Retay USA RA15-22 .22 LR 8" Barrel 25-Rds Tactical Pistol w/ Folding Brace, Black - $309.99

6/15/2026 - FWIW, KYGUNCO uploaded a short video of this firearm 6 days ago. At this time the vid has drawn only 15 comments.
These two snips from two of the comments might interest some of yall:
-- @edgardomeza2372 5 days ago - "...3 out of 10 mags ran had a few 3 rds bursts ..."
-- @jeremybrown_sc12v 2 days ago (edited) - "Had the gun for 2 weeks. It started running full auto."

Dirty Bird AR-15 SMRS Handguard – Slim M-LOK Rail System Gen 3 - from $59.95

That's because it is a "Sale!" item which is "Excluded from additional discounts". That wording is on the product page. Coupon codes can't be applied toward the purchase.

Smith & Wesson M&P Shield Plus 3.1" 9mm (1)15rd, (1) 13rd, (1) 10rd Optics Ready Pistol - $369.99

Was leaning toward a Micro Dagger, but at this price the Shield Plus is an easy winner. In day-to-day carry, the spec diffs will not be noticed. Smith &Wesson wins (again).

Alpha Foxtrot AF1911 70 Series 9MM 10RD 4.25″ Threaded Barrel Black DLC Polished - $489.99

Too bad it's only a 10 round pistol...and I can't tell but doesn't look like it's optic ready either. Even just with that, this is a great deal. Less than half of other dealers

Retay USA RA15-22 .22 LR 8" Barrel 25-Rds Tactical Pistol w/ Folding Brace, Black - $309.99

I have it in hand but haven't shot it yet. It's definitely AR-style and not a .22 conversion of a milspec AR. It's light, but it feels solid. All polymer except the barrel/BCG/spring/handguard. The barrel is threaded (which isn't mentioned in any of the marketing/spec) with a short slide-over thread protector that gives it the tucked look, but also makes it look a bit goofy with an actual suppressor mounted. The charging handle is polymer but feels up to the task... it also has a comically short pull-to-charge, which makes sense but isn't what you're expecting the first time given the AR ergonomics.

The folding "brace" is also made of polymer but feels relatively sturdy. I put "brace" in quotations because I'm really not sure how it passed ATF muster; it looks and feels like a minimalist stock with "Not a Brace" molded into the butt. I'm moving it over to my 3D-printed dagger chassis and putting an airsoft folding tube and SBA3 on this (repurposing the "brace" was half the reason I bought this).

I've had good luck with the RXP22 from Retay, so I'm hopeful for this one but, unfortunately, don't have any shooting experience to share just yet.

Mossberg MVP Precision 7.62 NATO (308 Win) Bolt-Action Rifle with 20 Inch Threaded Barrel - $799.99

Yeah, these were on close-out about 1 month ago for 500$. I had seriously considered one, but apparently accuracy was a real 50/50 toss-up, either you got a great one, or worse than 3 MOA, and nothing you could do to improve it, so I skipped.
