I just looked, and the KVP 7.5oz buffer is 4.125”. No way it would work in .223. I guess the 9mm doesn’t have to go back very far to lock on a colt/Glock mag.

Kowa scopes are awesome if you can justify the cost. I used my 82mm for highpower for years. Most days .223 hits at 300yds were visible, depending on the lighting.

What weight were you using? I have one of the solid 7.5oz KVPs I might try.

Shooting in the woods on my home range I prefer green (vortex spitfire). In matches with dirt berms and direct sun I prefer the red.

Very cool, thanks. I’m going to check that out tonight.

Mine do, 100% of the time. I’m using a mag block with my SBR lower. Otherwise it runs great.

Im also a fan of the K2 on my PCC. It is a little grippier than my BCM mod 0 which I also like. Basically any of the more vertical grips I like nowadays. But there is no "best".

I would agree that the squarish corner profile is a little harder to get when you are chicken-pecking with Dillon tubes, but I've never had an issue when seating them. I've shot about 3-4K of them in Glocks and PCC, all went bang. Local Cabelas has them occasionally.

Adjustable gas system is eye opening. Once you have that, you'll have a baseline amount of gas that it takes for your rifle to cycle. As you lighten/upgrade parts in the reciprocating system, you'll notice that you can close your gas system a little more. This generally amounts to less sight movement too. You can even see things like worn gas rings. Changing to fresh ones for me allowed me to close my gas block another click or two.

I also use intermediate magnification a lot. Somewhere around 2.5X is good for finding mini-poppers in grass at 75-100 yards.

I would be fine not having 1x only if I had a really good set of fast offset irons. I am definitely slower with magnification >1X in bay style stages. If there aren't any targets under 50 yards, then not an issue. I can't see a situation in most 3G events where you'd need more than 6x though.

At 12.99, I don't care if there is a little surface rust. I haven't experienced that in mine, in AL where it can be pretty humid.

Colt style mags are a beast to load. I've been meaning to get a lula, but for now I find it easiest to stand the mag on a table and force rounds in with both thumbs. Definitely limits your ammo consumption. Good luck.

May be from using pistol length gas system on 300 blk? 100% of my 300 blk is suppressed, which makes a mess, so I couldn't compare apples to apples.

Some brakes are worse than others. I was shooting the AAC 51 tooth mount/brake in 3 gun since it worked with my can. Doubling up on ear pro worked fine for my ears, but the overpressure would often blurr my vision, I guess because it was messing with my retinas. I switched to a Lantac dragon for 3 gun and it is much better for the shooter. Shooting a brake, plugs under muffs seems mandatory. My ears will ring if the plugs aren't in. Electronic muffs on top of plugs are great, you can crank up the volume to a comfortable level to where you can hear conversation and range commands, and you're still double protected.

I've noticed that my PSA/metalforms will pop out several rounds if dropped on the ground. Maybe the spring tension is high enough for two to slip out when your bolt slams back? I would try leaving your mags fully loaded for a couple days before trying again.

The PSA metalforms are all I run. In my PCC I am running 147s short (1.09) and haven't had any issues with them. I have 10 of these mags but I'm only really using 4 of them.

Spinta bolt Anderson lower -SBR'ed Ballistic advantage 5.5" barrel Milspec LPK Lower conversion block - KAK MFT stock Magpul K2 grip Aero upper Aero quantum 12" handguard, tucked Octane 45 can KVP 7.5 oz buffer 308 buffer spring Vortex Spitfire Been 100% with for hundreds of rounds with the crappy milspec trigger, not so with other triggers. Still working on that.

How do they compare to the ETS group 140mm mags? Any reason to by magpul over them?

I run a KAK mag block and it has been 100% with metalform mags. Only reason I choose to us the block is because I already had an SBR lower. I really like the stick mags and they're cheap, 12.99 from PSA.

I'm considering trying their Glock barrels. I am impressed with the PCC parts I have bought from them- barrel and bcg are great.

My SD3G is very difficult to not bump fire in my PCC. About every other mag you'll get a dead trigger too. A lot of fun, but not appropriate for competition.

Agree, you should add the MTAC.

Oops haha then no excuse for the OP not to buy them. Sorry wasn't tracking the 170mm.

The magpul ones aren't metal lined, so I don't think a magnet will be of much use there. I have a few and they are ok, but like others have said there aren't enough witness holes to see how many rounds remaining. I prefer the ETS mags. In your case, i would just use factory Glock mags plus extensions. The real benefit to the ETS mags is that you can have a 140mm mag for less than 20 bucks. Since you'll want to add an extension to get to 170mm, might as well use more durable OEM mags to start with for only a little more $$.
