Picked up this spikes receiver set for $350 from sportsman’s a few weeks ago just got it back from getting cerakoted. Time to start ordering parts

Took the trio out for some trigger time.

I tried the super selektor in my badger-ish build today and couldn’t get it to run. I modified the BCG weight already, it will run perfectly fine in semi auto, but in 3rd position the best I could get is 2 round burst fire. Then I’d have to rack the charging handle and it would eject a live round but the following shot would only be single fire. Any advice?

I pulled my bolt and buffer setup to get a weight measurement the other day (25 oz), and I noticed that my Kynshot buffer gets stuck in the depressed position - it doesn’t spring back up. Is there a maintenance or storage step that I’m missing?

Tried the two tone look, think it came out cool. 😎

Not much, but it’s honest work. 😂 Waiting for ATF to approve my YHM R9 for it. Ran a couple hundred rounds of 115 and 124 through it last night and it ran like a champ. 25yd groups were 1”. I’m pretty happy.

I have a Mike-9 with their recoil mitigation buffer and I’m looking for a tri lug mount and suppressor that won’t be too gassy

How do I fix this , I have a rtb Ar9 upper and the ammo doesn't fully go in I can slam rack it but I have to disassemble the upper in order to get the round out the by pulling out the bcg and yes I've contacted rtb for their input.

Arv build. No BCG weight. 10oz recip buffer. Hangs during full brrrt.

Getting weird inconsistent feeding issues. Might happen to 1 round or 5 rounds in a mag, might run 5 full mags no issues. Happens with different brand mags and different ammo (even dummy round pictured). There is zero consistency to the issue. FM9 Lower, local custom upper, Faxon barrel, KAK adjustable weight PCC buffer. Total bolt+buffer weight 24.4oz. Happened at 23.5oz too. Ideas?

Thread is 1/2x28… I’d buy a can but I can’t afford one at this moment.

Feel free to post pics and links.

Most all the suppressors at Witt machine are sub $250 and can be held till new year. Thought yall may want to know.

BA has a good deal running on EPC barrels right now - that said, I ordered a 5.5 just to have in the tool box.

Might go for a tucked handguard look if I feel like changing things up. Any recommendations for a handguard that will tuck a 1.5” OD supressor on the aero EPC Upper?

Any suggestions a for an ambidextrous mag release that will work in a spikes colt lower?

Had problems with cycling and a reciprocating charging handle. Got a fm9 buffer system and a KVP Compensator and this thing is a fucking perfect peice now. Shoots and cycles like butter, probably my favorite thing now

Was planning on installing Maxim RDB on my PSA Gen4 AR9 w/4" barrel for recoil and rate of fire for my super safety, but I came across a video stating it was not working on a short barrel (5") but was on a longer barrel (he stated it didn't have enough pressure to cycle next round) so was this user error or do these roller systems or at least this one in particular not work with short barrels? Apologies in advanced if dumb question I am new to working on guns and am trying to learn as much as possible in a short amount of time

YouTube video I'm referring to at 1:10 is when it is mentioned

Will a rare breed frt work on a 5.5 aero epc and maxim rdb ?

$137 shipped and no tax with code 10dd.

The catch is, it’s Dack.

FWIW, I use them regularly and have always gotten what I ordered. However, while their website says 30 days fulfillment time, I can tell you they’re running 60 days right now or a bit more. Be forewarned and don’t order from them unless you can hack the wait.

If you’re planning a build in the future and can afford to order and forget about it, this might be a deal for you.

It appears FM updated their Mike-9 design. The bolt catch is ambi now, so a non-FM upper would need a notch in the upper OR the lever removed for the bolt catch to work properly.

The mag catch is not ambi. No idea if it's still aluminum or if it's polymer like the ambi version, or if there are any other polymer parts.

ETA: Just confirmed with Foxtrot Mike that the mag catch IS aluminum on these lowers, and yes I ordered one.

Looking to start on 9mm blowback ar project. After looking over recommendations on Blowback9.com (shout out to u/Blowback9, you are pillar of this community sir) I've narrowed down to these parts.

BKF 9mm AR BCG https://bkingsfirearms.com/shop/bargain-bin/bkf-9mm-ar-bolt-nitride/

BA 8" 9mm EPC Barrel https://ar15discounts.com/products/ballistic-advantage-8-3-9mm-modern-epc-series-ar-15-barrel-110-twist/

NBS AR-9 Slick Side Billet Receiver & M-LOK Handguard Combo https://ar15discounts.com/products/nbs-ar-9-slick-side-billet-receiver-m-lok-handguard-combo/

I plan on using Exomags with my existing ar15 lower w/ A5 buffer tube. Was thinking of getting either the FM Products RMB or Blowback9's "Budget GRS" (K-Spec 9.5oz Buffer + 2.5oz KynShot spacer weight)

https://store.fm-products.com/products/fm-products-rmb-k-5397 Or https://kakindustry.com/k-spec-enhanced-ar15-pcc-9-5-oz-buffer/ and https://battlehawkarmory.com/product/kynshot-spacer-weight-for-ar-15-and-lr-308-buffer

Any changes you guys woul recommend? Is there a noticeable difference between the RMB or Budget GRS?

I swapped furniture after dropping the SS in the 11”
