I've never, ever had an issue with the AP mag catch, in AP M5 receivers. Ever. I'm up to about 5 of them now. Never an issue. Specific pictures of the issue you're having would be beneficial to this discussion.

You're already at the correct forum. We'll figure it out - and it doesn't seem too hard, based on your info. Get into more details on it. Welcome aboard.

The Ballistic Advantage Grendel barrels are incredibly accurate. I can testify 3 times on that fact.

Msg sent, brother.

That's a badass light, right there. When you try it out an come up with info, dump it in this thread here - I made this one just for Olight information:

Damn, if that ain't the truth...

That's some bragging rights, right there, to the Club Chicks. They don't know shiit about metric, but it sounds good to them!...

Make it the baddest 14" CockFantasy that you possibly can, brother - make it a legend...

You underestimate the man that you are, brother, and how much others could learn from you... You are a humble man, and that is commendable - but you are a Giant amongst men...

Big praise for Mike @Magwa - both for what he's done here (SO many times before), and the large leap of faith and commitment he made over at Full30.

Just watch this - you got it...

He got a new shotgun to play with today - he has a massive boner...

Operation Just Cause, Invasion of Panama. 19 December 1989...

This thread went sideways, by the way... We pulled it off!...

AR15, brother. Small-frame AR. It is a bad bastard, over the 5.56 round. Barrel change only. Same mags, same bolt/BCG. It's just a barrel change... You neck the 5.56 cases up to .25 caliber, and you're done. It's easier than converting to .300BLK.

Fucking EPIC, brother... That's exactly how I feel about PSA PA-10s... You can MAKE them work, with WORK. It's the lowest level of "probably operational for most people with most Wal-Mart ammo most of the time"... but it's far from a functional gun, as you receive it. That's why they're as cheap as they are. The only thing you could do worse is buy something from Davidson Defense, or any other name that that POS company operates under. The PSA PA-10 won't categorically destroy your life, like CMMG parts will do, but it'll leave you pissed off until you get it right, and make it run - by making your own modifications to it that WILL make it run right. PSA certainly won't do it for you, with that "Lifetime Guarantee." P.S. An adjustable gas block is NOT your answer to a PSA PA-10, to calm it's "over-gassing." It's not even possibly over-gassed, when it ships with a gas port diameter in it's barrels that is UNDER-SIZED... That's Unpossible... That's a hint...

Not with the spread that you have, brother - that's a small piece of heaven, right there. You own a gorgeous piece of the planet...

Exactly. Bolt, barrel and mags. Nothing more. Everything else is small-frame AR. The best mags out there are E-Lander mags. Honorable mention (and damn good mags) are ASC Grendel mags. For the BCG (and bolt), nothing other than ToolCraft.

My biggest accomplishment for the 25-45 will be to put the time in on my 100gr Barnes TSX-BT projectiles, and get that load squared away. I played with them, but I need to do alot more work with them. Once I solve that one, those 90 SGKs will be a thing of the past. Those Barnes 100gr TSXs will be the SHIIT...

I took that 25-45 out to 850 yards, but it was a challenge with the scope I had on it. PA 4-14 mil-dot scope, with a straight mount (Aero Precision) and no MOA built into that mount. With that straight-up scope mounting, I had about 10 mils of drop travel in the scope, in it's internal adjustment ability. Those shots on the 850 target required 17.5 mils of drop, for my 90gr Sierra Game King handloads - and they're moving, too. It was all experimentation, beyond those 10 mils of scope travel... It was holding mils in the reticle, until I got it there. It sucked to figure it all out, but once it was on - it was on. If I run a 10 MOA mount, that'll give be back about 3 mils of adjustment in the scope. 20 MOA mount will about get me there, with close to 7 more mils of drop in the scope. 20 MOA mount will just about get me where I need to be, just with dialing the elevation turret, at 850 yards. If I shift the thing to a 200-yard zero instead of a 100-yard zero, the 20 MOA mount will definitely get me on target at 850, dialing-only. That 25-45 is a beast out to 500 yards, on that 90 SGK load. That's all I ever wanted from it, in the beginning - split a coyote at 500 yards. After that range test on it, I want it to do better out there at more distance, though... That's gonna come down to scope mounts and zero distance...

For what it's worth, and all the Valk-Hype out there about it being some wonder-gun that's supersonic to 1300 yards... It's not. Hornady Black 88gr Match ammo, straight from the factory, is supersonic to 1100 yards, from an 18" barrel. You'll need a LOOONG barrel to keep that thing supersonic to 1300 yards... 12.5" Grendel with 123 handloads is supersonic to 900 yards. 16" Mk12 Mod H Grendel with that same load is supersonic to 950 yards. 18" SPR Grendel - same load again - is supersonic to 1000 yards. I'll take the Grendel, and the 35gr-heavier projectile... I don't know what load that the Valk-Crowd is hyping/claiming to be supersonic to 1300 yards, but it's not a 75gr Hornady or 77gr Sierra projo. It's not the 88gr Hornady projo. It's not the 90gr Sierra MatchKing, either. If it's the 95gr Sierra MatchKing - that thing needs a 1:6.5" twist barrel to stabilize it. The common 1:7" twist Valk barrels that are out there in the wild won't stabilize that projectile... My $0.02 on it all...

The most perfect, efficient cartridge ever developed for the small-frame AR, ever. And, I can compare that to the .224 Valkyrie, as well - only one of those, and there will only be one. This is truth. I have 5 myself - they BREED! Built a very sweet, very special one for @Matt.Cross, too. I built a Vakyrie to test "the hype" that's out there about how it outperforms the Grendel in every way... That's not true, when you look at it closely. The Valk with 88gr Hornady ELD-M Match ammo does indeed have a couple clicks less drop at 850 yards, and it is accurate as all hell - just like the Grendel running 123gr Hornady ELD-Ms is. The big difference for me is that the ballistics are almost identical, I'm delivering a 123gr Grendel round on target with a little (insignificant) more drop - and that's 35 grains more projectile-mass over that 88gr round. Both are Hornady ELD-M Match projectiles. I'll take the Grendel, every time. Built the first 18" Grendel, and it was SPR-ish, Mk12 as I could get it as far as important parts. Not a Mk12, but "SPR" instead. Stellar performance at 850 yards. Decided to build a short one, so I did a 12.5" Grendel. When it accurately, repeatably, went 850 yards with a 4x Leupold scope... every time... I was sold, for good, on that cartridge. Then, they started breeding...

Yeah, you're gonna need to bust that bitch down, brother. To the guts. It's a simple process, once you do it. 500 and 590 are identical in breakdown.

Not at all. Put a live round in the barrel/chamber by hand, but it's gonna fully seat - the chamber will be perfect. Lightly run a round in there with the BCG and finger pressure (upper only) and seat the extractor over the rim on the round. Should you check headspace on a .308AR? Always. I just described a way to do it.

Olight. If you guys haven't been checking them out, then you should. Olight is gonna give the big-money companies a monstrous run for their money. I started dabbling in this stuff over the summer. Sign up for their notifications. It's well worth it. https://www.olightstore.com/ I can tell you right now that this 1500 lumen weapons light is BADASS... https://www.olightstore.com/bundle-pl-pro-1-rpl-7.html The Mini Valkyrie is also BADASS!!! https://www.olightstore.com/pl-mini-2.html I'll get reviews and writeups coming on these. Already have them. Just need to get them out on a night shoot, get pics, etc. Olight is slaying big-name companies, with the quality and prices. They rock, men. Hard core, too.
