350 legend AR

[Ringbill27]

Anyone in here hunt will a AR?

I built one in 350Legend a few year back and had a bunch of issues with feeding. But I got that figured out for the most part.

Now the real question.
What trigger are you running for hunting? One or two stage?

Currently have a cheap mil spec that I actually shoot pretty accurately but it’s a long pull and feels like I’m pulling it down a gravel road.

Looking to upgrade to a cost effective drop in.

I run a two stage RRA Varmint trigger. Like it a lot and not that expensive. Under $100.

Are you still having feed issues? I had the same thing, ended up having to use 5.3 oz buffer weight and 170’s. I think the bcg was cycling so fast it didn’t strip off my next round.

Once in an awhile it will jam. I’m using a H2 buffer because it definitely was running too fast. I should order an adjustable gas block. But a majority of the issues were from the mag. It seemed that there was way too much tension on the round and the BCG was struggling to strip the round out. I removed a lot of the unused coils in the spring. Also noticed the case lips were catching the front of the mag when being stripped. So ground the mag lips so the round couldnt make contact.

I sighted in the other day and had a few jams so I got more aggressive with the grinding and the spring clipping.

I think after deer season along with a new trigger I’m switching to an adjustable gas block.

Sounds a lot like mine. I got the adjustable buffer from oden and a couple different weight projectiles. I think the standard weights are setup for 556 and the other calibers take a little playing around to get them dialed

I' ve hunted with an ar15 in 450 bushmaster the last several season's in Ohio . Currently I'm building a 350 legend upper that will hopefully be ready for this year. As far as triggers the geissele ssa-e is the best I've used but the rock river varmint and the Schmitt nickel boron two stage are both decent budget triggers

What fixed my 350 legend upper was simple and free. Grind the magazine feed lips back to the middle of the first groove on the side of the mag. This allows the round to have a slightly nose up attitude. Worked wonders. The full diameter on the Legend is much further forward than the shoulder of a 223 round.

I mostly run two stage triggers in my ARs but have some single stage as well. To me, it depends on what I primarily built that particular AR for to which trigger I put in it. That said, my dedicated hunting ARs tend to have single stage triggers in them.

 

[VuduDoc]

Careful with a cassette-style drop-in if you’re planning on hunting in really cold weather. I’ve had poor luck with multiple brands having light strikes in below freezing temps. The one I had no problems with was a CMC 3.5lb single stage flat bow. The Timney Impact was bad. I switched back to milspec or improved milspec like ALG ACT. Wanting to try a LaRue MBT-2S and Geissele SSA-E.

I have a Rise Armament single stage that I really like that is on the cheaper end of the budget. Got a buddy that prefers two stage and he keeps ordering the RRA triggers for me to install for him.

The 350 Legend is tough on feeding ramps. I’ll carry my AR in 300blk with 110 gn Barnes. Performs super well out to 200. Second on the RRA trigger for cost effectiveness. Anything more and the trigger will out perform what the 350 Legend round is capable of

More or less looking to take the gravel road out of the trigger.

I’m using a larue mbt-2s on mine.

Do yall without feeding issues have m4 feed ramps? The feeding on mine sucks and I’ve tried a few things, I’m about to give up.

Have you tried grinding the magazine feed lips back to the middle of the first groove you come to?

 

[bigbuckdj]

First groove being where that notch is? 1/4” or so? I’m gonna mow down the front a touch as well. Definitely need a nose up attitude, it’s just slamming so flat into the feed ramp.

Grind that lip down the case lip is catching it.

How do you like that ammo? Bear creek?

Yeah, it’s the 140 grain. I haven’t shot anything with it but it shoots as well as anything I have. Hopefully my feeding issues are resolved soon and I’ll take it hunting.

Yep right to the center of the notch. I have ground a bit of a ushape from the front wall of the magazine also. Part of the magazine issue is the cartridge needs to pop out of the feed lips sooner.

Cool, I got a dremel and a bad attitude. Ill report back
