What specific issues, good or bad, are there in an AR pistol build.
I really haven't thought much about them and so don't know much either,
Looks like it could be a good truck gun.
1. what about gas length/ performance, it's a shorter length than even carbine, right?
2. Are some bullet weights better than others.
3. effective range? Probably a smaller, shorter scope, or?
4. what special issues are there in ability to aim/ get on target accurately.
5. What braces, or not-a-buttstock-but helps stabilize it thingies, work well?
If I get into one of these, I would think it should be a 223 or 6.5 Grr.
Anyway, thoughts and experiences welcome!
1. The group buy barrels are carbine length. With his experience I would think BFT has got this nailed for a short Grendel. If you were talking about a 300 BLK, pistol gas would be the way to go for a shorty.
2. As far as bullet weight goes...just like any other rifle, shoot it and find out what it likes. Just because its short doesn't mean it will not like anything you don't already have.
3. A short Grendel has the most energy at downrange distances when compared to .223 and 300BLK. At short range (50-100 yards) they may be close but once you get out there the Grendel shines. There are threads here showing comparisons.
4. None that I have found. Raising a rifle/pistol and looking through a scope is the same motion whether its long or short. Short usually means lighter and therefore faster if need be. A short barrel with a suppressor mounted will end up at a carbine overall length.
5. A brace comes down to what you want it to do and how much you can afford. Since the ATF loosened their interpretation on them the options in the market have exploded. I have an original Sig brace and shouldering it (when it was and now again that it is legal) is no problem. It is not a stock but it comes close.
