreadsheet program on this new Apple comp. and print one up before I go so I can organize the measurements. Thanks Bob for the .pdf as it will help out.

I'd go in on a group buy for a pencil barrel 16" mid-length 4150 QPQ with a 1/7" or 1/8" twist. Sounds like a great build !

I am going to the vendor's shop this week to get my buffer spring and this should complete my parts. All I'll need is simple assembly thereafter. I got the impression from them that they have more brands of BCG(s) there than they brought to the gun show. I will bring my calipers again and will be happy to measure whatever they may have then post it on here. I probably will not be able to do photos. From what I can tell at this point, it is obvious there is some difference between our AIM BCG(s) and the JP low-mass BCG I measured today. I'm sure the same goes for others. I am not an engineer so if you want me to take measurements other than what I have taken above please let me know.

That's good. Hope it continues in the other states regardless of it occurring on a holiday weekend or not. I don't know why August 29th. was selected here but the vendor I spoke with said to call her back at the end of the week as she will be calling the Comptroller's Office. What was interesting is she pointed out how they have a layaway program for items in their current inventory. You can simply drop a downpayment and nail down the prices then right on the magical weekend go to the gun show and pay the balance and still avoid the taxes. The sale of course doesn't occur until you take possession of the item and that can be done at the gun show. Gun show venue will most likely be packed that weekend.

For those of you that may not have heard ... According to a vendor I spoke with today at the gun show, the weekend of August 29, 2015 will be a tax-free weekend for guns and ammo purchases. I was informed this will be a weekend tax-free session, not simply a tax-free day. They were unsure if this also applied to internet sales. Just thought I'd pass this along as it is indeed great news. <thumbsup>

Great news. Thanks for the update. Makes me wish all the more I could simply get to the range. <thumbsup>

Bob ... I made it to the gun show today. Place was full. Out of everything being sold there I only found 2 JP BCG(s), 1 DPMS .308 buffer and no other buffer parts. I only counted 6 finished rifles there, 1 Armalite DEF10 and the rest were RRA and DPMS .308(s). Nothing else except ammo and plenty of AR15(s) and AR15 parts. One vendor that has actually received some Spike's .308 lowers in actually pulled them from their display because the were absolutely bare and still cannot get the Spike's lower parts kits in and other related parts. Either the .308 is not yet that popular here, or they are extremely popular and nobody can keep parts on the shelf. I took measurements from the JP low-friction BCG with my digital calipers. I hope I hit the same areas you measured previously: Under the gas key: 1.0680 diameter (this is right under the tip of the gas key where it slides over the gas tube, top to bottom) Bolt carrier area / front of carrier (where the bolt enters): 0.9470" Ramp length: 3.2510" All measurements were in inches. I don't know if this did any good, but that's what I got. They were selling nickel-boron bolts in these teflon-coated bolt carriers for $459.00 each.

Welcome to the forum. Congrats on our exceptional purchase. Enjoy sighting it in. <thumbsup>

I've most likely had this misunderstood. I guess the high vs low is the measurement from the very top of the rail down to the bottom of the channel for the charging handle. Good point made about the design of the BCG and the new Geissele. I'll keep that in mind. I've never used a Geissele but can't say I won't in the future. I never made it to the gunshot today to check out some BCG(s) and take measurements. Hopefully I'll make it there tomorrow (Sunday).

This is indeed great news. Elated that this finally got up and running. You put in a lot of effort and it definitely paid off, even without FedEx's assistance ... LOL <thumbsup> <thumbsup> Thanks for the information on the scopes. They seem to be quite popular but I've never fired with one. I'm wondering now about the Geissele trigger group that set you back. Do you think the particular trigger you bought might've been for the "DPMS high", and that is the reason it did not work (referencing your previous post regarding high vs low) ... ??? Let us know how the MechDef trigger performs. I've still got a week to 10 days on my build at minimum.
