  1. About 5 years ago, I got rid of my PS90 (5.7×28) because of the expense and rarity of the ammo. Now that there are a few more firearms out there beyond FN products that use this round, is the price/availability getting any better?

  2. I just bought mine today, however the bullets I would have to buy from online b/c its rare here in Ohio. I am excited to shoot this bad boy when I get my bullets!

  3. Cmmg is that a new gun it's pretty cool looking the Banshee actually the Banshee have you heard of the scary stories about the Banshee it's a story she's always hiding in the Wilderness she's a story it means is not really real I don't know people say they believe it. But me I'm just don't believe ghost and spirit I believe god Spirit will be my right arm

  4. Quick question about this banshee. I'm in the process of trying to build one of these things. Other than using my AR-15 Lower. Will my AR-9 dedicated Glock lower fit the FN mags for the 5.7x28m? My intentions when I got the Glock lower ways to build a 5.7 x28 but if I can't use this I'll have to figure out what to do with it, I wanted a 5.7×28 and a 45 version. But I think the Glock lower I have will only fit 9 and 40s

  5. Currently looking to get the 8 inch upper for my ar pistol lower. Mine is midnight bronze and they happen to sell them in midnight bronze. I just gotta get my dealer to get me mags since I live in Colorado.

  6. Kinda new to the gun world for forgive my ignorance, I’m looking for an AR and the few I have in mind are, Cmmg 300 series, the PSA, gen 4, & brigade. The only reason why the CMMG is my top pick is (silly reason i know lol) the Mag, i do not like how the others look with the Glock style Mag, but I’ve notice that not all CMMG 300 Series has the style of Mag that you have in this Vid. Do they all take that Style of Mag or just the one you have? Thanks

  7. Cool gun! Enjoyed the review. A nice adjunct to a 5.56mm AR for small game hunting, which is a big step up from the .22 LR round. Needs a longer barrel though as 5" is way too short for this round in a carbine as it gives no better ballistics than the FN and Ruger pistols. Needs at least 8" IMO, but would prefer 10" as on the XM177E1 which is still a very compact AR. The 5.56mm round really needs 20" IMO. I would also prefer it without a forward assist (if only as an option) as I don't like them.
