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.

jbran - check out my SBR bolt picture in this thread: http://forums.brianenos.com/topic/252550-colt-9mm-magazine-feed-question/?tab=comments#comment-2810470
With your mag inserted in tripod mode, is your ejector aligned correctly with the bolt ejector channel? If it's getting jammed up against the top of the channel, you need to lower & tighten the mag block. They do creep upwards if not kept tight.
Very cool, thanks. I’m going to check that out tonight.

Just curious do all Colt lowers/mag blocks jam up the bolt if you use the mag as a tripod while shooting?
Mine do, 100% of the time. I’m using a mag block with my SBR lower. Otherwise it runs great.

For the PCC, I prefer the Magpul K2.
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".

Some say they're harder to seat than CCI. I haven't found that to be the case with SPP. I do have that issue with their LPP. My only complaint with the SPP is that the bottom of the cup seems to be less rounded than CCI, so they're a little harder to pick up in Dillon primer tubes and more easily flipped. But they've worked fine in my Glock's and K-frames. And the price is usually hard to beat.
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.

Was a rather facetious reply. Actually, most people probably use 1X most of the time. And a lot of people just go from 1X to whatever max is without using any of the intermediate levels.
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.

The biggest advantage of the Brownells mag vs the cheaper blued metalform is the coating
i tend to get lazy when I put my stuff away, the Brownells mags are fine, but the metalforms will have a coat of surface rust on them the next time I use them
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.

I am waiting for my Maglula to arrive and will then top off all of the mags for break-in.The intermittent nature of the problem is what I am trying to solve.
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.

I use 0-20 Synthetic on the bolt and carrier and wet it down.
Works for me.
But - on the 300BLK I've noticed it carbons up around the tail of the bolt much more quickly than on the 223 or Grendel.
Oil, or just the nature of the 300 BLK?
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 SpitfireBeen 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.

The SD-3G is hit and miss from what I have read. The geissele triggers are not designed to work with a ramped bolt.
I would look at the tried and true choices - Hiperfire (24G, 24C, and eclipse) or JP. Both work well with PCCs and do not have issues with a ramped bolt.
If you have time to wait and really like Geissele triggers, I believe is coming out with a PCC specific trigger.
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.

Dang, no love for the old 1-4 mtac??
Agree, you should add the MTAC.

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

Been thinking about grabbing some additional mags for my open Glock. Wondering if the magpul one will magnetize on my belt? Also, thoughts on the ETS mags?
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 $$.
9mm buffer in 223 carbine?

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.
