I don't, but couldn't hurt. I have a vortex 30mm cantilever un mounted, may just try the honing bar in it for fun. I would always mark the caps if they come assembled.

Thanks What would be a good price for the M5?

I was talking to the seemingly knowledgeable guy behind the counter when I was getting the Aero Gen 2 X15 lower and he said the Aero M5 I was also looking at was non spec (non DPMS Spec.) Said he tried to mate it up with a M&P 308 Upper and no bueno. normally I would have started arguing with him whether I knew what I was talking about or not, but it's Friday, cold beer at home, so I took my purchase and left. So is the Aero M5 non DPMS or is the Smith non DPMS?

woohoo!

Guy I work with is itching for a build, I told him you can't go wrong with Aero. I stopped by Outdoor Emporium about 4 blocks from the office on the way home and Aero Gen 2 $72.00, sent him a text, then went back in and bought the last one. (I justified it knowing they will have more in next week...) Snooze you loose...

Thanks for the vote of confidence! I like to see SD's less then 10 for rifle, but if you play with a dope sheet with magnum rifle velocities it takes a lot more then that before you could even measure the difference at 500 yards. Revolvers are the worse offenders, forcing cone gap blowing pressure off, un-even cylinders, if I get an SD in the under 30 range with a magnum revolver load that's an accomplishment.

Working up some new Barnes TTSX loads for the 300 Weatherby Lubed, sized, trimmed, chamfered, uniformed the flash hole sorted by headstamp loaded up a ladder and went to the range. 1st group varied over 50fps, second group not good either, 3rd or 4th group max sammi had 1st 3 within 5fps spread and last 2 almost 100fps slower. Same with the max + .5gr batch, WTFO? Luckily last 2 batches were 3 good ones in a row and 2 slow, got me thinking... Looking at the brass when I got home I had mixed Weatherby R-P 300 Mag and Weatherby 300 Mag brass. Case volume 6.41 cc h20 vs 6.67cc h20, dry weight almost 15 grains more with the R-P. Looking back at my data it looks like R-P with 79 gr H4350 was close to the same velocity as Weatherby with 80.5, assuming all the slow ones were the Wheatherby I checked dry weight on a few Normas, and a couple other brands I had 1 or 2 of, all close to the R-P. Weatherby brass has more volume then the rest. Got to sharpen the eyesight at the reloading bench before sending 25 bucks worth of reloading components down range at 3400fps!

AR Pistols are my goto when the zombies attack!

5d on sale 10% off

Yep. Carbon copy different color.

Modulus Arms is the other one. With the 5D it's easy to end up with extra parts, if you get the milling kit you don't need the mill. The 308 extender part costs the same whether you bundle it or buy it later if I remember correctly. It does ar9/ar15 with the basic pro kit.

There is another brand as well that appears to be a clone of the 5D, shows up about page 3 of a google search. I think I went with the 5D rather then the 80 because of the cutter and router base, but to be honest I can't remember exactly why I chose it. I did look at both pretty extensively before making a choice, close call. The 5D I have does do 9/15/308, good chip extraction, and is very beefy. I also went with the recommended router, and a foot switch is a great addition as well. Zero issues.

What Jig are you using? The latest 5D Pro worked quite well for me on a AR15 lower, have the 308 parts for it also but haven't done one yet.

If you want to bring a build in under $1,000.00 that won't let you down when the zombies attack, Sightmark is on the list.

The Spec series uses the big battery. Lasts forever. The detachable mount returns to zero very well, even though I don't think it is an advertised feature. We put one on a friend's AR 40 pistol and it required absolutely zero adjustment, right out of the box. I adjusted mine once when I installed it and never have had to touch the adjustment since. Little over $100? I'm impressed.

Think I see a Sightmark on that DB Have nothing but good things to say about my R-Spec.

Tried out a Stern Defense Drop in FCG for blowbacks in the carbine, definitely not the feel of the SR Gold I have in the 308 but not bad for $139. 2lb+2lb 2 stage in its stock configuration. Comes with an extra green spring for a lighter "Not recommended for blowback bolts" setup, might try it in one of the DI guns, maybe it bridges the gap between $300 dollar "Breaks like glass" FCG's and Millspec single stage "creep, creep, bang"

Back from the range, final results in: 16" Carbine Sprinco red spring / 10 oz KVP tungsten buffer chewed through 180 gr plinkers, 180 gr major loads, and 155 gr 1500 fps+ with ease. Good "back on target" split times. 4.5" pistol Ditto above except for didn't run any of the lawman 155's From several trips to the range with various combinations, it seems to me a 10 oz buffer will run with several different spring weights, both pistol/ carbine, but a 7.5 oz buffer will only run in the pistol even with the EA1095 spring Slower cycling makes cheap mags work better, and factory mags work flawlessly. Springs I used from light to heavy KVP Extra Power 308 carbine Sprinco Red EA1095 Buffers: KVP 7.5 and 10 oz Just my opinion, but it seems possible to over buffer to the point that rounds will feed but bolt travel is insufficient to engage the disconnector, resulting in burst mode Also my opinion, it seems possible to under buffer to the point that the bolt speed is fast enough that either a. parts are moving so fast that the disconnector doesn't grab, or b. the effect of slamming into the "end of travel" jars the disconnector enough that it does not grab. Whatever the mechanics involved the results can be a bit bloody, out of battery slam fires and such, highly recommended to avoid at all costs!

Is that a commercial vs Milspec thing?

There goes the spending moratorium

My 458 ain't bad to shoot, buttstock makes all the difference Adaptive Tactical

In the middle of liberal-ville, Bellevue WA, you will find Lowpriceguns.com Little shop Quick service Lots of AR lowers very knowledgeable about the legal stuff, pistol builds, braces vs stocks, etc. Never been over 10 min for FFL stuff. I live in Seattle but nothing here, as bad as SF.

Envious is all I can say

Just read through your thread, 2 things jump out. Headspace and timing As you tried 2 different barrels, could it be the bolt causing the headspace issue? I'm relatively new to AR Platforms but been reloading since before the Clinton Administration and stuck cases and headspace issues transcend platforms I would be curious to try one of the spent rounds in a case gauge. May need to cut the neck off or neck only resize the brass to get it to fit. if the bolt starts moving back without the resistance of the shell, possibly could pick up enough speed to bend the bolt catch on the way back . Did you ever replace the extractor, or just the spring?

+1 on slower bolt speed making the cheapie mags feed better, even the uber cheap ones. Red spring maybe even better judging from last sundays data, although I didn't have an orange spring to try.
