300 BLK rifle upgrade thread

[SQLGeek]

Charlie is asking about buffer tubes (receiver extensions), not gas tube lengths.

But all of the above is correct per my research as well.

I'm really leaning toward a 9" 300 blackout pistol. If I had a can already I would have done it already.

The grey is sharp. The grey Radian and SB3 brace are both on my build list.

 

[Charlie]

I think my barrel is either 8.5" or 9" but it's spoken for in a trade at the meet. If you're going to the meet be sure and check with me.

He did say he wasn't an expert...

 

[Charlie]

Glad to hear that! Very few people I've met who claim to be experts ............... is in their own mind!

If I can swing it, I want to have all of my parts together for the build party we've been talking about. That and I'm looking at dropping the coin on a BCM 9" barrel.

Well see what happens!

Keep an eye out for PSA FN barrels. Mine 300BLK is SBR’d and has a PSA FN barrel. Considering it’s not designed to be a long range tack driver I figured that was about the best way to go.

They have several different ones in stock. The FN barreled ones say “CHF” in the description.

 

[SQLGeek]

I've heard good things about their CHF, will check that as well.

It's kind of dumb but I have an 8" handguard I want to build around so 8.5 to 9" seems to be a solid barrel length.

My 7.5” barreled PSA upper had a 7.5” handguard...the muzzle device was the only thing protruding.

I had to put a shorter handguard on to clear a can.

So consider clearance if you ever think you’ll get a can...but I think your plan works just fine for one

 

[SQLGeek]

Already thinking that way which is why I'm fixated on a 9" barrel. That gives me an inch of clearance with the handguard.

 

[zackmars]

People laugh at the price, but the Geissele ACH and SCH are amazing. It's mind boggling how smooth it can make your gun.

The AXTS/Radians are nice, but outside of clones, Geissele is my go to. Unfortunately i don't think they have them in grey.

You cam often find them on sale for $50 or so

 

[mamboloco]

if you plan to shoot suppressed use an adjustable gas block.

Did a few upgrades today.
Swapped this rubber grip from another rifle to replace the hard plastic one.

Rubber grip donor, which also got an Elftmann trigger upgrade and a more-vertical grip. It’s an MC5 with MC6 internals which includes an upgraded trigger, but I wanted a Gucci trigger in my favorite rifle. This one is 5.56 but it’s my thread and I can post what I want
Original grip:

Upgraded vertical grip and trigger:

Installed this LMT 2-stage trigger on my 16” rifle from the first post...these guys spare no expense in the packaging department LOL...surprisingly Modern Outfitters uses Mil-Spec in the MC5:

And installed a BCM PNT trigger on my Aero/PSA 300 BLK pistol poverty pony, along with a more-vertical grip. Huge improvement over the PSA Mil-Spec:

If you haven’t tried one, I HIGHLY recommend the B5 grip. Much more vertical, personally the most comfortable carbine/fighting rifle grip out there. Precision rifles get a different one but everything else, B5.

Good looking tools!

Thanks!

These are Magpul MOE-K2+, I’ll look into the B5...some quick google-fu didn’t reveal much in the way of comparison tho.

I have the Magpul on my 5.56, but I put an Ergo grip on my 300BLK. The only reason I didn't change out the 5.56, is that at the time, I couldn't find an ergo grip in ODG.

 

[pronstar]

I’ll check out aero as well.

I was sorta comparison shopping, then these magpies were on sale for like $14 so that pushed me to give ‘em a try

The Magpul is definitely better than the standard grip, the ergo just feels better in the hand.

How's the B5 compare to the BCM grips? I just picked up a BCM Mod 3 and really like it.

Yes sir, definitely agree with that! And your hand doesn't slide around when it's sweaty.
