If you watch a few of these test flight video's, you can see one approach and landing where #4 is feathered,, likely an oil pressure or temp issue?

The Mars will be a great addition to the Pima Air Museum, I'm pretty disgusted the Convair XC-99 was cut up and taken to the boneyard rather than moved to Pima?? I had some great pictures of the XC-99 at Kelly Field, when my Dad had an adult stem cell transplant at Wilford Hall, around 1997, maybe Feb and March.. anyway, when we went to visit Mollie and Jacob, I drove by the boneyard,, and there she was, all hacked to bits, laying up by the fence.

I agree 98Z, Wilson Combat website is a mess these days, may try to give them a call... sorry for the delayed response, I see you're still hard at work here on 308AR

Since Gov Pritzker and the legislators middle of the night legislation in Jan 2023, Illinois has declared war on sporting rifles.. so who builds a crowned 6.5 barrel? I did build my last small frame with a Wilson Combat barrel with no threads in .223 Wylde... threaded barrels are verbotten!

Anyway, I really like the UBR Gen2 on my small frame 5.56 medium heavy barrel, it is a nice compromise between a carbine stock, and an A2 stock.. I had seriously considered an A2 for "Little Miss Wilson", but one of the real attributes of this rifle is to be able to put it in the carbine case and take it to the farm.. the UBR Gen 2 will be a big help balancing the large frame rifle,, and I really am impressed with the MOE+,, it has such a nice grippy feel to it.. so I'm really looking forward to upgrading the handling of this rifle with the Magpul furniture.

Sounds like fun,, I've been hankering for a Winchester Model 1897, some one had a replica riot gun on an original and it was very well done,,, don't ask me why... my Model 12 Featherweight keeps locking up on me when you rack the bolt all the way back, it locks up and will NOT return to battery,,, put it back in the gunsafe, lean it up against a tree,, and odds are if you grab the forgrip and pick it up, that sombiotch will slide right back into battery,, a couple of model 12 guru's camped out with it for 6 months,, couldn't find a single thing wrong with it, brought it home all dissapointed and sure as chit went back to intermittent but frequent locking out of battery.. OD Green Magpul UBR Gen2 with OD Green MOE+ for "little Miss Wilson",, yeah, she's spoiled,, but she is running the bomb with that full mass KAK BCG and Geiselle Automatics 2 stage Enhanced,, wow.. and my old Rock River with the nasty 2 stage National Match trigger, now runs like hot butter with a JP light spring kit,,, its damn close the Geiselle, I don't believe it either, and it may be my imagination,, but I put together a couple of decent 3 shot groups today with a cheap az chi com scope,, yeah, I know, I'm ashamed, but its glass...

So are we running now???

Oh come on Doc! give the devil his due!! fine shooting JB Matt, and 98! pay no attention to the man behind the curtain! shheesshh Doc??

Nice work gentlemen, and Kimmy!

I looks like a decent design Tyler, I do like the larger boss at the rear, but I will say the JP low mass that shipped new with my Wilson Combat Tactical Hunter had issues, broke an extractor, and was replaced by Wilson Combat with a KAK BCG.. I was seriously considering buying a Lantac 308 Enhanced for a spare, so let us know how you like it.

In the meantime, buy you a box of .308 ammo, and leave that Turkish 7.62 surplus for fun when you actually get your rifle running.. are you saying this top end runs well on your first build lower??? and that your first build upper runs fine on this lower??

Your DPMS style AR 308 does not have a firing pin return spring, nor do most DPMS rifles, and yes they will likely all dimple primers when you release the bolt.. but, it should not result in a slam fire..Who's bolt carrier group are you using??? is it clean and lubed, does the firing pin slide freely in the firing pin channel, back and forth without resistance.. clean it, and lube it, and only load two rounds in your magazine.. try some different ammo... if it still slam fires, pull your fire control group out of your lower, again only load on in the magazine, drop the bolt... I will add that this is NOT a common problem here on 308 AR. So your rifle has all Aero Precision components?? or did you mix and match.. we do like pretty pictures,, maybe show us the firing pin protrusion from the bolt face?? it could be to long?? who knows at this stage, but get back to us, and these gents will help you work through all these questions and get you some answers. The only manufacturer who does use a firing pin spring is ArmaLite,,, I take that back, Smith and Wesson puts them on their MP10, (more for CYA, but they had an MP10 that did slam fire due to a broken firing pin return spring, jamming in the firing pin in the forward position) its also possible you have a very light trigger?

Yep, mix and match probably won't,, no matter what anybody "tells" you,, unless you see it done here,, so build an Aero M5 and be very happy,, then pick up a matched Fulton set when you need a new challenge.. Wilson Combat flat out says that their upper and lower are NOT compatible with anyone else's... and no matter who's receiver set you build, you will likely have a few issues to get a working reliable rifle,,, I recently built a Wilson Combat small frame in .223 Wylde,, with a medium heavy barrel, (its to damn heavy), it is almost as heavy as my 308 Tactical Hunter, ran perfect right from the get go, until on round 16 it blew the ejector out of the ejection port along with the spent case.. so yeah, they can all have issues, and yes, I had enough parts this time to get it back into operation.

All good, so we are going to get a range report?? you know what I mean about the 3 1/2" and 4' barrels then,, just an amazing feel, I like my 4" 29-2 as well,, it loves those 210 grain Winchester Silvertips if you can find them.. I stay away from anything under 158 grains in 357, with the exception of Winchester Silvertips,, I think they are 145gr as I recall in the 357.. Federal 125's and the like, do seem to cause a lot of flame cutting of the top strap and throat erosion,,, on the model 19 and 66 they've caused a few cracked forcing cones.. they are hot, and all that powder is wanting to go somewhere and do something amazing in a hurry.. the 158's are just easier on your gun.. I also avoid a lot of fast double action, as that cylinder is big and very heavy,, it could cause you timing issues down the road.

How's it going new guy?? we do usually ask new gents to post a little about themselves and their objectives in the introduction thread... once you do that, we will be better able to help you. I'm assuming the pink small frame for the Missus?? (wink, wink, yeah I like pink too, all my arrows are typically built with a cobalt blue X7 Easton shaft, white nocks, and pink and white feathers, I love to watch my arrows fly, pink and white show up very well), but I digress.. so I'm assuming you are building a 5.56 rifle??? I would recommend building the small frame first, there is a mil spec for the small frame rifle, and most parts will fit most rifles... and then move on to your large frame rifles, no mil spec on the large frame, (as you've already found out, Aero has proprietary pivot and take down pins..) so are you planning to build a .308 and a 6.5 Creed?? I would build the .308 next, it should be easier to get running than the Creed?? as 98Z5V states, read, read, read, and watch a few you tube videos, perhaps someone will post a link to a good one?? have fun, it will be frustrating at first, but it will get easier.. if you start with the small frame rifle, the information is much easier to come by, and there are less proprietary parts, as 98 has also recommended, ask before you buy more parts..
