Actually, according to the MSM, he bought the .45 himself. His father apparently did not buy it for him.

OK, I put 20 rounds downrange without any failures and the BCG locking back when the magazine was empty. Like an idiot I forgot to put the bipod in my bag so all 20 rounds were shot offhand. I was able to put all 20 in an 8" circle at 100 yards, with about half shot as double and triple taps. The Miculek brake does a really good job of keeping the barrel level and there is no more recoil than my AR-15, which has virtually no recoil. This was actually a double test since the ammo I was using were my first hand loads. In this case they were Rocky Mountain Reloading 147 grain HPBT projectiles over 44.1 gn of Varget and using Winchester large rifle primers in once shot cases that I prepared. Interestingly they proved to be very accurate given the circumstances. I really think the Faxon barrel (18", 10:1, 4150 moly QPQ) is outstanding. I really can't say enough good things about the barrel. After that I put 30 .223 rounds and about a dozen 30.06 rounds downrange to check the zero hold on their glass, which maintained zero very well. <thumbsup> I need to think about what the next build might be; however, I want to take some time to get more deeply into reloading, moving into 9MM, 45 ACP, .223 and 30.06 for the rest of the family as well as the .308. :banana:

Obviously he doesn't consider France, Norway or Czechoslovakia as major countries - Oh, I forgot, we can't criticize this affirmative action Administration or we are racist. I really think it was inappropriate, close to being obscene, to rail on gun control then go to a fund raiser and play golf within a couple of hours of the event. Prayers for those who were killed and their families. The problem? To me a large part of it is mainstreaming those who should be institutionalized. Another liberal mistake.

It does touch, just slightly, enough to cock the FCG when charging. I was comparing it to the original where the hammer of the Geissele was binding at the shoulder of the BCG and wasn't quite accurate in the description. Thanks to all for the advice as it really helped as I worked through the issue. I suppose the bright side was switching the Geissele to the little brother (which needed it) and encouraged me to get the MechArmor drop if for the big brother. With my lack of control with the left hand that no travel light touch trigger really should help.

You did. AIM swapped out the original for a new one which will be going to the range in about an hour (only 94 now). This one is even a little shallower than your Fulton Armory BCG. AIM does just sell, apparently the manufacturer produces these for quite a number of suppliers. It is very smooth, no machining marks, and feels almost wet.

I'm not sure how to make a suggestion since my upper and lower fit perfectly; however, they are both Spikes Tactical. I really have the impression that if you want a good fit, keep the upper and lower the same brand. Come on over 98, it will only be 101 to 102 at the range here tomorrow afternoon (and we have a great sun shade).

OK, the replacement BCG has arrived. The measurements are quite different compared to the first one. The carrier depth just ahead of the gas key is 0.930" compared to the 0.950" that the first measured. The distance from the front of the carrier to the shoulder is 2.190" compared to the 2.250" of the first one. The BCG drops into battery when inserted with the barrel oriented vertically. The depth of the carrier plus the gas key between the screws is 1.191" indicating that the depth of the flat portion of the gas key is just about the same as the first and all the others that I have measured. It appears that the hammer for the MechArmor FCG actually clears the carrier without requiring either the carrier to ride over the hammer or the hammer to depress slightly to allow the carrier to pass. Charging appears very easy and smooth. I have headspaced the BCG and it is now residing in a synthetic oil bath until I can get to the range tomorrow. Thanks again to AIM Surplus for doing the right thing and both of the BCGs they sent were completely void of any machine marks and were extremely smooth and felt very slick before going into the oil bath.

OK, the swap out BCG should be here tomorrow so I will try to get to the range on Friday (use some of the 26 hours of comp time I will lose this month) to see how it operates as well as fire test the MechArmor trigger. I will do some measuring while headspacing the new bolt to ensure I have a significantly shallower carrier. The ones they had on hand measured roughly the same as 98's Fulton Armory carrier in depth as well as one or two others whose measurements I have seen on other boards.

Sorry, I didn't mention that after depriming and sizing the previous week I trimmed all of the cases. I do appreciate the suggestion based on my omission. I also use a headspace die to check each case before priming.

Well, after catching the build bug the reloading bug has also struck. Over the last few months I have been acquiring reloading supplies. Last week I deprimed a hundred once fired .308 cartridges, swaged the military brass, and cleaned them up in the Frankford Armory tumbler with the ss pins. Today I used the Lee hand primer and the Lee Classic Turret press to load those cartridges. Perhaps because of my concern to get the loads correct I hand measured all of the loads individually, which was the slowest part of the process. I have a Lee single press, the turret and a Load Master but I think I will save the Load Master for handgun loads (I have .380, 9MM Luger, 38 Special, and 45 ACP). I need to play with the Lee Classic Power measure to feel more comfortable that it will dispense adequate loads. I do need a trickler to make measuring the loads a bit less time consuming. The 100 were for plinking (147 grain FMJ over 44.0 gn of Varget). The next exercise will be building some accuracy ladders for the 175 gn FMBTs with Varget so I will be ready when the replacement BCG arrives from AIM. I do feel like I accomplished something!! <thumbsup>

Well, Mexico is 4 miles from the house and New Mexico is a mile and a half, but we are in Texas!

So many choices and opinions. I just went with the Miculek. Between this brake and Slash's buffer, my .308AR has less kick than my AR-15 which has no brake.

Thank you for your service, and since you are studying engineering you can be excused as referring to Lubbock as West Texas. Welcome from the real West Texas on the border.

Abbott signed both open and campus carry today.

I got mine in between the group buys, but still a great price at $135. Van called today to see if I was pleased = outstanding customer service! The trigger has a very light pull and there is NO extra travel. <thumbsup>

I do have the measurements that the AIM staff gave me, depths of the carrier in front of the gas key ranging from 0.930" to 0.9335" compared to the 0.950" on the one I had. Those measurements are in the same ballpark as 98's Fulton Armory BCG. I just had a call from Van from MechArmor about the trigger I purchased and I can't wait to get the replacement BCG so I can get it out to the range. It is a very nice trigger and should really help with having to work the trigger with my left hand.

Then neither of these communists could commit suicide with any old gun. They would have to buy one or jump off a bridge!

Welcome from the border to someone from my home state - Pittsburgh native here.

My Spikes Tactical .308 also has the takedown pin detent and spring as well as the safety detent and spring held down by the grip. I thought this was fairly common for DPMS pattern units.

After long discussions with AIM and comparisons with the depth of their BCG units that they have on hand, we have agreed that the best thing to do is for me to ship mine back and they will swap it out for a new one. While the MechArmor drop in clears, the 0.015" to 0.020" difference in depth from what they were measuring on in stock units is just too much for comfort and probably why the unit is so tight when putting it in or taking it out of the upper. It certainly looks as if AIM will do the right thing and certainly stay on my list of favorite suppliers. <thumbsup>

They only sell one trigger - 3 lb. pull with no extra travel - very nice.

OK, an update. Today, quite unexpectedly, my MechArmor trigger arrived. I installed it and.........the rifle cocks perfectly with no hint of binding. Apparently it is just the Geissele setup and the stiffness of the hammer that is the problem. By the way, what a sweet trigger. Very light pull and very clean break. I can't wait to get this out on the range.

OK, I think it was 2.019" front to shoulder so that leaves 1.231" shoulder to firing pin well, 0.936" depth forward of gas key and 1.190" depth over gas key base. The Fulton is in the spreadsheet.

98, assuming front to firing pin well is 3.25"on yours I will put Fulton into the spreadsheet.

Welcome from the border!
