C&G Holsters Covert Mod1 IWB With Mag Holster RH Glock G43/G43X MOS - $84.99

Gunngle?? To OP: have either of you successfully purchased from "Gunngle.com?" I've never heard of it, and it's ringing scam bells. BBB doesn't recognize it. It doesn't use HTTPS or have a SSL certificate for purchase. Google maps doesn't show a store front. This is a good price on this holster package, but considering Gunngle's rather nasty return policy, poor credit card security and lack of history I would be inclined to pay 130 at C&G. I'm willing to here differently.......

One (1) Police Trade Bushmaster XM15-E2S 556 Nato 30-rds Hand Select Available 16" HBAR Barrel 1:9 Carry Handle Adjustable Stock - $569

Sadly, the Bushy XM15 is on the PRK's list of "by name" bannees, so even if you made it "featureless," it's still illegal behind the Granola Curtain. When is the SCOTUS going to get off their fat backsides and SUPPORT and DEFEND the 2A?

Also, this price is about 2/3rds what one co$t brand new prior to the '94 AW ban, and that was in '90s FRN$, which back then were worth about 2.5x what they are today...

Dark Mountain STOWAWAY 9mm 5" Barrel Single Shot Pistol w/ Brace Adapter - $388

I bought one for S's and Giggles, it was sitting on the counter with a folding SBA3 brace I said yea why not, I put a Primary arms slx3 on it. It's fairly accurate (1" @ 50yds), It has made a good impromptu Varmint/small game rifle and it allows me to reload 5.7x28 subsonic with heavy for caliber projectiles previously unheard of with the caliber.

ATI GSG-16 16.25" .22 LR 22-Rd Carbine Rifle, Black w/ DUO Red / Green Sight - $349.99

This is a fun plinker, but needs HV ammo (1280 fps works great for me) to cycle right. Warning, it's an absolute nightmare to clean without totally breaking it down and that in and of itself is a royal PITA.

Otter Creek Polonium 30 - $439.99 (Add to Cart for Best Price)

$439 is a great price. Of the poloniums the 30 is the least gassy on a 15. Still pretty gassy. I own all variants of the poloniums. They are very tough cans. Mostly they get used on bolt actions now. Baffle cans are bolt cans. I actually am the exact opposite of most. I like titanium on semi autos and steel on bolt guns. Sure titanium only can take 60 shots before cool. I let my barrels cool after 15. I like the light weight on a 15. On bolts I like steel doesn't get hot as fast. Less mirage.
If you want a can for a 15 do yourself a favor and pony up for a CAT or a,vent or a tisha. Low back pressure printed cans. Printed vs baffle.Your eyes and lungs will thank you. Baffle cans are bolt cans.. Printed are 15 cans. Sure you can screw that baffle can on your 15. Play with gas and buffers so it works. Your eyes and lungs will let you know after a while they are not happy. The polo and the enticer are awesome budget baffle cans. The titanium enticer or wolf hunter is a great do all can. Light enough for hunting. Not 15 cans.
The polo cans were a legacy. Great company. We have come a long way baby.

Ballistic Advantage 5.5" 9mm Barrel, Modern Series - $26.25 + FREE Shipping

Decent feed cone profile but not the new one. That's why. Ba is gone along with Aero. Maybe less barrels around.
