Looks good. Man, that's alot of $$ invested in a .22.
Not really. All the parts that's been added to that 15-22 are standard AR parts. So if he likes, he can use them on any other AR that he has. And when you are talking about the AR platform in general, he's only scratched the surface of spending money on upgrades. The last AR I built from the ground up came out to about $2500 without optics.
In case anyone was wondering how much it probably cost him to build it up this way.
M&P15-22 rifle - $500 (probably less)
Magpul CTR - $115 (or less)
LaRue Indes Clips $20
Hogue Grip - $18
Larue Offset Mount - $89
Tango Down VFG ~ $85
Magpul MBUS front and rear $100
Eotech 511 - $350
Blue Force Vickers Sling $59
GG&G sling thing mount $35
4 extra 15-22 mags $80
Grand total $1451 (not including shipping costs). But My numbers are probably a little high. The only accessory on that list that cannot be used on any other AR, or just about any modern battle rifle, is the 4 extra magazines. So I'd say it's more of an investment in a system than it is on a specific rifle.
I know people who have over $1200 invested in a 10/22 not counting optics. And none of that is reusable in any other firearm.
I'll be working on building mine up to match my regular AR over the next few months (after Christmas). My list of parts is very close to maxicoopers list.
Modified safety selector (ambi safety)
Norgon ambi-catch (already installed)
Magpul CTR
Magpul MIAD grip
Magpul MBUS front and rear
Larue FUG
Larue Index Clips
MS2 Sling
slings mounts (haven't decided which ones yet)
Eotech XPS2
I'm also going to get the BBL threaded for FH/Supressor and then a Gem-tech outback II will be the final item. But these item's are the last on the priority list right now.
Great job on the M&P15-22 maxicooper. Enjoy.
