Building out 2 AR's need some Oh-Pin-Yuns.

Recommended Posts

I have 2 spikes lowers sitting around and decided to build two identical his/hers rifles...

 

Purpose: SHTF durability.

 

I have most of the odds and ends figured out but 3 components im struggling with...

 

The FCG, LPK and BCG

 

I have an RRA 2-stage and a SSA-E installed in two AR's right now. I enjoy them both but lets be serious here, accuracy bench shooting is not the build purpose.

 

The ALG ACT trigger seems like a good option, Milspec+ and single stage = bullet proof.

 

any other good options?

 

 

LPK.. wtf man everyone makes one and then some... Both LPK's from my last build were RRA and were great, anything out there special durability wise?

 

BCG, nothing fancy, but again looking for solid durability/longevity.

 

I appreciate the input... The rifles are intended to be 14.5" + comp light weight rifles that can take a beating and still run.

I say go with the ALG ACT. If you want to lighten up the trigger pull further, add in JP Springs...

Seemed like the better option of what I found. Standard design but better materials. It's kinda what got me on a search for equivilant parts that are beyond milspec.

Although the RRA NM trigger is only $30 more than the ALG and it takes a lot of rounds before it starts wearing out. But I understand what you're saying about dependability.

As far as I know there is no reason not to go with the PSA premium full auto BCG on sale now for $89

Is it the same metallurgical composition though? I've used psa parts in builds and have had no issues but I feel there is a certain standard bcm is held up to.

Product descriptions are identical, literally.

 

BCM's price drops dramatically when u buy an upper with BCG add'on. I think i may go for their 14.5" mid stripped upper. Its a pretty good deal all said and done and im going to keep the FSB. They ran some good deals with a free BCG maybe they will do it again.

ALG ACT is an awesome value. Buy with confidence. I have then in both of my SHTF guns and my .40 AR.

 

The BCM trigger is fairly new. I don't think it has even hit the site for the initial sale yet. Not 100% on that though.

 

Guys that have had them for a while in a T&E run say they are good to go. I have not seen one in real life.

 

BCM is good to go for everything else - Uppers, BCG, etc... So I can't imagine the trigger isn't as well.

Don't skimp on the barrel, get the best one you can afford that is suited for your rifles purpose in life. It is the foundation of your build.  $300 trigger $150 Upper receiver, $250 free float handguard,  $200 BCG and a $85 crap barrel = crap rifle. 

 

Get the right twist rate for the ammo you will shoot the most.  If you are going to shoot cheap 55gr M193 and/or 62gr M855 then get a 1:9.

PSA bolt looks identical to BCM at half the cost..

from my PSA experience with lower parts kits, I'd go with BcM in a heartbeat. But I prefer the colt lower parts kit from g&r tactical for $60.

 

If you are looking for SHTF reliability why go with the cheapest BCG. that's probably the last place I'd skimp on.

I'd take a look at aimsurplus's NiB BCG's. I have one of their versions and it runs great. I'm sold on the nickel boron coating for its innate lubricity and ease of cleaning.

I actually would like to find 1:8 or 1:9 twist 14.5" barrel, but i haven't found much.

 

My DMR is 18" with a 1:7 rate, but it uses 69gr+

 

My "fun" AR has a 14.5" BCM 1:7, i cant find light weight 14.5" in 1:9. RRA makes a regular 14.5" but their barrels are on the heavy side.

 

Everyone uses 1:7 for some reason.

When i got my chromed BCG years ago, it seemed like great idea. Now i'm reading NiB is slightly more effective, i like the idea of a functioning rifle with little to no lube.

    • As I mentioned in another thread, we bought a condo in Florida a couple of years ago, and have started spending some time down here.  We have not become residents yet, but still are able to enjoy a taste of life in a free state with Covid sanity and everyday concealed carry. Yesterday I purchased the Zastava Arms ZPAP M70 for which I have been lusting.  Bought it online from Atlantic Firearms and had it shipped to a local dealer.  When I went over to pick it up, he asked me for my DL and Florida CCW permit (if I had one).  I filled out a 4473 and a few minutes later, he said, "You're all set."  Holy crap!  No waiting days for an "instant" background check requiring a return trip to the dealer.  In just minutes I was able to walk out with my new beauty.  While I was there, a fellow walked in and asked to look at a handgun.  He checked it out for a few minutes, then said, "OK, I'll take it."  Same deal for him:  DL, Florida CCW, 4473, and out the door in a few minutes with the gun.  I should note that with the ready availability of guns in Florida, contrary to the hysterical fears of legislators in states like New Jersey, not only do legal gun owners not run around shooting each other, one rarely (like, never) even sees a gun. All that aside, the weather here has been great, the people warm and welcoming.  On days when it's a little cooler, with temperatures in the mid-60's, when we can't sit by the pool or go to the beach, the weather is perfect for golf, pickle ball, running and working out, or just hanging out.  Unfortunately, we have to leave "The Matrix" next week to return to Jersey for six weeks in the middle of winter, for some weddings and other family events.  But we get to look forward to returning in mid-March for another 6-8 weeks.  If any of you are down this way, be sure to say hi!
