I recently purchased a Kel-Tec Sub 2000 Gen 2 that accepts Glock Magazines. ($429.00) The Gen 2 has several improvements over the Gen 1. The polymer encasement has been overhauled, trimmed, and textured. Railed surfaces have been added on the top and bottom of the handguard as well as M-lock slots on the sides. The front sight is metal (previously plastic) and adjustable as well as easily removable. The stock has 3 length adjustments.The rifle unmodified weighs 4.25 lbs.
I made several modifications:
1) Tacticool Buffer Cylinder-Reduce felt recoil up to 30% $9.50
2) Tacticool Bolt Tube Cover- Allows for wider and softer mount against chin. $14.25
3) Red Lion Precision Forend- This is machined forend that indexes so that you can mount scopes and grips and still fold the rifle. $149.00
4) Two full length picatinny rails. $62.00
4) Magpul forgrip. $30.00
The modifications make this gun feel much more solid than stock.
The rifle length is 28 inches open and 15 inches folded. With modifications it weighs just under 6 lbs.
I have experienced no issues shooting 100 rounds of various 9mm ammo. Open sight accuracy is good. I can hit 6 inch steel targets at 75 yards easily. I have yet to install an optic. The rifle disassembles easily for cleaning and lubing. This rifle is very fun to shoot!
